Fault and alarm are abnormal working status of inverter.But
there are obvious differences between them.
When the Inverter is running for self-monitoring state. If
fault issued ， fault code of inverter will be displayed ， and the
inverter output will be shut down ， it results in the motor in a
free-running state until stopping ； If alarm issued, alarm code of
inverter will be displayed, the inverter output will be not shut down,
and the motor is still controlled by the inverter.

Fault reset of inverter has many ways: operate the "reset
key" of keyboard、terminal reset function, or, if necessary, shut off
the main power supply for some time can make fault reset. If the

fault has disappeared, inverter will resume normal operation; if the
fault still exists, inverter will be tripped again.
Notice: If the jump-start command is effective, fault reset
will jump-start transmission equipment.

6.3 Common Faults and Solutions

Inverter may have following faults or malfunctions during
operation, reference the following solutions.
74
Installation
6.3.1 No Display after Power on:
1. Inspect if the voltage of power supply and the rated voltage
of inverter is consistent with multi-meter. If the power supply has
problem, inspect and solve it.
2. Check the CHARGE light.
3. If the above are normal, the fault may lie part of the
switching power supply. Please ask for support.
6.3.2 Motor doesn’t move after inverter running
1. If the motor has brake device, make sure that motor is
not in a brake condition.
2. Disconnect the inverter and the motor wiring, run
inverter in 50Hz ， inspect if there is balanced three-phase
output among U, V, W with multi-meter, notice: due to U, V,
W phase between is a high-frequency pulse ， please use
analog voltage meter to measure(range for AC 500V). If the
75
Installation
voltage is not balanced or no voltage, the inverter module is
damaged. Please ask for support.
3. If the above are normal. Please ask for support.

7 Maintenance
7.1 Inspect the Inverter Periodically

Many Factors such as ambient temperature, humidity, dust,
vibration, internal component aging, wear and tear will give rise to
the occurrence of potential faults. Therefore, it is necessary to
conduct routine maintenance to the inverter.

7.2 Replacement of Wearing Parts

Fans and electrolytic capacitors are wearing parts; please
make periodic replacement to ensure long term, and the ambient
temperature must be lower than 30 ℃, load rate 80% or less, run
rate of 12 hours / day cases. The replacement periods are as
follows:
1.Fan: Must be replaced when using up to 3
years;
2.Electrolytic Capacitor: Must be replaced when
using up to 5 years.

9 MODBUS Communication Protocol

This chapter describes the MODBUS communication function.
Modbus protocol supports RTU mode
9.1 MODBUS Communication Modes

MODBUS communication is made of a master station (PLC
or PC) and maximum of 31 slave stations. It communicates in
‘point to point’ master-slave mode. Master and slave
communication (serial communication) is usually the way of slave
station respond to the command after master station had
communicated. Master communicate with only one slaves each
time. Therefore, each slave station addresses to be pre-set number,
master station through the numbers with the signal communication.
It will respond to the specified command sent by the master station.
Interval between each information must be kept as below:

9.2 Information Format

MODBUS communication adopts the format that master
issue the directions and the slave to respond. The message formats
(receive/send) are shown in chart 9-2, according to the different
content of instructions (function), the length of the data also will be
changed.

Function code is used to specify the command code. Please
refer to the table below.

Chart 9- 3 Serial Communication Function Code Description
3. Data
Storage register number (the test code in numbering) and its
datas constitute a series of data. According to the contents of the
data length the instruction will change.
104
Installation
4. Check error
Using the CRC-16 (cyclic redundancy check, check sum
means) to check communication errors.
The result (Check and calculate) is stored in a data(16bit）,
its a start value of FFFFH.The data to be sent (slave address,
function code and data), a fixed value A001H put together XOR
and shift calculation. After the calculation, this data contains a
checksum value.
Check and calculation according to the following methods：
1) The start value of 16-bit data used to calculate must
be set to FFFFH.
2) Must be used starting value and slave address to do
the XOR calculation.
3) The results must be shifted to the right until the
overflow bit becomes 1.
4) When the overflow bit becomes 1, you must use the
results of step 3 or the fixed value A001H to do the XOR
105
Installation
calculation.
5) 8 times shift to calculate after (whenever the
overflow bit becomes 1, you must be carried out as described
in Step 4 to do the XOR calculation), use the results of the
previous and the next data (8-bit function code) for XOR
operation. The results of this operation must again shift eight
times, when the shift in the overflow bit is 1, the need for a
fixed value A001H XOR.
6) The data follow the same steps for processing. Deal
with the high byte first, then the low byte, until all data are
processed.
7) The result is a checksum; it contains a high byte and
low bytes.
Notice: when adding the checksum in the data frame, add the
low byte first, and then add the high bytes.

9.3.1 To Read the Contents of Storage Register
A maximum of 16 can be read out the contents of inverter
memory registers every time.
First, the directive information must contain to read out the
beginning address of the first register and the amount of register.
Response message will contain the contents of the register to be
read. Store register content is divided into high 8 bit and low 8 bit,
according to number order turn into data within a response
message.
