• Even after the recovery from an input power failure, the motor continues deceleration stop. If the DC voltage 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 undervoltage (
moff
) level at operation deceleration stop
during power failure, the motor will coast and inverter displays
stop

alternately. The motor continues
coasting even after power supply is restored.
