Over-voltage at stop

Check if the input voltage is within the rated AC motor drive input voltage range,
and check for possible voltage spikes.

f the phase-in capacitor or active power supply unit activates in the same power
system, the input voltage may surge abnormally in a short time. In this case,
install an AC reactor.

Check the wiring of the brake resistor or braking unit.
