DuoServoSystem

DuoServoSystem is a dual servo motor arrangement used to deliver precise, coordinated motion in automated equipment. It pairs two servo motors with encoders and a shared drive to control a load with high torque and accuracy. Each axis has a motor, encoder, and drive, and the motors are connected to the load by belts, gears, or a direct-drive link, allowing independent motion or tight synchronization for two-axis tasks.

Control and operation: The system runs in closed-loop mode, using encoder feedback to regulate position, velocity, and torque. A controller applies PID or advanced algorithms, often with feedforward and cross-axis synchronization to reduce errors and backlash. In master/slave configurations, one axis serves as the reference while the other follows. Many implementations include homing, calibration, fault detection, and safety features such as overcurrent and overtemperature protection.

Interfaces and applications: It supports robotics, CNC, packaging, and other precision automation where two synchronized axes or high torque in a compact package is needed. It can be a standalone module or integrated into a motion controller or PLC via protocols such as CANopen, EtherCAT, or Modbus. Variants differ in torque, encoder resolution, and form factor.

Advantages and considerations: Benefits include higher torque range, smoother motion, and improved load distribution. Design must address backlash, alignment, grounding, and thermal management. Proper commissioning involves tuning parameters, setting end stops and homing routines, and validating synchronization and safety limits.
