Servo Systems

Servo systems are motion systems made up of a servo motor, servo drive and feedback elements that regulate the position, speed and torque of the motor shaft in a closed loop using encoder feedback. They are used in applications requiring precise positioning and fast acceleration, such as CNC machines, packaging and labeling machines, robot axes, and cutting and winding lines. The subcategories include servo motors, servo drives, servo kits offering motor and drive together, and external rotary encoders; ratings such as 100 W, 400 W, 750 W, 1 kW and 3 kW are available in Delta Electronics, Schneider Electric Lexium and GMT products. Select the motor torque and power according to the inertia and speed profile of the load, the drive according to the motor and the mains voltage, the command interface (pulse, EtherCAT or CANopen) according to your PLC or motion controller, and the need for a brake according to whether the axis is vertical or horizontal. The motor and drive should be taken from matching series of the same manufacturer. Motor power and encoder cables are listed in the Servo Motor Cables category under Cables.

How to choose Servo Systems

Servo systems are motion systems made up of a servo motor, servo drive and feedback elements that regulate the position, speed and torque of the motor shaft in a closed loop using encoder feedback. They are used in applications requiring precise positioning and fast acceleration, such as CNC machines, packaging and labeling machines, robot axes, and cutting and winding lines.

  • Separate sensing, motion control, logic processing and operator interface requirements.
  • Select signal type, supply voltage, communication protocol and I/O count for the machine network.
  • Verify housing size, sensing distance and PNP/NPN output polarity against the PLC input card.
