Chapter 9 Fault causes and treatment
Fault codes and treatment as following table:
Display
Description
Problems and treatment methods
Err00
Failure has been
solved
Just happened undervoltage, overvoltage or overheating,
instantaneous stop terminals are open, such failures, now has
been normal, this time to prepare lights, reset to start the motor.
Err01
External terminal
momentary
Open circuit
Short-circuit connection with the external Instantaneous stop
terminal⑦and public terminal⑩, or connecting to other
protective devices normally closed contact.
Err02
Soft starter over-
heat
Start too often or the motor power do not match with the soft
starter.
Err03
Starting times too
longer than 60
seconds
Starting parameter settings is inadequate or the load is too
heavy, the power capacity is not enough, etc.
Err04
Input phase lost
Check the input or main circuit failure, whether the bypass
contactor is stuck in the closed position and whether the SCR is
in open circuit and so on.
Err05
Output phase lost
Check the input or main circuit failure, whether the bypass
contactor is stuck in the closed position and whether the SCR is
in open circuit and so on.
Err06
Three-phase
unbalanced
Check whether the input three-phase power supply and the load
motor is normal.
Err07
Start over-current
Whether the load is too heavy or motor power does not match
with soft starter.
Err08
Running overload
protection
Whether the load is too heavy or setting items P7, PP
parameters set incorrectly.
Err09
Supply voltage is
too low
Check the input voltage or setting item P9 parameter set
incorrectly.
Err10
Supply voltage is
too high
Check the input voltage or setting item PA parameter set
incorrectly.
Err11
Incorrect parameter
Setting
Modify the settings, or pressing the Enter key on power to
restore the factory values.
Err12
Load short-circuit
Check whether overloading or thyristor short circuit.
Err13
Automatic re-start
wiring error
Check whether the outside the control start and stop terminal is
connected to 2-wire mode.
Err14
External Stop
terminal wiring
error
When you allow external control mode, the external control
stop terminal is in the open state, which can not start the motor.
Err15
Motor under-load
Check the motor shaft and load faults.
Note: Some fault phenomena are interrelated, as the report Err02, may be related with soft
starter overheating or load short current, so when checking fails, consideration should be
comprehensive, accurately determine the point of failure.
