Integrated Design Philosophy
Highly integrated design
Integrates Stepper motors, 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.
High Precision Encoder Feedback
Built-in 17-bit encoder (multi-turn absolute counting, automatic storage of power loss) 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 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 16~72 VDC, suitable for various power-supply environments and giving greater flexibility in system integration and retrofitting.
Complete diagnosis and protection
Comprehensive diagnostics and protection covering over-voltage, under-voltage, over-temperature, stall, overload, over-speed, over-travel and homing timeout, with current and historical alarm records for safer operation.
Application in Pick-and-Place Machines
This integrated 86-series stepper servo motor series is suitable for small and medium-sized automation equipment, controlling lifting platforms and XY-axis movement. Its compact integrated design saves equipment space, and the motor requires no external driver, reducing external components. The built-in encoder enables full closed-loop control. It supports multiple communication protocols for easy installation and use.
