Appendix 2 Alarm code list
APPENDIX 398
Code
Screen display
Cause Troubleshooting
SCP
Short circuit/
over-current
1.Short circuit at output-end
2.Inverter false alarm SCP
1.Check if the output circuit is short and
check the wiring
2.Inverter may be interfered by external
electromagnetic noise, please improve the
wiring
(Note 1)
NTC
Module overheat
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
NTC2
Module 2 overheat
NTC3
Module 3 overheat
NTC4
Module 4 overheat
NTC5
Module 5 overheat
NTC6
Module 6 overheat
NTC7
Electrolytic
capacitor overheat
The surrounding of the capacitor is
overheat
NTC8
Starting resistor
overheat
The relay in the rectifying part
don’t actuate which leads to
resistor overheat
Check the relay in the rectifying part of the
inverter.
OL2
Torque overload
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
BE
Brake transistor
error (Relay error)
Brake transistor error（Relay error）
Send the unit back to the dealer or the
manufacturer to repair
IPF
Input power error
Input power error Check if the power supply is normal.
CPR
CPU error
CPU error
1.Check the wiring
2.Check the parameter setup
3.Reduce noise interference
AEr
Terminal 4-5/3-5
error
The terminal 4-5-3-5 analog
output disconnect Check parameter 02-24
(P.184),02-33(P.545)
