Starting time is too
long
The load is too heavy
The code is set incorrectly
Check
whether the motor
specification is abnormal
Please reduce the load
Please set FO (starting voltage), F5 (starting current limit) F1
(soft starting time)
Please check specification instruction and nameplate
Starting time is too
short
The load is too light
The starting time is too short
When the load is light, the starting time is often less than the set
value, and the starting balance belongs to the normal setting
code F1 starting time (current mode is invalid)
Stop suddenly
during operation
Check the external input terminals
Check whether the connection of 07 and 10 terminals are loose
Check whether the connection line of external stop button is
loose.
Abnormal
phenomenon
Content of inspection Countermeasures
The motor has hum
No starting signal but
the motor is starting
●The SCR is short-circuited and broken
through
●The starting button is abnormal
Check and replace
Check and correct the reasons of faults
The motor sounds
abnormal during start-
up and operation
●Motor phase loss
Try different time to reduce the voltage (several
adjustments may be necessary to obtain ideal results)
If you use external
control to start, the
motor cannot start
●The control connection is incorrect
●Start and stop signals are sent at the
same time
Check the connection of start and stop
Check whether the start and stop signals are sent at
the same time
Check whether the keyboard is in the local control
menu
Check whether the parameter neutral control is not
activated
When bus
communication is
used to input starting
information,
the
motor will not start
●The keyboard is in the local control
menu
●Bus parameter setting error
Check whether bus control is activated
Check whether it is allowed to use
Check whether the programmable input is set correctly
6.3 Fault codes and solutions
Display and description Problems and solutions
Error00
The fault has been solved
Faults such as under-voltage, over-voltage, or overheating has just occurred, and it is
now normal, and the motor can be started after reset
Error01
External instantaneous stop
terminal open circuit
Short-circuit the external control instantaneous stop terminal
⑦
and the common terminal
10, or connect it to the normally closed contact of other protection devices.
Error02
Soft starter overheated
Starting too frequently or the power of the motor does not match the soft starter
