This function allows the prohibition or “jumping” of critical frequencies so

that the motor can operate without resonance caused by machine systems.

This function is also used for dead band control. Setting the value to 0.0Hz

disables this function.

Set prohibited frequency 1 or 2 as follows :

Operation is prohibited within jump frequency range.

However, motor operates without jumping during accel/decel.

Sets the inverter to restart and reset fault detection after a fault occurs.

The number of self-diagnosis and retry attempts can be set at n48 up to 10.

The inverter automatically restarts after the following faults occur :

OC (overcurrent)

GF (ground fault)

OV (overvoltage)

The number of retry attempts are cleared to 0 in the following cases :

(1) If no other fault occurs within 10 minutes after retry

(2) When the fault reset signal is ON after the fault is detected

(3) Power supply is turned OFF
