Possible cause
① Inverter outputs short circuit or
earthing.
② Instant over current of inverter
③Too high environment temperature
④Air flue is blocked or fan is
damaged
⑤DC auxiliary power supply occurs
fault
⑥ Abnormal controlpanel
① Too high environment temperature
② Fan is damaged
③ Flue is blocked
① Too high torque boost or unsuitable
V/F curve
② Too short accelerating time
③ Too large load
①Too high torque boost or unsuitable
V/F curve
② Too low main voltage
③Locked rotor of motor or too large
abrupt change of load
④Incorrect setting of motor overload
protection factor
①Fault input terminal of peripheral
equipment is close
① Improper setting of baud rate
② False of serial port communication
③ Without upper machine
communication signal
① The current detecting device is
damaged or the circuit occurs fault
②DC auxiliary power is damaged
①The circuit connecting keyboard
and control panel occurs fault
② The terminal is poor in connecting

Solution
① Examine the connecting
wire;
② Refer to solution against over
current
③Clean the air flue or change
the fan；
④Ask for service from
manufacturer or agency.
① Lower environment
temperature
② Change the fan
③ Clean the flue and change
the ventilation condition;
①Reduce the torque boost and
adjust the V/F curve.
② Extend accelerating time
③Reduce load or choose the
inverter of large power
① Reduce the torque boost
value or adjust the V/F curve.
② Examine main voltage
③ Examine load
④Set the motor overload
protection factor correctly
①Disconnect the terminal input
and remove the fault.
① Set baud rate correctly
②Examine communication
cable and ask for service
③Check whether PC works and
the connection is correct.
①Ask for service from
manufacturer or agency.
②Ask for service from
manufacturer or agency.
① Ask for service
② Examine and reconnect
