2.5 Main circuit terminals (G type)
PE Earth terminal
The main circuit terminals are located on the front and bottom of the inverter. The small-capacity model
is placed directly on the main circuit printed circuit board, and the medium and large-capacity models
are fixed on the chassis. The number of terminals and their arrangement positions vary depending on
function and capacity. See below for details:

2.5.3 Main Circuit Wiring Precautions
1)Input power R, S, T:
Note that after the power failure, the DC bus (P+) and (P-) terminals have residual
voltage. After the panel is not displayed, confirm the power failure for 10 minutes
before wiring operation, otherwise there is danger of electric shock.
When using an external brake assembly of 45kW or more, be careful that the (P+) and
(P-) polarities cannot be reversed, otherwise the inverter may be damaged or even fire.
The wiring length of the brake unit should not exceed 10m. Twisted pair or tight two-
wire parallel wiring should be used. Do not connect the braking resistor directly to the
DC bus, which may cause damage to the inverter or even fire.
Refer to the recommended values for braking resistor selection and the wiring
distance should be less than 5m. Failure to do so may result in damage to the
inverter.
4)Output power U, V, W:
The specifications and installation methods of the external power wiring must
comply with local regulations and relevant IEC standards.
Refer to the wiring shown in Table 3.2.2 for power cable wiring.
The capacitor side or the surge absorber cannot be connected to the output side of
the inverter, otherwise the inverter will be often protected or damaged.
When the motor cable is too long, due to the influence of distributed capacitance, it is
easy to generate electrical resonance, which may cause motor insulation damage or
generate large leakage current to protect the inverter from overcurrent.
32
When the motor cable length is greater than 100m, an AC output reactor must be
installed near the inverter.
5) Ground terminal PE
The terminals must be reliably grounded and the ground wire resistance must be
less than 10Ω. Failure to do so may result in abnormal or even damage to the
equipment.
Do not share the ground terminal with the power supply neutral N terminal.

AI1,AI2 can be chosen as 0V~10V voltage input as well as 0mA~20mA current input by the jumper
J3,J4 on control board.
AI1、AI2 input voltage value has a corresponding relationship with target frequency, users can choose
them at will. MR590AL offers 5 groups of corresponding relation curve, which 3 of them are linear
relationship(2-point correspondence), 2 of them are 4-point correspondence(any curve among them). User
can set through P4 group or A6 function code.
Function code P4.33 is used to set AI1~AI22-channel analog input. Choose 1 curve among the 5

5:Pulse setup(DI5)
Pulse setup is set through terminal pulse. Signal standard:voltage range 9V~30V, frequency range
0kHz~100kHz. Set pulse can be only input through multi-function input terminal DI5.
Relationship between DI5 input pulse frequency and corresponding settings is set through P4.28~P4.31.
It is linear relationship(2-point correspondence). Pulse input 100.0% refers to the percentage of P0.10 .

When the auxiliary frequency source is used as independent frequency reference channel (i.e.
frequency source switching from X to Y), it is used in the same way as the relative specifications of P0.03.
When the auxiliary frequency source is used as overlap reference (i.e. frequency source selection
switching from X plus Y or X to X plus Y), it has special points as follows:
1. When the auxiliary frequency source is digital reference, the preset frequency (P0.08) is
nonsensical, and it needs to adjust the main reference frequency through the keys “∧ ”and “∨ ” of the
keyboard (or UP and DOWN of multifunctional input terminals).
2. When the auxiliary frequency source is analog input reference ( AI1、AI2、AI3) or pulse input
reference, 100% of input setup is relative to the auxiliary frequency source range,and can be set through
P0.05 and P0.06.
3. When the frequency source is pulse input reference, it is similar to the analog value.
Prompt: There is difference between the auxiliary frequency source Y selection and the main
frequency source X setup value. That is to say, P0.03 and P0.04 cannot use the same frequency reference

2:Switching between main frequency source X and auxiliary frequency source Y
When terminal 18 (frequency switching) is invalid, main frequency X is target frequency. On the
contrary, auxiliary frequency Y is the target frequency.
When terminal 18 (frequency switching) is invalid, main frequency X is target frequency. On the
contrary, auxiliary frequency Y is the target frequency.
When terminal 18 (frequency switching) is invalid, auxiliary frequency Y is the target frequency. On the

Operation result of main + auxiliary is target frequency. It realizes frequency stacking set function.
Besides, when frequency source is main& auxiliary operation,users can set offset frequency through
P0.21.By stacking offset frequency on main& auxiliary operation result,it could flexible cope with all
kinds of needs.
When set the frequency source to “digital setting” or “terminal UP/DOWN”, the parameter value is the
initial value of the inverter frequency digital setting.

