  • IP65 protection class

  • (Optional) Built-in 17-bit single-turn/multi-turn absolute encoder

  • EtherCAT Version

Highly integrated design

Integrates Stepper Motors, Single/Multi-turn Absolute Encoders, Drives and Digital IO into a single compact unit, so no external drive is required. Compared with conventional separated solutions it saves considerable installation space, needs less wiring, and makes commissioning and maintenance easier.

Advanced Drive Algorithm

Adopts FOC (field-oriented control) and SVPWM for smooth torque output, excellent low-speed performance and lower operating noise and vibration.

High Precision Encoder Feedback

Built-in B: 17-bit single-cycle absolute encoder/D: 17-bit multi-cycle absolute encoder provides real-time position and speed feedback for more accurate closed-loop control; multi-turn absolute counting and automatic position storage on power loss mean no re-homing is needed after power-up.

Multi-bus communication support

Supports EtherCAT, CANopen and RS485 communication, allowing quick connection to mainstream PLCs, motion controllers and host systems, with flexible networking and easy expansion.

Standard CiA 402 Sport Mode

Supports CiA 402 standard motion modes (PP, PV, HM, CSP, CSV, etc.) as well as position mode, velocity mode and torque mode, ensuring compatibility with mainstream fieldbus motion-control architectures and making replacement and commissioning easier.

Wide Voltage Input

Wide input voltage range of 16-52 VDC, suitable for various power-supply environments and giving greater flexibility in system integration and retrofitting.
