Product Details
The STM86 series integrated stepper motor is a high-performance, low-power stepper product independently developed by NiMotion. Based on the excellent closed-loop control system and the integrated design concept, this product integrates the stepper motor, encoder, driver and digital I/O into one, supports communication bus control, and has the characteristics of compact structure and simple wiring.
Product Features
Highly integrated design
Integrates Stepper motors, encoders, drives and digital I/O 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.
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 10-60VDC, 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.
