maxon EPOS4 Compact 50/15 CAN

maxon EPOS4 Compact 50/15 is a compact programmable positioning controller for brushless and brushed DC motors with encoders, designed for applications requiring precise position, velocity and torque control.

Drives motors up to 750 W at 15 A continuous and 50 A peak. Input 10–50 V DC. Operating modes CSP/CSV/CST (Cyclic Synchronous Position/Velocity/Torque), Profile Position/Velocity/Torque, Homing and Interpolated Position.

Supports incremental, absolute SSI/BiSS-C, Hall encoders and combinations. CANopen (CiA 402) or EtherCAT (CoE) communication. Configured via EPOS Studio (Windows). Used in humanoid robotics (e.g. Suitable Technologies BeamPro, Sarcos Guardian XO), AGV and precision positioning stages.

Market class

Motion Controllers is a subcategory of electronic and embedded components responsible for controlling the motion of robots and their subsystems. It encompasses axis controllers, drive controllers, and circuits for trajectory management and motion synchronization. In robotics, these modules are essential for precise positioning, multi-axis control, and safe operation of actuator systems.

Component type covering ESC controllers used to control electric motors in robotics, automation, and motion control systems.

A class of drive controller designs that use FOC for precise control of motor torque, speed, and position.
