Over-voltage at stop (ovS)
Power voltage is too high - Check if the input voltage is within the rated AC motor drive input voltage range, and check for possible voltage spikes.
Check the wiring of brake resistor or brake unit.
Reset only when DC bus voltage is lower than 90% of the over-voltage level.
