IP65 protection class
Built-in 17-bit single-turn absolute encoder
Highly integrated design
Integrates Stepper Motors, Single-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 17-bit single-turn absolute encoder
provides real-time position and speed feedback for more accurate closed-loop control; automatic position storage on power loss mean no re-homing is needed after power-up.
Multi-bus communication support
SupportsCANopen 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 16-72 VDC, suitable for various power-supply environments and giving greater flexibility in system integration and retrofitting.
