Step 1 / 6
Check the power supply's alarm history. If an 'Auxiliary regeneration frequency over' (Warning E8) occurs just before the overvoltage alarm, excessive instantaneous regenerative energy is the cause. Limit this by modifying the operation program to prevent multiple axes from decelerating simultaneously. Wait at least 5 minutes for the bus voltage to drop before resetting.
