Product Details
The STM57H-B series (open-loop & closed-loop) integrated stepper motor is a step product independently developed by NiMotion. Based on the excellent closed-loop control system (closed-loop mode) and highly integrated design concept, this product integrates the stepper motor, encoder (closed-loop), driver, digital IO and brake, supports communication bus control, and has the characteristics of compact structure and simple wiring.
Product Features
Highly integrated design
All-in-one design deeply integrating the motor body with the drive and encoder, giving a compact body, simple wiring and easier machine integration.
High Precision Encoder Feedback
Built-in 14-bit high-resolution absolute encoder (closed-loop support) provides real-time position and speed feedback for more accurate closed-loop control, ensuring smoother operation and more accurate positioning.
Multi-bus communication support
Supports CANopen 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 and velocity mode, ensuring compatibility with mainstream fieldbus motion-control architectures and making replacement and commissioning easier.
Wide Voltage Input
Wide input voltage range of 12-52 VDC, suitable for various power-supply environments and giving greater flexibility in system integration and retrofitting.
Segment can be set
Micro-stepping setting of 1、2、4、8、16 steps selectable effectively reduces low-speed vibration and noise and improves positioning resolution and smoothness.

FAQ
With an incremental encoder driver, the actual position value is not retained after power‑off; a homing routine is required on each startup. A single‑turn absolute encoder retains the position without a battery (but if the shaft rotates more than half a turn after power‑off, the position is lost). A multi‑turn absolute encoder retains the position without a battery (but if the shaft rotates more than 2048 turns after power‑off, the position is lost).
