Possible cause
Solution
Overcurrent
during
acceleration
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.
4: A sudden load is added
during operation.
5: The inverter model has a
too low power class.
1: Eliminate external faults.
2: Perform the motor auto-
tuning.
3: Adjust the voltage to
normal range.
4: Remove the added load.
5: Select an inverter of higher
power class.
Overvoltage
during
acceleration
OU1
1: The input voltage is too
high.
2: An external force drives the
motor during acceleration.
3: The acceleration time is too
short.
4: The braking unit and
braking resistor are not
installed.
1: Adjust the voltage to
normal range.
2: Cancel the external force or
install a braking resistor.
3: Increase the acceleration
time.
4: Install the braking unit and
braking resistor.
