Possible Cause Solution
Fault Type
Short circuit to
ground
E23.00
The motor is short circuited
to the ground.
Check the motor cables and motor for short circuit to
ground.
Axis fault
E23.01
A hardware overcurrent fault
occurs during short-to-
ground detection upon
power-on.
E23.02
A hardware overvoltage fault
occurs during short-to-
ground detection upon
power-on.
E23.03
A great risk is detected
during short-to-ground
detection upon power-on.
E23.04
A lower bridge overcurrent
fault occurs during short-to-
ground detection before
startup.
E23.05
A bus overcurrent fault
occurs during short-to-
ground detection before
startup.
E23.06
A lower bridge and bus
overcurrent fault occurs
during short-to-ground
detection before startup.
Power supply unit
fault
E25.00
The power supply unit is
faulty.
Eliminate the power supply unit faults, such as input
phase loss and overtemperature.
Check the terminal configuration of the power supply
unit. If any one of the following functions is selected,
a fault is reported when there is no feedback signal:
1: Operation enable
2: Incoming circuit breaker feedback
3: Auxiliary circuit breaker feedback
4: Residual current device feedback
If any one of the following functions is selected, a
fault is reported when the terminal is active:
6: Drive unit running prohibited
7: Drive unit coast-to-stop
8: Drive unit stop according to the preset mode
Axis fault
Accumulative
running time reach
E26.00
The accumulative running
time reaches the reference.
Clear the record through parameter initialization.
