CONTROL TECHNIQUES LAUNCHES NEW SERVO FAMILY
Digitax ST dedicated servo range – intelligent, compact,
dynamic
A new range of servo-drives, with unprecedented connectivity,
feedback options, intelligence and functionality has been launched
by Control Techniques targeting the general Machinery Automation
market.
The Digitax ST range encompasses four models, each with
industry-leading features. Extremely compact in size and having
full compatibility with Control Techniques’ comprehensive range of
click-in function and communication modules, allowing the drive to
be customised easily and without special tools.
Lean manufacturing environments, demand smaller, more flexible
machinery, the Digitax ST range has been designed to meet these
requirements, offering machine manufacturers and system integrators
a compact servo drive with an unmatched range of flexible
integration features.
Digitax ST has been designed using a well-proven process that
prioritises innovation, reliability and customer involvement.
An example of this can be seen in Digitax ST’s compact, flat-sided
construction that allows high packing density for multiple axes,
other features such as the onboard motion and automation control
and a “Safe Torque Off” input reduce the need for external
components, further shrinking the machine size.
The drive is optimised for servo applications requiring high
peak torque, exceptional dynamic response, faster installation and
start-up as well as ease of integration. Four product
variants make up the range at launch – Base, Indexer, EZ Motion and
Plus.
The Digitax ST BASE model is designed to operate with a motion
controller (or PLC or PC), connected using either digital
communications such as SERCOS and EtherCAT or analogue
signals. The Base unit is quick and simple to configure using
the optional keypad, SmartCard or CTSoft, an intuitive drive
configuration tool that’s included with every drive. Typical
applications include packaging, pick-and-place or gluing machines
as well as material handling, X-Y tables and profiling machines
The Digitax ST INDEXER is designed for simple stand-alone
applications using its onboard motion controller offering accurate,
high speed point-to-point positioning. The Indexer is particularly
easy to set up using Sequential Function Chart (SFC), SFC is a
graphical programming language used by PLCs and is one of the five
languages defined by IEC 61131-3 standard.
The SFC programming environment is a part of the drive
commissioning software, CTSoft. The intuitive interface
enables users to quickly configure a range of motion commands such
as homing and various index moves, considerably saving development
and set-up time.
Option modules allow the drive to be integrated with other
automation equipment using fieldbus, Ethernet and expanded
I/O. Typical applications include indexing tables, fast
conveyor positioning, cut-to-length lines, punching or dispensing
machines and transfer units.
The Digitax ST EZ Motion unit utilises the popular PowerTools
Pro PC programming software that guides the user through the drive,
I/O and motion configuration for many indexing and synchronised
motor applications. High level software features help reduce
development time and motion configurations such as travel limits,
queuing and gearing are easily achieved within the PowerTools Pro
software using easy to complete forms and drag-and-drop
functionality. Users can quickly and easily achieve a precision
servo solution for indexing tables, pick-and-place, packaging and
high-speed labelling machines, dancer arm loop control and rotary
knife control.
Top of the range is the Digitax ST PLUS featuring a full
functionality motion controller optimised for high performance
machine cells requiring drive-to-drive networking, cam profiling
and synchronised motion (including virtual master). The
on-board drive-to-drive networking links multiple axes and enables
true distributed control. Configured using SyPT Pro, the
drive’s advanced motion features are configured in a flexible
IEC6113-3 style development environment using PLC-open motion
function blocks.>>>>>>>
