[If momentary power failure occurs]
An example of setting when f302=2
• Even after the recovery from an input power failure, the motor continues deceleration stop. If the voltage in the
inverter main circuit falls below a certain level, however, control will be stopped and the motor will coast.
• If the voltage in main circuit falls below main circuit under voltage (moff) level at the deceleration stop operation
during power failure, the motor will coast and inverter displays stop and 0.0 alternately. The motor continues
coasting even after power supply is restored.
