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 16-72VDC, 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.
Applications in Paper Folding Equipment
This integrated servo motor series is specifically designed for the high-frequency start-stop and precise fold-positioning demands of paper-folding machines. Its compact all-in-one construction saves valuable internal equipment space, allowing easy installation in tight locations. Low cogging torque ensures consistent fold-line accuracy, while high dynamic response reliably handles hundreds of start-stop cycles per minute. With support for multiple mainstream communication protocols and compatibility with various control systems, plus a fully sealed enclosure that withstands paper-dust environments, this motor series helps folding equipment achieve long-term stable and efficient operation.