When needing to change the rotary direction of the motor, users can modify this parameter rather than
adjust the wiring of the motor.
Caution: When the function code is restored to the factory default value, this parameter value is
restored to 0, which should be used prudently in the applications where the motor rotary direction is not
allowed to change.

It defines the source of frequency upper limit. Frequency upper limit comes from digital setup (P0.12)
or analog input channel. When upper limit is set through analog input, 100% of analog input corresponds to
P0.12.
E.g : When winding control field is in the torque control mode, to avoid material break
phenomenon,users can set upper limit frequency through analog value. When running frequency reaches
value of upper limit , inverter maintains operation at the upper limit frequency.
When upper limit is set through analog value or PULSE setup, P0.13 will be used as analog
valueoffset. The addition of offset frequency and analog setup value of frequency upper limit is used as
the final setup value of frequency upper limit.

P0.15 Carrier frequency 0.8kHz~8.0kHz - ☆
This function is used to adjust the carrier frequency of the inverter. By adjusting the carrier
frequency, the motor noise can be reduced, the resonance of the mechanical system can be avoided, so
that the leakage current to the ground and the interference of the inverter can be reduced.
When the carrier wave frequency is low, the output current higher harmonic component will be
increased, the motor loss will be increased, and the motor temperature rise will also be increased.
When the carrier wave frequency is high, the motor loss is reduced, and the motor temperature
rise is reduced, but the inverter loss and inverter temperature rise will be increased, and thus the
interference will be increased.
The adjustment of carrier frequency will influence the following items on the performance:
Different power of inverter is set with different carrier frequency by the factory. Though user could
modify it , attention should be paid:if carrier frequency is set higher than the factory set valule, it will
lead to inverter radiator temperature rise increasing. User should take inverter derating use, or there
will be danger of overheating alarm.

For better VF or vector control performance, users should tune the motor parameter. The accuracy of
the regulation results has intimate relationship with the accuracy of set motor nameplate parameters.
P1.06~P1.10 are parameters for asynchronous motor.Generally, motor nameplate dosen’t contain
such parameters, users can get them throng inverter auto tuning. Among them, 3 parameters
(P1.06~P1.08) can be get through “ asynchronous motor static tuning”, while all the 5 parameters as well
as encoder phase ,current loop PI etc can be get through“asynchronous motor complete tuning”. When
change the motor rated power (P1.01) or motor rated voltage (P1.02), inverter would automatically
modify the P1.06~P1.10 parameter value and restore them to common standard of Y series motor

phase sequence through asynchronous motor complete tuning or synchronous motor no-load tuning.
Rotary transformer is equipped with pole pairs.When using the encoder, correct parameters must be
set to it.
It is used to set inspection time of encoder disconnection fault.When feedback signal is 0.0s,
encoder disconnection fault will not be inspected.

Asynchronous complete tuning can guarantee inverter dynamic control performance. Motor and the
load should be disconnected to keep motor complete status.
In the process of asynchronous complete tuning , asynchronous complete tuning is taken first, and
then accelerate to 80% of motor rated frequency according to PL.12. After keeping the state for a period
of time, then decelerate to stop according to PL.13 and stop tuning.
Before asynchronous complete tuning , users should set motor type and motor nameplate

Users could choose different speed loop PI parameters under different running frequency. When
running frequency is less than the switching frequency(P2.02), adjusting parameters for speed loop PI are
P2.00 and P2.01. When running frequency is greater than the switching frequency (P2.02), adjusting
parameters for speed loop PI are P2.03 and P2.04. Speed loop PI parameters between switching
frequency1 and switching frequency2 are two groups of linear switching. As shown in fig.5.2:

Users can adjust vector control speed dynamic response characteristics through setting proportional
coefficient and integration time of the speed regulator.
Both increasing proportional gain and reducing integration time can accelerate the speed loop
dynamic response.But excessive proportional gain or insufficient integration time may led to system
oscillation.
If the factory parameters can not meet the requirements, users can fine-tuning it on the basis of factory
value parameters. First increase the proportional gain to restrain system oscillation,then reduce integration
time so that system has fast response characteristic and smaller overshoot.
Notice:Improper PI parameter setting may lead to excessive speed overshoot , even voltage fault
during overshoot drop.
This parameter is used to adjust motor steady speed precision for zero-speed sensor vector control
mode. Please turn up the parameter value when with load motor running in low speed. On the contrary,
when the with load motor running in high speed, please turn down the parameter value.
This parameter is also used to adjust the output current value with the same load for speed sensor
vector control.
Generally speaking, the parameter needs not to be modified. Users could properly increase the
79
filtering time when speed fluctuation is relatively big, and decrease the value when motor oscillation occurs.
If filtering time is small, inverter output torque might fluctuate greatly, but response speed will be fast.

