Use three-phase cage reaction motor with capacity suitable for the inverter.
When one inverter is used to drive several motors, the total current of all motors running
simultaneouly must be less than the capacity of the inverter, and each motor has to be
equipped with a proper thermal relay.
Do not add capacitive component, such as a phase capacitor, LC, or RC, between the inverter
and the motor.
14
▓ Precautions for peripheral applications:
Power source:
Make sure the voltage applied is correct to avoid damaging
Power
the inverter.
A molded-case circuit breaker must be installed between
the AC source and the inverter.
Molded-case circuit breaker:
Molded-case
Use a molded-case circuit breaker that conforms to the
rated voltage and current of the inverter to control the
power ON/OFF and protect the inverter.
Do not use the inverter as the switch for run/stop switching.
Magnetic
Leakage breaker:
contactor Install a leakage breaker to prevent error operation caused
by electric leakage and to protect operators.
AC reactor Magnetic contactor:
for power Normal operations do not need a magnetic contactor. But a
contactor has to be installed when performing functions
such as external control and auto restart after power
failure, or when using brake controller.
Input noise Do not use the magnetic contactor as the run/stop switch
filter of the inverter.
N2 inverter
Reactor for power improvement:
When inverters below 200V/400V 15KW are supplied with
high capacity (above 600KVA) power source, a reactor
can be connected to improve the power performance.
15
Make external connections according to the following instruction. Check connections after
wiring to make sure all connections are correct. (Do not use the control circuit buzzer to
check connections)
(A) Main circuit’s wiring must separate from other high voltage or high current power line to
avoid noise interference. See figures below.
The inverter uses dedicated power line A general noise filter may not provide
rightful results

When the connection between the inverter and the motor is too long, consider the voltage drop of the
circuit. Phase-to-phase voltage drop (V) =
3 ×resistance of wire (Ω/km)×length of line (m)×current×10-3. And the number of carriers must be
adjusted based on the length of the line.
(B) The wiring of the control circuit must be separated and routed away from the main circuit control
line or other high voltage or current power lines to avoid noise interference.
To avoid error actions caused by noise interference, shield the control circuit wiring with a
twisted wire, and connect the sheilding wire to a ground terminal. See the figure below.
(C) Ground the ground terminal of the inverter properly. 200V class: Ground to 100Ω or less, 400V class:
Ground to 10Ω or less.
Ground wiring is based on the electrical equipment technical basis (AWG) and should be made
as short as possible.
Do not share the ground of the inverter to other high current loads (welding machine, high
power motor). Connect the terminal to its sole ground.
Do not make a loop when several inverters share a common ground point.

Fn_12: Stall Prevention
Note:
1. If the acceleration ramp time is set to fast for the size of the load, an over-current trip may
occur during the acceleration period. Setting the proper stall prevention during acceleration
can automatically extend the ramp time to prevent trip when acceleration time is too short.
2. If deceleration time is to short, an over-voltage may occur on DC BUS. Setting the proper stall
prevention during deceleration T-verter can prevent an “OV” trip when deceleration time is
too short.
3. In order to prevent abnormal overload trips during heavy running periods, the T-verter can
lower the output frequency in accordance with deceleration time set by (Fn_02) or (Fn_15)
when (Fn_12) is (1xxx) or when operational current is over the value set in (Fn_14) The
T-verter will return to its normal operating frequency automatically after the current is back to
normal conditions.
36
Fn_16: Direct Start / Scanning / Reset Options
Note:
1. When (Fn_16) is set at (xxx1) and the control mode is set for terminal 2 control (Fn_10), the
T-verter cannot start if the RUN switch is on when the power is engaged. The “STP1” LED
will flash. On the Keypad the RUN switch must be turned OFF and ON again, in order for the
T-verter to start.
2. Scanning the input signals at TM2 on terminals (3) (4) (5) (6) (7) (8) (9)
(FWD) (REV) (SP1) (SP2) (SP3) (RESET) are set at (Fn_16). If TM2 detects the same input
signals for the programmed number of times in a row, the T-verter will treat the signal as a
normal signal and execute it.
On the other hand, if TM2 detects the same input signals that are less than the number of times
programmed, TM2 will interpret the signal as noise. Remark: The scan time is 2 ms
37
Fn_24: Jog Speed Reference = 0 - 400 Hz
Note:
1. The T-verter will be operating under the Jog Speed function at (Fn_24) you can assign either
(Fn_56) (Fn_57) or (Fn_58) to handle the jog function.
2. The T-verter will operate under the Pre-set speed frequencies when (Fn_56) (Fn_57) or
(Fn_58) are assigned to this function.
3. If the process timer in (Fn_84) is turned on and (Fn_56) (Fn_57) or (Fn_58) have been
assigned for input functions, if a pulse signal or contact closure is received on the
multi-function input, the T-verter will run at the pre-set time based on the setting in (Fn_85)
(Fn_86) (Fn_87) (Fn_88) (Fn_89) (Fn_90) and (Fn_91), The sequence will continue until all
process timers are finished, the T-verter will then returns to the frequency set by keypad or
an external Speed Pot or jump back to 0 speed to receive the next sequence.

