8.0A EtherCAT closed loop Stepper Drive for CNC Machinery

High-Current EtherCAT Drive for CNC and Robotics

The 8.0A EtherCAT closed loop Stepper Drive 3HCS2208H-17BC-EC is a digital-display fieldbus stepper drive oriented toward higher-power EtherCAT networks. Its 32-bit ARM core runs a power-angle closed loop algorithm that sustains motor torque through the middle and upper speed ranges. Supplied at 220 VAC, it provides up to 8.0 A of output current, making it a fit for machines that want fieldbus motion control and meaningful axis torque in the same package.

How closed loop Improves Torque

A Flatter Torque Curve

Unlike an open-loop drive that only sets a commanded phase current, this unit reads rotor position and actively adjusts the vector to keep the load synchronized. The result is a flatter torque curve as rpm climbs, and it is that margin that lets the drive cover tasks otherwise handed to servo electronics.

Current Headroom for Real Loads

The 8.0 A stage gives the machine usable reserve above the continuous demand, which helps on axes with short acceleration bursts and varying load.

EtherCAT Integration

The EtherCAT port accepts a standard motion bus, so multiple axes synchronize deterministically from one master controller. A built-in keypad and digital tube display let an operator set slave ID, baud rate, and rotation direction directly on the unit, which shortens commissioning on the factory floor.

Interface Summary

• Supply voltage 220 VAC with 0-8.0 A output current
• EtherCAT fieldbus for synchronized multi-axis control
• 5 digital inputs for homing reference and forward/reverse limits plus probe
• 3 digital outputs for brake, alarm, and in-position signals

Target Applications

Typical deployment includes factory automation, packaging machinery, compact CNC equipment, robotics, automated handling mechanisms, textile machinery, printing machinery, and food processing. The 220 VAC supply and 8.0 A stage suit machines that need current headroom alongside the speed of fieldbus networking.
