Step Drive

Features

Ezi-STEP is a micro stepping system. In other words, a motor and a drive are integrated seamlessly together. Because it is an unit product, Ezi-STEP makes it possible to apply many functions compared with a conventional stepping motor, such as the senseless detection of the loss of syncronization, smooth control over the whole velocity range by software damping control, and no vibration at the low speed range.

For high-speed and high-precision drive of a stepping motor, Ezi-STEP is an unique drive that adopts a new control scheme owing to an on-board high-performance digital signal processor. With an unique position estimation algorithm it instantaneously detects an out-of s ynchronization
based on the rotor position of the stepping motor, which is not an easy task in a conventional stepping motor and drive(effective only over 300 rpm).
Utilizing a software damping and filtering method, a high speed actuation is realized by the exciting angle control of a step-angle.
The resolution of Ezi-STEP can be improved from basic 1.8°up to 0.0072°(1/250).
In addition it generates various signals including sensorless stall detection alarm and
running signal.

• Senseless Stall Detection
• Software Damping
• Run/Stop Signal Output
