8.5 N·m Integrated Closed-Loop Stepper Motor with EtherCAT, CAN and RS485 (iHSS86-80-85-RC/EC)

Motor and Drive in a Single 86mm Package

The iHSS86-80-85-RC/EC mounts the fieldbus stepper drive directly onto the motor body, eliminating the separate driver enclosure that normally consumes panel space. For machines with several axes, this single-unit construction shortens cable runs between driver and motor, reduces wiring points, and simplifies machine assembly and service access.

Closed-Loop Control with 1000 P/R Feedback

A 1000 P/R incremental encoder closes the position loop. Instead of trusting open-loop step counts, the drive monitors actual rotor position and applies real-time error correction, which keeps the axis stable under load and reduces missed-step risk at start-stop transitions.

Fieldbus Connectivity: RS485, CAN and EtherCAT

Three communication options let the axis join an existing control network without protocol converters. EtherCAT suits high-speed synchronized multi-axis systems; RS485 and CAN fit simpler standalone or PLC-controlled lines.
