Introduction
The Digitax ST family of servo drives are available with five levels of intelligence:
•
Digitax ST Base
•
Digitax ST Indexer
•
Digitax ST Plus
•
Digitax ST EZMotion
•
Digitax ST EtherCAT
The Digitax ST Base drive operates in velocity or torque modes and is designed to
operate with a centralised motion controller or as a standalone drive.
The Digitax ST Indexer drive performs point-to-point motion profiling including relative,
absolute, rotary plus, rotary minus, registration and homing motion. The Digitax ST
Indexer will operate as a single standalone system controller. Alternatively, the Digitax
ST Indexer can form part of a distributed system where commands are sent over a
fieldbus or through digital input/output signals.
The Digitax ST Plus drive offers all the features available on the Digitax ST Indexer
drive with the addition of performing complex motion as a single axis or synchronised to
a reference axis. This offers digital lock and electronic camming via a virtual master
reference.
The Digitax ST EZMotion drive is part of the Motion Made Easy family of servo drives
and allows the user to create programs to sequence motion, I/O control, and other
machine operations in one environment. Digitax ST EZMotion also supports advanced
functions such as a Position Capture Object, Multiple Profile Summation, Queuing, and
Program Multitasking.
The Digitax ST EtherCAT drive offers onboard EtherCAT allowing the product to be
connected to an EtherCAT network as a slave device. It can be used in a variety of
applications, including those requiring accurate synchronization and precise motion
control.
All variants provide a Safe Torque Off function. This function is identical to that referred
to as "SECURE DISABLE" in the Control Techniques Unidrive SP product range. The
name has been changed in accordance with draft standard pr EN 61800-5-2 (future IEC
61800-5-2, EN 61800-5-2).
Four documentation guides are available for Digitax ST, these cover all variants:
