QManager delivers distributed motion control for modular machines
Distributed motion control systems gain a significant improvement
in performance and flexibility, with the introduction of QManager
from Quin Systems. QManager provides the hub of a modular machine,
capable of growing from a simple system with several motion axes,
up to a complete production line.
Using SERVOnet® to
link with intelligent drives and motion controllers, QManager
organises and communicates,
configuring
all drives and controls on the network from a single central
program, then monitoring and interacting with them while the
machine is running.
“Like any good leader, QManager gets the best out of its
team through delegation”, said managing director Mike Webb. “Conventional
systems either try to impose central control, imposing a huge
'bureaucratic' overhead on the controller, or allow all the drives
to do their own thing, reducing the element of control and lowering
efficiency. But by distributing the processing throughout the
network – leveraging the processing power of individual
drives and other devices – machine builders can achieve
exceptional modularity and scalability.”
Unlike centralised control systems, QManager can manage and
synchronise systems ranging from simple single drives, right
up to the 60-node limit of SERVOnet, so is capable of running
machines with as many as 240 axes. It encompasses nearly all
types of motor, including AC asynchronous, DC brushed and stepper
types as well as brushless AC servos. Distributed digital and
analogue I/O, in addition to motor control, is also provided
by connecting QDrives to SERVOnet.
Compared with existing Quin machine controllers, the new device
can run more tasks, faster, and has the widest range of interface
options in the industry. In addition, motion controllers and
drives connected to SERVOnet can run local motion and I/O tasks,
greatly improving external event reaction time.
It sports 100Mbit/s Fast Ethernet for linking any device on
the network to PC networks, connects to PLCs through Profibus
and DeviceNet, and in time will offer an infrared link for simpler
local programming, monitoring and diagnostics. Also new are up
to 32 input and 16 outputs for direct digital I/O connections,
and additional I/O including analogue and encoder inputs may
be managed via the two CANbus (CANopen) ports. In many cases
this will eliminate the need for a PLC, further cutting the cost
of hardware, wiring and programming.
Modular machines are
programmed with the in-built PTS (Programmable Transmission
System) software – a
mnemonic language that is easy to learn and based on mechanical
concepts particularly
suitable for machine designers. It delegates tasks to intelligent
drives by using event-driven code rather than the loop routines
common with PLCs. Nevertheless, it is fully interactive, allowing
changes to be made while machines are running.
The software suite includes powerful Windows-based tools for
diagnostics, motion generation, configuration and tuning. For
example, motion profiles can be designed and visualised in terms
of position, velocity, acceleration and rate-of-change of acceleration
(jerk). Its large library of standard machine functions includes
registration, tension, gearing, cams and even more complex algorithms.
Powerful machine diagnostics are available through the PTS Scope
software, which allows users to check timings and performance
in real time. What is more, the scope can be operated via an
Internet connection or modem, enabling machines to be supported
anywhere in the world.
QManager is packaged in a slim (75 mm wide)
275 mm high x 195 mm deep module. More information about the
QManager can be found in our products area.
