More Compact Machinery

Digitax ST is an extremely compact servo drive that can be
mounted side-by-side with other drives or components without
leaving space. The result is an incredibly high packing density for
multiple axes. Onboard features such as synchronised motion
control and Safe Torque Off reduce the need for external
components further reducing cubicle sizes and cost.

Matched Motors

Unimotor FM is a performance matched range of servo motors.
FM means Flexible Motor, available in six different diameters with a
wide range of motor lengths, rated speeds and feedback devices.

Factory fitted options include integral
brakes and servo gear boxes.
Digitax ST operates successfully with
other manufacturers’ servo motors
including linear motors and almost
any feedback device.

Increased Value

How do you increase the value of your machines while
reducing your costs? Digitax ST offers reliability, and the
performance to increase speed, repeatability and accuracy while
also reducing the size and cost. Digitax ST addresses all of the
challenges associated with modern machine design.

Analogue/Motion Fieldbus

Typical Architecture Key Benefits

Option modules with synchronous drive connectivity allow the
drive to interface using dedicated servo networks such as
EtherCAT, SERCOS and CANopen. Compliance certification
ensures interoperability with other manufacturers’ equipment.

The standard I/O includes high speed Freeze input for position
capture, high resolution analogue input and an encoder output
to enable the drive to be connected to traditional motion
controllers.

The on-board universal encoder input is able to connect to
Incremental, SinCos, Hiperface, EnDAT and SSI encoders
allowing you to choose the best feedback device for each
application.

As standard the drive features a Safe Torque Off input, which
disables the output stage of the drive with a high degree of
security. This reduces the cost of complying with machine safety
standards such as EN954-1 Cat 3 and enables the drive to
integrate easily with the machine safety system.

DIGITAX ST – INDEXER

Typical Applications

● Indexing tables

● Fast conveyor positioning

● Cut-to-length machines

● Punching

● Transfer mechanisms

● Fast and precise fluid dispensing

Easy to use, point-to-point positioning

Digitax ST - Indexer has the same high performance features as
the Base model, but additionally offers easy to use point-to­point positioning functionality. The drive can operate as a
standalone controller or integrate with a wider automation
system using fieldbus and I/O. The drive and positioning
features are commissioned using CTSoft, an intuitive drive
configuration software that is included free with every drive.
