Overcurrent at
constant speed
OC2
1: The output circuit is
grounded or short circuited.
2: Motor auto-tuning is not
performed.
3: The deceleration time is
too short.
4: The voltage is too low.
5: A sudden load is added
during deceleration.
6: The braking unit and
braking resistor are not
installed.
1: Eliminate external faults.
2: Perform the motor auto-
tuning.
3: Increase the deceleration
time.
4: Adjust the voltage to normal
range.
5: Remove the added load.
6: Install the braking unit and
braking resistor.
Overcurrent at
constant speed
OC3
1: The output circuit is
grounded or short circuited.
2: Motor auto-tuning is not
performed.
3: The voltage is too low.
