Chapter 6 Troubleshooting
PI500 can provide effective protection when the equipment performance is played fully. The
following faults may appear in the process of use, please refer to the following table to analyze the
possible causes and then trouble shoot.
In case of damage to the equipment and the reasons that can not solved, please contact with your
local dealers/agents, or directly contact with the manufacturers to seek solutions.
6-1.Fault alarm and countermeasures
PI500 can provide effective protection when the equipment performance is played fully. In case
of abnormal fault, the protection function will be invoked, the inverter will stop output, and the faulty
relay contact of the inverter will start, and the fault code will be displayed on the display panel of the
inverter. Before consulting the service department, user can perform self-check , analyze the fault
cause and find out the solution according to the instructions of this chapter. If the fault is caused by
the reasons as described in the dotted frame, please consult the agents of inverter or directly contact
with our company.

Possible causes
Solutions
1
Err.01
Inverter unit
protection
1.the short circuit of inverter
output happens
2.the wiring for the motor
and the inverter is too long
3.module overheating
4.the internal wiring of
inverter is loose
5.the main control panel is
abnormal
6.the drive panel is abnormal.
7.the inverter module is
abnormal
1.eliminate peripheral faults
2.additionally install the reactor
or the output filter
3.check the air duct is blocked or
not and the fan is working
normally or not, and eliminate
problems
4.correctly plug all cables
5.seek for technical support
2
Err.02
Acceleration
overcurrent
1.the acceleration time is too
short
2.manual torque boost or V/F
curve is not suitable
3.the voltage is low
4.the short-circuit or earthing
of inverter output happens
5.the control mode is vector
and without identification of
parameters
6.the motor that is rotating is
started unexpectedly.
7.suddenly increase the load in
the process of acceleration.
8.the type selection of inverter
is small
1.increase acceleration time
2.adjust manual torque boost or
V/F curve
3.set the voltage to the normal
range
4.eliminate peripheral faults
5.perform identification for the
motor parameters
6.select Speed Tracking Start or
restart after stopping the motor.
7.cancel the sudden load
8.choose the inverter with large
power level
3
Err.03
Deceleration
overcurrent
1.the short-circuit or earthing
of inverter output happens
2.the control mode is vector
and without identification of
parameters
1.eliminate peripheral faults
2.perform identification for the
motor parameters
3.increase the deceleration time
4.set the voltage to the normal