Fn_30: Input Voltage Selection
1. Inverter will stop when the voltage is lower than the low voltage protection level. The
Inverter can restart automatically by using the speed search function.
2. During a Momentary Power Loss, the response time may vary slightly between each model,
the response range will be restored accordingly from 0.7 sec to 2 sec.
3. When Fn_32=XXX0:
(1)Power up after momentary power loss, the inverter will not start. Even under Fn_35>0.
(2)If the momentary power loss is long, the inverter must be restart manually. The operation
of the inverter is based on the setup of Fn_10/16 and the condition of external switch.
4. When Fn_32=XXX1:
(1)If the momentary power loss is less than Fn_31, the inverter resumes operation
automatically via speed search at 0.5 seconds after power up. The number of
auto-restart times is not limited by Fn_34.
(2)If the momentary power loss is long, the operation of the inverter is based on the setup of
Fn_10/16 and the condition of external switch.
(3)If the time of momentary loss is between the above two, whether the inverter will
auto-restart depends on Fn_35:
1.Fn_35=0: auto-restart disabled.
2.Fn_35=1~10: auto-restart enabled 1~10 times.
5. When restart the inverter, the operation of the inverter is based on the setup of Fn_10/16
and the condition of external switches (FWD/REV button).
(1) When Fn_10=0, the inverter will not start after restart.
(2) When Fn_10=1 and the external switch (FWD/REV button) is OFF, the inverter will not
start after restart.
(3) When Fn_10=1 and the external switch (FWD/REV button) is ON, and Fn16=XXX0, the
inverter will start automatically after restart. Attention: Base on safety reason, please
turn off the external switch (FWD/REV button) after power loss to avoid possible damage
to the machine and the human body after sudden regeneration of power.

Fn_34: Auto Restart Interval: 0.1 ~ 800 sec
1. When Fn_35=0, the inverter will not auto-restart after a malfunction break away from
operation. (Except for momentary power loss, please refer to Fn_31/32 for details)
2. When Fn_35>0, Fn34=0: The inverter will use speed search to pull the frequency back to the
frequency before the trip from free status in 0.5 second and then accelerate or decelerate to
preset frequency. (Except for momentary power loss, please refer to Fn_31/32 for details).
3. When Fn_35>0, Fn34>0: The inverter will free run for a certain period (ser by Fn_34) and
then accelerate or decelerate from Fn_42 to preset frequency. (Except for momentary power
loss, please refer to Fn_31/32 for details)
4. The number of Auto Restarts will be reset under the following conditions:
(1). Fault is not detected for 10 minutes (either in Run or Stop Mode).

Note:
An IGBT type T-verter can provide a lower audible motor noise using a higher carrier frequency.
However, a drive with to high of a carrier frequency may lead to interference in other electronic
equipment. It’s recommended that a carrier frequency of not more than 10 or 12 kHz be used for
protection of the motor and surrounding equipment that may be sensitive to high carriers.
42
Fn_44: Stopping Mode and Braking Resistor Protection
Note:
If the (Fn_44) is set at free run to stop, the T-verter will cut off the output after receiving a stop
instruction and the motor will coast to a stop.
If the (Fn_44) is set for deceleration to stop, the T-verter will decelerate to the frequency set by
(Fn_54) after receiving deceleration instructions, the output voltage level set at (Fn_55) the
T-verter will stop after the time period set by (Fn_53)
If the (Fn_44) is set for protection of the Built-in braking transistor, and operation of drive is too
frequently decelerate, the braking transistor and braking resistor may overheat and T-verter will
trip. OH1 will show this on Keypad display. The T-verter can be manually restarted after the
braking resistor has cooled off. If the braking resistor is damaged and leads to OV-C trip,
deceleration time must be increased or the external braking resistor replaced.
43
Fn_48: Dynamic Braking, Priority Stopping, Speed Search and AVR Control
Note:
1. When selecting (Fn_48) for enhanced braking capacity, the inertia of the load can be
absorbed by using the output voltage adjustment for deceleration.
2. When selecting (Fn_48) for stop Key effective in remote control, the “STOP” key on
Keypad can be used for emergency stopping even when using the terminal 2 for remote
control operation. (Stopping mode set by Fn_44) The External switch must be turned OFF
and ON again to re-start the T-verter.
3. When selecting (Fn_48) Speed Search from Terminal 2, the Speed search will be effective
if the multi-function inputs are used (Fn_56) (Fn-57) (Fn_58) (Fn_59) (Fn_60) otherwise,

Note:
During operational conditions where the motor must run at low speeds, its important to pay
attention to the motors capacity to dissipate heat, since most motors are designed to cool them
selves at 60 Hz and full voltage, proper setup of the thermal functions should be observed.
When the electronic thermal motor protection is on in (Fn_69) during an overload condition, the
T-verter will continue running and while displaying “OL1” the blinking of the OL1 will continue
until the running current is lower than 103% or 113% (depending on the setting in (Fn_69).
The T-verter will continue to run when the current is under 110%; if the T-verter continues above
110% the T-verter will time out proportionally to 150% at one minute.
In (Fn_71) if the setting is (xxx0) after the electronic thermal T-verter protection is energized, the
T-verter Base Block immediately shuts down the drive and starts to display “OL2”.
To re-start the T-verter, it is necessary to press the RESET key
In (Fn_71) if the setting is (xxx1) after the electronic thermal T-verter protection is energized, the
T-verter will continue to run and display a blinking “OL2” until the current is lower than 110% of

