Main Features

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.

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.
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.
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 applicationHySTEP 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 designUsing 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.

Driver Specification


STEP-EC

STEP-EC-4X

Maximum motor rotation speed varies by resolution. When resolution is 10,000 ppr or less,
maximum rotation speed is 3,000 rpm. When resolution exceeds 10,000 ppr, maximum rotation speed is below 3,000 rpm.
