Grounding Warning 1. For grounding actuator, connect the copper wire of the actuator to the driver’s protective earth (PE) terminal and connect the copper wire of the driver to the earth via the control panel’s protective earth (PE) terminal. Do not connect them directly to the control panel’s protective earth (PE) terminal. 2. In the unlikely event that malfunction is caused by the ground, it may be disconnected. Driver Control panel PE terminal Actuator Maintenance Warning 1. Perform maintenance checks periodically. Confirm wiring and screws are not loose. Loose screws or wires may cause unexpected malfunction. 2. Conduct an appropriate functional inspection and test after completed maintenance. In case of any abnormalities (if the actuator does not move or the equipment does not operate properly, etc.), stop the operation of the system. Otherwise, unexpected malfunction may occur and safety cannot be assured. Conduct a test of the emergency stop to confirm the safety of the equipment. 3. Do not disassemble, modify or repair the driver or its peripheral devices. 4. Do not put anything conductive or flammable inside the driver. Otherwise, fire can result. 5. Do not conduct an insulation resistance test or insulation withstand voltage test. 6. Reserve sufficient space for maintenance. Design the system so that it allows required space for maintenance. Power Supply Caution 1. Use a power supply with low noise between lines and between power and ground. In cases where noise is high, use an isolation transformer. 2. Take appropriate measures to prevent surges from lightning. Ground the surge absorber for lightning separately from the grounding of the driver and its peripheral devices. Wiring Warning 1. The driver will be damaged if a commercial power supply (100V/200V) is added to the driver , s servo motor power (U, V, W). Be sure to check wiring such as wiring mistakes when the power supply is turned on. 2. Connect the ends of the U, V, W wires from the motor cable correctly to the phases (U, V, W) of the servo motor power. If these wires do not match up, it is unable to control the servo motor.
