Digitax ST-Z (EZMotion)

1.7 A – 8.0 A rms (5.1 A – 24 V Peak)

200-240 V | 380-480 V

The Digitax ST-Z drive offers a standalone solution for many common indexing and synchronized motion applications.

Out-of-the-box motion control in less than five minutes is achieved using a unique PC programming interface that guides the user through the drive’s I/O and motion configuration.

Features

Utilizing a familiar Windows® interface, machine builders can quickly set up and program the Digitax ST-Z to perform almost any motion profile.

Applications requiring camming, indexing, electronic gearing, velocity and torque modes can be accomplished through simple drag-and-drop, fill-in-the-blank set-up.

Real-time programs with “Basic-like” command structured text can be used to program the machine sequencing. The programming interface guides the user through the drive, I/O and motion configurations.

Applications include: Indexing table, pick-and-place, packaging machines, dancer arm loop control.
