Servo Drive

Connecting a servo drive involves a few key steps, typically for industrial or larger-scale servo motor control. Here's a general guide by Darwin Motion (VFD & Servo Drive Manufacturer)

Power Supply: Servo drives often require a separate power supply unit (PSU) to provide power to the servo motor. Determine the voltage and current requirements of your servo drive and motor system. Make sure your power supply can meet these specifications. You can check out solar drive price for more details.


Connect the positive and negative terminals of the power supply to the corresponding terminals on the servo drive. Ensure correct polarity.

Connect the power output terminals of the servo drive to the corresponding terminals on the servo motor. Again, ensure correct polarity.

Feedback Device Connection (Optional): Many servo drives support feedback devices like encoders or resolvers for precise motion control. If your servo motor setup includes a feedback device, connect it to the appropriate terminals on the servo drive according to the manufacturer's instructions.

Control Signals:

Connect the command signal wires from your motion controller or PLC (Programmable Logic Controller) to the appropriate terminals on the servo drive. These signals typically include velocity command, torque command, and position command signals.

Connect any other control signals required for your specific application, such as enable signals or fault monitoring signals.

Grounding: Ensure proper grounding by connecting the ground terminals of the power supply, servo drive, and other components to a common ground point. This helps prevent electrical noise and interference.

Configuration and Tuning: Follow the manufacturer's instructions to configure and tune the servo drive parameters for your specific application. This may involve setting motor parameters, adjusting PID control gains, and configuring motion profiles.

Testing and Commissioning: Once the servo drive is connected and configured, perform thorough testing to ensure proper operation. Verify that the motor responds correctly to command signals and achieves the desired motion profiles.

Safety Precautions: Always follow appropriate safety procedures when working with servo drives and high-power electrical systems. Make sure to de-energize the system before making any connections or adjustments, and follow all relevant safety guidelines and regulations.

Remember to consult the user manual and documentation provided by the manufacturer of your servo drive manufacturers for detailed instructions specific to your model. Improper wiring or configuration can lead to damage to the equipment or unsafe operation.
