During the machine
build phase, Quin supplied a 16-axis SERVOnet
Control System, including
servo
drives, motors and gearboxes. The equipment was
installed in electrical cabinets by Quin and
tested as
a system before being shipped off to the machine
builder. The completed system was tested against
a
Quin-prepared Test Specification before its final
installation and commissioning at the customer’s
site.
The application incorporates the following
motion control principles:
- tension control (including web break and
reel run-out detection)
- linear and non-linear position synchronisation
including phase adjustment
- linear speed synchronisation
- high speed indexing using absolute and relative
moves
- torque-limited absolute moves
- registration control
- digital control of pneumatics using software
generated “cam switches”
- Data Highway communications to a PLC
- A modem in the electrical cabinet allows
for remote diagnostics. It is possible
to monitor
graphically
and simultaneously up to 4 parameters
from any of the 16 axes, and data
leading up
to an event
can
be automatically logged for subsequent
analysis.