Inverter output frequency and output voltage are mutually independent. Output frequency is decided
by frequency source,while output voltage is decided by P3.13(VF separation voltage source).
VF complete separation mode is generally applied in induction heating, inverter power supply, torque
motor control fields etc.
In this case, V is proportional to F. Proportional relationship can be set by the voltage source
P3.13. The relationship between V&F is connected with P1 group(motor rated voltage and rated
82
frequency).
Suppose that voltage source input is X (X from 0~100%), the V,F relationship is:

To compensate the low frequency torque characteristics of V/F control, boost compensation should be
made to inverter low frequency output voltage.
Torque hoist: it will be set according to the percentage of input rated voltage to the inverter. Below
are explanations of setting torque increase:
1) When the torque hoist is set as 0.0%, the inverter will aYpt auto torque hoist.
2) This parameter can be properly hoisted for small motor, while for large motor; the parameter can be
properly decreased.
3) If the torque hoist is set to be too large, the motor may be overheated, and the inverter may be
over-current.
Torque hoist cut-off frequency: As shown in Fig. 5.3, the torque hoist is valid when the cutoff
frequency below this setting. Otherwise, the torque hoist will be invalid.

The setup value of multi-point V/F curve is generally set in accordance with the load characteristics of

Caution:
2) If the voltage is set too high at the time of low frequency, it may cause overheating and even

VF slip compensation can compensate asynchronous motor speed deviation ,in this way ,motor rotary
speed could be maintained in basically stable state during load change. In general, 100% corresponds to
the rated slip of the motor with rated load. For motor rated slip , it can be get through auto calculation of P1
motor rated frequency and rated revolving speed.
The slip compensation gain adjustment may be performed referring to the following principle: When
the load is rated load, and the slip compensation coefficient is set to 100%, the rotary speed of the motor is
84
close to the reference speed.
In the applications where over-voltage alarm easily occurs, it needs to improve the over-excitation
gain. Excessive over-excitation gain easily lead to increasing of output current .Users should keep the
balance during operation.
In the applications where the inertia is very low, the over excitation gain is set to 0, while in the
applications where there is brake resistor ,the over excitation gain is set to 0 as well.

When the motor has no oscillation, please select this gain to 0. Only when the motor has obvious

oscillation suppression result will be.
The gain shall be set as small as possible under the condition that the oscillation is suppressed
effectively so as to avoid high influences on the V/F operation.
Accurate motor rated current and no-load current parameters are required during using oscillation
suppression function, or VF oscillation suppression effect will not be excellent.

When the DC brake time is non-zero value, it can perform DC brake before start. It is suitable for the
applications where small inertia may cause Reserved rotation at the time of startup.
The inverter firstly judges the revolving speed and direction of the motor and then starts at the
frequency corresponding to the tracked rotation velocity of the motor, and performs smooth startup of the
motor in rotation without impact.It is suitable for the applications where large inertia is restarted due to
111
transient power shutdownIn order to ensure the performance of the rotation velocity tracking startup, motor
parameters (Group P1) should be set correctly.
It is only valid for asynchronous motor , and is used to establish magnetic field before motor operation.
For pre-excitation current, pre-excitation time please refer to function code P6.05 and P6.06.
If pre-excitation time is set to 0, the pre-excitation process will be canceled ,and start with start
frequency. If pre-excitation time is not set to 0, inverter first pre-excitation then starup. In this way, motor
dynamic response performance is promoted.
This mode only used in svc control of asynchronous motor. It can reduce the start time.
In order to complete the rotation speed tracking process in the shortest period, it can select the mode
of inverter tracking the rotation velocity of motor:
0: Track downward from the frequency at the time of stop, which is generally selected at first.
1: Track upward from zero frequency, which is used when the inverter is restarted upon long period of

2: Track downward from the maximum frequency, which is generally used for power generating load.

value is relative to the percentage of rated voltageof the motor.
Overvoltage stall gain: It adjusts the inverter’s capacity in suppressing the voltage stall. The bigger
the value is, the stronger the capacity is. For the load with small inertia, the value should be small.
Otherwise, the dynamic response of the system would be slow. For the load with large inertia, the value

