5) Damage caused by the fire, flood, abnormal voltage, etc;
6) Damages caused since the frequency converter is used in improper functions;
7) Related service fees shall be calculated as per the factory unified standard, if any contract is available,
handle it as the principle of contract first.
8.3 Failure alarm and measures
If failure for JAC200 series frequency converter occurs in running, the frequency converter will
immediately protect the motor and stop outputting, meanwhile, there is the contact action for the frequency
converter failure relay. The panel of the frequency converter will display the failure code. See the table
below for the details concerning the failure type and the common solutions corresponded with the failure
code. The examples listed in the table are just for references, please do not repair and modify without
permission, if the failure cannot be removed, seek technical support from our company or the product agent.

Err01
1. Short circuit for frequency
converter output circuit
2. Too long wiring between motor
and frequency converter
3. Too hot module
4.
Loose
internal
wiring
for
frequency converter
5. Abnormal main control panel
6. Abnormal drive board
7. Abnormal inverse module
1. Troubleshoot the external failure
2. Install electric reactor or output
filter
3. Inspect if the air channel is
blocked, and if fan functions normally
and then troubleshoot the existing
problems
4. Properly plug in all the connecting
lines;
5. Seek technical support;

Overcurrent
during
acceleration
Err02
1. Grounding or short circuit exist in
the output circuit of frequency
converter
2. The control mode is vector and
parameter identification is not
conducted
3. Too short acceleration time
4 Improper manual torque lifting or
V/F curve
5 Relatively low voltage
6. Start the motor which are rotating
7. Sudden load in the acceleration
process
8. Relatively small model selection
for frequency converter
1. Troubleshoot the external failure
2. Conduct the motor parameter
identification
3. Increase the acceleration time
4. Modify manual lifting torque or
V/F curve
5. Adjust the voltage to the normal
range
6. Select the rotating tracing start or
restart after the motor stops
7. Cancel sudden load
8. Choose frequency converter with
bigger power level
