Code
Fault
Cause
Solution
fault
synchronous motors not set properly;
The autotune parameter is not right;
The VFD is not connected to the
motor
normal;
Check whether the control
parameter is set properly or not;
Increase the maladjustment
detection time
LL
Electronic
underload fault
The VFD will report the underload
pre-alarm according to the set value.
Check the load and the underload
pre-alarm point.
ENC1O
Encoder offline
fault
Closed loop vector control, the
encoder signal is offline;
Encoder damage
Check the wiring of the encoder
and reconnect;
Check whether the encoder has
output or not
ENC1D
Encoder reverse
fault
Closed loop vector control, the
encoder is not connected or damaged
or the wiring of the VFD is incorrect.
Check the wiring of the encoder
and adjust wiring.
ENC1Z
Encoder Z pulse
offline fault
Closed loop vector control, Z pulse
signal of the encoder is offline;
Encoder damage
Check the wiring of the encoder
and reconnect;
Check whether the encoder has
output or not
Ot
Motor
overtemperature
fault
The motor runs at overload for a long
time or the motor is abnormal;
The temperature detection resistor is
abnormal;
The motor overtemperature protection
is set improperly
Detect and maintain the motor;
Check whether the temperature
sensor is normal or not;
Reset motor overtemperature
protection point
SCE
SCR fault
SCR damage;
SCR drive board damage;
SCR drive cable is connected
reversely
Change SCR and drive board;
Change the drive cable
