4.5 N·m Integrated Closed-Loop Stepper Motor for Fieldbus Automation (iHSS86-60-45-RC/EC)

Integrated Construction Reduces Axis Footprint

By housing the driver electronics in the motor enclosure, the iHSS86-60-45-RC/EC removes a separate drive module from the control cabinet. This 86 mm frame integrated unit is suited to machines where panel space is limited and axis modules are mounted close to the process.

Application scenarios

Fieldbus communication makes this motor part of a networked, coordinated machine. On CNC machine tools it powers auxiliary axes that talk to the PLC over EtherCAT for clock-synchronized motion. Packaging lines use it on folder, sealer and indexing stations where the RS485 or CAN bus shares setpoints across many axes. Factory automation builds coordinate any axis into an overall motion plan, and precision robotic mechanisms use the closed loop for repeatable joint positioning. Textile and printing machinery run guider rolls and tensioning axes, while food processing and automated handling mechanisms use the networked control for synchronized conveyors and diverters. The 60 VDC supply and 1000 P/R feedback keep wiring and homing simple on these lines.

Encoder Feedback for Position Security

The built-in 1000 P/R incremental encoder feeds rotor position back to the drive every control cycle. Closed-loop correction compensates for load variation and helps prevent step loss, making the axis more predictable during frequent starts, stops and reversals.

Three Protocol Options on One Motor

RS485, CAN and EtherCAT interfaces are selectable, so the same mechanical mounting can serve different machine lines. This flexibility simplifies stocking and lets a single design cover both simple PLC networks and real-time EtherCAT systems.

Engineering and Selection Notes

Choose the communication protocol at design time based on your controller. For multi-axis coordinated motion, EtherCAT gives the tightest timing; for simpler lines RS485 or CAN reduces cost. The 6.0 A rated current and 60 VDC rail need a regulated supply and adequate cable gauge. Because feedback is incremental, establish a reference move at startup on machines that require an absolute origin. The compact 86 mm integration removes a driver panel from the cabinet, simplifying maintenance access.
