Motor
overload
OL1
1: P9.01 is set improperly.
2: The load is too high or
another motor is connected to
the motor.
3: The AC inverter model is of
too small power class.
1: Set P9.01 correctly.
2: Reduce the load and check
the motor and the mechanical
condition.
3: Select an inverter of higher
power class.
