Smart Component

Step Motor / EtherCAT Driver

Closed-Loop Stepping System with 20,000 Pulse Encoder

Equipped with a high-resolution 20,000 pulse encoder, the system delivers superior precision compared to conventional stepping motors.

Main Features

Precision Motor and EtherCAT Driver Line-Up

HySTEP provides closed-loop stepping control, high torque, fast response, 

high resolution, detachable cables and multi-axis EtherCAT driver options.

1

Closed-Loop Stepping System

Anti-slip and position correction
Equipped with a 20,000 PPR encoder for precise speed and position control during motion, 

with feedback ensuring accurate tracking, slip prevention, and position correction.

2

No Gain Tuning, No Hunting

No Gain Tuning
Leverages stepper motor characteristics for fast, tuning-free operation, ensuring easy use.

No Hunting
Lower vibration and noise than conventional stepper motors, with no residual vibration at standstill.

3

Improved Torque

HySTEP provides high torque even at high RPM, reducing acceleration time and 

allowing continuous operation with higher torque compared to typical servo motors in low speed ranges.

4

Fast Response Time

HySTEP leverages high inertia for fast positioning, supporting high-speed 

intermittent operation, bidirectional switching, and microstepping.

5

High Resolution

Depending on the application, it can be finely segmented into various 

position resolution units (500 to 20,000 pulses per revolution).

6

Detachable Cables

Detachable cables with flexible direction options support various configurations, 

while simple installation and maintenance ensure easy servicing.

7

Multi-Channel Application

Up to 4 axes application
HySTEP 4X is an EtherCAT slave module enabling independent 

control of up to 4 axes, supporting multiple motor types per axis.

8

Applying Hollow Shaft Motors

Miniaturization and lightweight design
Using hollow shaft motors compatible with HySTEP DRIVER can lead to cost savings. 

Hollow shaft motors have an empty shaft that allows cables and pipes to be inserted for use.