To ensure the torque at the time of startup, proper startup frequency shall be set. In addition, in order
to set up magnetic flux when waiting for the startup of the motor, the startup frequency shall remain for a
certain period of time before accelerating to the setup frequency.
Start frequency PL.10 is not affected by the lower frequency limit.If the frequency reference value
(frequency source) is lower than the startup frequency, the inverter cannot start and will be in standby
status.
In positive&negative switching process, startup frequency retention time Yes not work.Startup
frequency retention time is not included in the acceleration time,but included in the simple PLC running
time.
Example 1:

Torque set is a relative value, which 100% corresponding to inverter rated torque. Set range:

When the torque is set by selection 1~7, 100% of communication ,analog input, pulse input
corresponding to A0.03.
A0.05, A0.06 are used to set forward or Reserved maximum running frequency in torque control mode.
In inverter toque control mode, if load torque is less than motor output toque, the motor revolving
speed would speed up. In case of galloping or other accidents of mechanical system , motor maximum
160
revolving speed must be limited.
In torque control mode , rate of speed change of motor and load is decided by the difference
between motor output toque and load torque. Therefore, motor speed may change fast, causing noise
or excessive mechanical stress problems. By setting the torque control acc./dec. time, can make the
motor speed changes smoothly.
A0.07 and A0.08 should be set to 0.00s in situations where torque rapid response is needed.
E.g:Two motors drive the same load, to make sure of load uniform distribution , one is set as host
inverter(speed control mode) and another is the slave one(torque control mode). Actual output torque of
the host inverter is the torque command of the slave, and slave torque is requir ed to quickly follow the
host torque, then torque control acc./dec. time is set to 0.00s for the slave inverter.

determine the continuous modulation mode. Wave value < A5.00 : 7-stage continuous modulation
mode. Wave value>A5.00:5-stage continuous modulation mode.
In 7-stage continuous modulation mode, inverter switch loss is relatively big, but current ripple is
small. In 5-stage continuous modulation mode, inverter switch loss is relatively small, but current ripple
is big. High frequency may lead to motor operation instability, generally there is no need of modification .

Synchronous modulation 1
This parameter is only valid for VF control mode. Asynchronous modulation refers to carrier
frequency that linear changes with output frequency, and ensure that the ratio of them (carrier ratio)
remains the same. Generally high output frequency is benefit for output voltage quality.
Generally, synchronous modulation is not needed at low frequencies ( below 100Hz), because the
ratio of carrier frequency and output frequency is relatively high,asynchronous modulation advantage is
more obvious.
When running frequency is greater than 85Hz, synchronous modulation is valid. And fixed as

Analog input AI1~AI3 of MR590AL are all provided with hopping function for set value.
Hopping frequency refers to fixing of analog corresponding setup to the value of hopping point
when analog corresponding setting varies within jump point upper/lower limit.
E.g:
Voltage of analog input AI1 is in 5.00V fluctuation, which range is 4.90V~5.10V. Minimum input
0.00V corresponding to 0.0%, while maximum input 10.00V corresponding to 100.%.The corresponding
setting of AI1 fluctuates between 49.0%~51.0%.
Set A5.16 to 50.0% and A5.17 to 1.0%, after hopping function processing, AI1 is fixed as 50.0%. In
this way, AI1 is converted into a stable input, and fluctuation is eliminated.

This group of function codes are used for calibration of analog input AI , which could eliminate AI
input bias and gain influence. Generally , there is no need of calibration in application, for it has been
calibrated in factory. When restoring the factory value, the parameter would be restored to the default
value of factory calibration.
Measured voltage refers to the actual voltage that has been measured through measuring
instrument such as multimeter. Display voltage refers to the display value that has been sampled by the
inverter. See U0 group (U0.21、U0.22、U0.23) display.
During calibration, put the multimeter measurement value and the U0 value respectively into the
function codes above, inverter would automatically calibrate the AI zero off and gain.

7-3 Storage
The following actions must be taken if the frequency converter is not put into use
immediately after delivery to the user and need to keep well for the time being or stored for
a long time:
※ Stored in a dry and adequately-ventilated place without dust and metal powder at the
temperature specified in the specifications.
※ If the frequency converter is not put into use after one year, a charge test should be
made, so as to resume the performance of the filtering capacitor of main circuit in it. For
charging, a voltage regulator should be used to slowly increase the input voltage of the
frequency converter until it reaches the rating, and the charge should last more than
1~2 hours. This test should be made at least once a year.
※ Don’t perform breakdown test at Random, for this test will cause shorter life of the
frequency converter. The insulation test must be performed after the insulation
resistance is measured with a 500-volt mega ohm and this value must not be less than
4MΩ.
196
※ If the three-phase output voltage is measured with a general multi-meter, the read data
is not accurate due to the interference of carrier frequency and only for reference.
※ Avoid metal parts leaving in the drive, or it may result in equipment damage.

