Digitax ST

High dynamic performance servo drives range

0.72Nm to 18.8Nm (Peak 56.4Nm)

200V / 400V

The Digitax ST range is optimized for pulse duty servo applications requiring high peak torque (up to 300% peak), dynamic response, ease of use and flexible integration features. The range is perfectly matched for use with Unimotor hd servo motors.

Four product variants ensure that the drive’s personality perfectly matches your servo applications.

Digitax ST – Plus

Features a full functionality motion controller, optimized for high performance machine cells requiring drive-to-drive networking and precision synchronization. The motion and communications are configured within a flexible IEC61131-3 software development environment using PLCopen function blocks. Fieldbus, Ethernet and I/O connectivity enable interfacing with other automation components and Intellectual Property protection ensures that your valuable knowledge remains secure.

Applications include: Printing, packaging, synchronizing conveyors, flying shear, rotary knife.

Digitax ST – EZ Motion

This drive offers a stand alone solution for many common indexing and synchronized motion applications. This is achieved using a unique PC programming interface that guides the user through the drive’s I/O and motion configuration.

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

Digitax ST – Indexer

Designed for simple stand alone positioning applications using an onboard position controller. Fieldbus, Ethernet and I/O enable connectivity to other automation components.

Applications include: Indexing tables, fast conveyor positioning, cut-to-length machines, punching.

Digitax ST – Base

Optimized for centralized control, to operate as an amplifier for motion controllers, motion PLCs and Industrial PC based motion systems using a wide range of digital or analogue interface technologies.

Applications include: Packaging, pick and place, glue depositing, x y cutting tables.
