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
terminal
⑦
and public terminal
⑩
, or connecting to other protective
devices normally closed contact.
Err02
Soft starter
overheating 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 whther 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 P6, PP parameters
set incorrectly.
Err09
Supply voltage is
too low Check the input voltage or setting item P7 parameter set
incorrectly.
Err10
Supply voltage is
too high Check the input voltage or setting item P8 parameter set
incorrectly.
Err11
Set the parameters
error 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 underload 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.