Appendix I RS485Communication Protocol
The serial communication protocol defines the information content and format of
the use of the transmission in serial communication. Including: the host polling (or
broadcast) format 、 host encoding methods. Concent including: require action of the
function code, data transmission and error checking and so on. Slave machine's
response is the same structure, including: action confirmation, return data and error
checking. Slave error occurred when receiving information, or can not do what the host
request action, it will organize a fault messages the response back to the host computer.
Application mode:
The inverter accessing with “ single main multi-slave” PC/PLC control network
which equipped with RS485 bus.
Bus structure:
Asynchronous serial, half-duplex transmission. At the same time host and slave
computer can only permit one to send data while the other can only receive data. Data
in the process of serial asynchronous communication is in the message format and sent
198
one frame by one frame.
In single-master system, the setup range of slave address is 1 to 247. Zero refers
to broadcast communication address. The address of slave must is exclusive in the
network. That is one condition of one slave machine.
The entire message frame must be used as a continuous stream. If the pause time
frame prior to the completion of more than 1.5 byte times, the receiving device will
refresh the incomplete message and assumes that the next byte will be the address field
of a new message. Similarly, if a new message starts in less than 3.5 bytes times
following the previous message, the receiving device will consider it a continuation of the
previous message. This will set an error, as the value in the final CRC field will not be
valid for the combined messages.A typical message frame is shown below.

I-4 Cyclical Redundancy Check:
Cyclical Redundancy Check—CRC mode:CRC(Cyclical Redundancy Check) is in
RTU frame format, message contains an error-checking field that is based on a CRC
method. The CRC field checks the contents of the entire message. The CRC field is two
bytes, containing a 16-bit binary value. The CRC value is calculated by the transmitting
device, which appends the CRC to the message. The receiving device recalculates a CRC
during receipt of the message, and compares the calculated value to the actual value it
received in the CRC field. If the two values are not equal, an error results. The CRC is
started by 0xFFFF. Then a process begins of applying successive 8-bit bytes of the
message to the current contents of the register. Only the eight bits of data in each character
are used for generating the CRC. Start and stop bits, and the parity bit, DO not apply to the
CRC.
During generation of the CRC, each eight-bit character is exclusive XOR with the
register contents. Then the result is shifted in the direction of the least significant bit (LSB),
with a ZERO filled into the most significant bit (MSB) position. The LSB extracted and
examined. If the LSB was 1, the register then exclusive XOR with a preset, fixed value. If
the LSB was 0, no exclusive XOR takes place. This process is repeated until 8 shifts have
been performed. After the last (8) shift, the next eight-bit byte is exclusive XOR with the
register’s current value, and the process repeats for 8 more shifts as described above. The
final contents of the register, after all the bytes of the message have been applied, is the
CRC value.
When CRC appended to the message, the low byte is appended first, and then the
high byte.

I-5 Communication parameter address
The chapter is about communication contents, it’s used to control the inverter operation,
the status of the inverter and related parameter setup. Read and write function code
parameters (Some function codes are not able to be changed, only for the manufacturer
use.). The mark rules of function code parameters address:
The group number and mark of function codes are parameter address for indication
rules.
Some parameters can not be changed during operation, some parameters regardless
of the kind of state the inverter in, the parameters can not be changed. Change the function
code parameters, pay attention to the scope of the parameters, units, and relative
instructions.
Besides, if EEPROM is frequently stored, it will reduce the service life of EEPROM. In
some communication mode, function code needn’t to be stored as long as changing the
RAM value.
Group P: to achieve this function, change high order F of the function code address
into 0.
Group A: to achieve this function, change high order A of the function code address to
be 4.
Function code P3.12 can not be stored into EEPROM, address indicates to be
030C,function code A0-05 can not be stored in EEPROM, address indicates to be 4005;
This address can only act writing RAM, it can not act reading, when act reading, it is invalid

This parameter is used to set the data transfer rate between the host computer and
the inverter. Caution:The baud rate of the position machine and the inverter must be
consistent.
Or,communication is impossible.The higher the baud rate is,the faster the communication
is.
The data format of the position machine and the inverter setup must be consistent,
Otherwise communication is impossible.
When the local address is set to 0, that is the broadcast address, achieve position
machine’s broadcast function. The local address is unique (except for the broadcast
address), which is the basis for the position machine and the inverter point to point
communication.
Response delay: It refers to the interval time from the inverter finishes receiving data to
sending data to the position machine. If the response delay is less than the system
processing time, then the response based on the time delay of the system processing time.
If the response delay is more than the system processing time, after the system process
the data, it should be delayed to wait until the response delay time is up, then sending data
to host machine.