1. Definition of the over torque feature: the output current (rated current is 100%) remains above
over torque detection level (Fn_78) during over torque detection time (Fn_79).
2. (Fn_77) is set to (x0xx) When over torque occurs, the T-verter continues running and display
the blinking “OL3” light until the output current is lower than the (Fn_78) setting.
(Fn_77) is set to (x1xx) When over torque occurs, the T-verters base blocks immediately and
the display blinks “OL3”. To re-start the drive, it is necessary to press RESET key.
3. When (Fn_61) (Fn_62) or (Fn63) (multi-function output terminal control) is set to 05, the
multi-function output provides an over torque detection signal. The over torque detection
output signal is available only if (Fn_77) is set to (xxx1)

1. This function can be applied to Fans or Pumps that have loads with high starting inertia. In
these types of applications where the load is heavy during start-up but tapers off to a variable
torque type load at some point in the ramp curve, using function (Fn_83) to adjust the suitable
gain (voltage level) at the target speed will reduce the V/Hz ratio saving energy.
2. The Energy saving function is available only if (Fn_56) (Fn_57) or (Fn_58) (multi-function
input) are set to (08) or (24).
3. When (Fn_82) is set to (xx01) and (Fn_56) (Fn_57) or (Fn_58) are set to (08) When the
multi-function input terminal is turned ON, the output voltage will decrease gradually to the
previous output voltage x (Fn_83). When the input terminal is turned off, the output voltage
will increase to the previous voltage gradually.

Remark:
The speed of above mentioned voltage ramps up and down is the same manner as is does when
using speed search.
Note:
1. When Fn_84=xxx0, T-verter will be operate under multi-speed frequency when Fn_56~Fn_58
is set to 0~2 and multi-function input terminal is on.

2. If Fn_84=xxx1, Fn_56~Fn_58=0~2 or 16~18 and pulse signal is received on multi-function
input, T-verter will run at a certain to time (set by Fn_85~Fn_91) at a certain frequency *set by
Fn_17~Fn_23) then return to frequency set by keypad or external VR or(Fn_84=xx0x) or jump
back to zero speed(Fn_84=xx1x).
Note:
1. Adjusting (Fn_92) (unit: 2ms) to 1/4 of machine‘s vibration cycle can provide the optimal
performance.
2. Adjusting (Fn_93) according to the amplitude of vibration can reduce vibration to a minimum.

Maintenance Section:
This T-verter requires almost no routine checks. It will function efficiently and its normal
operation lifetime will be longer if it is kept clean, cool and dry.
Especially check for tightness of electrical connections, discoloration or other signs of
over-heating. During service inspection, turn off the AC main circuit power and wait for the
charging indicator LED 101 to extinguish ( or at least 10 minutes) before touching any circuit
components. Failure to adhere to this warning could result in serious or lethal injuries.

COMPATIBILITY (EMC) filters:
Today all modern PWM variable speed drives, use fast switching power devices to achieve
high efficiency and reduce motor noise. This results in electromagnetic interference (EMI)
and radio frequency interference (RFI). For operational reasons the interference may need
to be suppressed.
EC DIRECTIVES
This T-verter is able to comply with the EC Directives 89/336/EEC on limits to EMI and
RFI with the use of an optional filter. Independent testing has demonstrated compliance to
the following standards when the optional filters are used.
EMI Emission
EN61800-3, +A11: First Env. (ClassB) Table9,10.
Second Env. (ClassA) Table11,12.
200 Volt Class 2P5 ~ 203 are compliant with class B filters
400 Volt Class 401 ~ 405 are compliant with class B filters

ADDITIONAL PRECAUTIONS TO LIMIT EMI AND RFI
Earth
For T-verters:
In any single low-impedance earth point or where busbar is required in order to put to earth
directly or independently for varied circuit. The T-verter itself must be put to earth
independently. No other equipment should share the earth connection of the T-verter
(except the motor). All circuits have to be connected to external earth through copper bars.
Note: The system needs to be checked from time to time to ensure well connection to earth
ground
Shielding:
2.1 The T-verter will emit EMI noise via the connection cable; therefore, all motor cables,
control cables and signal cables must be shielded unless the length of the cable is less than 1
meter.
2.2 The shielded motor cable must be put to the earth ground on both ends, the shorter the cable
the better to reduce the stray inductance and capacitance effect.
68
3. Segregation
3.1 All signal cable and control cable must be separated from un-shielded or protected motor
cable and unfiltered power lines. The distance should be more than 30 cm. The control
cable and power cables should be put perfectly vertically when those two cable have to cross
each other.
WARNNING
EMI filter can be used only in 3 phase supplies, which are nominally balanced with respect to
earth. Never apply EMI filter in a grounded delta supply system.
