Appendix 2 Alarm code list
Appendix 200
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.
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 PID parameters
3.Check all peripheral feedback devices of
the system (sensors, potentiometer) and
wirings.
Strong electromagnetic
interference
Reduce peripheral interference.
OLS
Stall prevention
and protection
1.Reduce the load
2.Increase 06-01(P.22) value.
The inverting part of IGBT
module overheated
1.Lower the surrounding temperature and
increase venting
2. Check if the cooling fan is functioning
properly
3. Confirm whether the carrier frequency
00-11 (P.72) is set too large
Input power error(phase loss)
Check if the power supply is normal.
1. Motor overload
2. The value in 06-08 (P.155)
and 06-09(P.156) doesn’t make
sense.
1.Reduce the load
2.Set 06-08 (P.155) and 06-09(P.156)
properly
1.Check the wiring
2.Check the parameter setup
3.Reduce noise interference
The terminal 3-5 analog input
disconnect
check 3-5 terminal cable connection status
GF
Output short to
ground
Shortage between output and
ground
Please check whether the motor short circuit
to ground
Note 1: Do not turn on the power repeatedly before removing the cause of the alarm.
