Appendix 2 Alarm code list
Appendix 397
Code Screen display Cause Troubleshooting
OPT
RS-485 connector
error
1.Communication error ,
exceeding the retry limit.
2. External noise interference
3. The logic of the communication
control program is unreasonable
4.Disconnect time exceeding the
limit.
1.Check whether the parameter (P.32,
P.33, P.36, P.154) setting is the same
with upper controller communication
setting
2.Check whether the RS485 DA+ and DB-
terminal wiring is correctly connected to
the upper controller
3.Check whether the communication
protocol of the upper controller is the
same as the one declared in inverter
4.The communication line is interfered by
external noise (it is recommended to use
twisted-pair shielded wire and connect to
the signal ground correctly)
5.The inverter internal communication port
is damaged and needs to be returned to
the factory for inspection
PUE
PU connector error
1.It is recommended to use twisted-pair
shielded communication lines and the
shielding layer is properly grounded
2.Check the communication program
3.Set the communication parameters
correctly
CbE
Expansion
connector error
EEP
Memory error
ROM malfunction
If the alarm repeated, send the unit back to
the dealer or the manufacturer to repair.
Avoid frequent parameters modification
and saving target frequency to EEPROM,
please refer to 07-11 (P.34) and target
frequency address H1002 to prevent
damage.
PID
PID error
1.The capacity of the inverter or
motor is not enough
2.PID target value or feedback
value doesn’t make sense
3.Peripheral devices malfunction
4.During PID control, the feedback
signal is not connected or dropped
1.Use an inverter or a motor with bigger
capacity.
2.Check the feedback gain value. Reset
the target value according to the feedback.
3.Check all peripheral feedback devices of
the system (sensors, potentiometer) and
wirings.
CPU
CPU error
Strong electromagnetic
interference
Reduce peripheral interference.
OLS
Stall prevention
and protection
Over-loaded motor
1.Reduce the load
2.Increase 06-01(P.22) value.
