OV1: Overvoltage occurs during acceleration 1. Use a multimeter to detect whether the input power supply voltage is abnormal. 2. Check if the motor is grounded and try to change the grounding status (remove the ground wire if it is grounded in present; If it is not grounded in present, try to ground the motor) Find quick answers in the Shihlin Electric FAQ—selection, wiring and troubleshooting for circuit breakers, magnetic contactors, AC drives, servo, HMI and PLC control.
