6.1 Faults and solutions
The PE6000 provides a total of 24 pieces of fault information and protective functions. After a
fault occurs, the AC drive implements the protection function, AC drive output stops, and displays
the fault code on the operation panel. Before seeking for technical support, you can first determine
the fault type, analyze the causes, and perform troubleshooting according to the following tables. If
the fault cannot be rectified, contact the agent or our company.
Err22 mentioned below is the AC drive hardware overcurrent or overvoltage signal. In most
situations, hardware overvoltage fault causes Err22.

Possible Causes
1: The output circuit is short
circuited.
2: The connecting cable of the
motor and the AC drive is too
long.
Err01
3: The module overheats.
4: The internal connections
become loose.
5:The main control board is faulty.
6: The drive board is faulty.
7: The inverter module is faulty.
1: The output circuit is grounded
or short circuited.
2: vector control is presented and
Motor auto-tuning is not
performed.
3: The acceleration time is too
short.
4: Manual torque boost or V/F

curve is not appropriate.
5: The voltage is too low. 6: The
startup operation is
performed on the rotating motor.
7: A sudden load is added during
acceleration.
8: The AC drive model is of too
small power class.
1: Eliminate external faults.
2: Install a reactor or an
output filter.
3: Check the air filter and the
cooling fan and troubleshoot
existing problems
4: Connect all cables
properly.
5: Seek for technical support
6: Seek for technical support
7: Seek for technical support
1: Eliminate external faults.
2: Perform the motor auto-
tuning.
3: Increase the acceleration
time.
4: Adjust the manual torque
boost or V/F curve.
5: Adjust the voltage to
normal range.
6: Select rotational speed
tracking restart or start the
motor after it stops.
7: Remove the added load.
8: Select an AC drive of
higher power class.
