INTRODUCING THE M–TRAVERSE
The M–Traverse is a highly accurate, digital, position controller. The M–Traverse's
technically advanced, internally embedded, control software is specifically designed for
the precise control of reciprocating lead/follower motion applications. These
applications are characterized by symmetric forward and reverse follower profiles. The
M–Traverse is often used for level winding, web scanning and fabric lapping, however it
can be used in any operation that requires symmetrical follower profiling against a lead.
The M-Traverse allows you to enter information that is unique to your system's
operation through user friendly Control Parameters. The M–Traverse uses this
information to calculate and determine a variety of controls and functions and frees you
from complex computations. When your system is engaged (Run), the traversing
mechanism (Follower) accelerates from the “Home” position to the preset laypitch
(Setpoint). Operating at the laypitch, the traverse mechanism can precisely align a
product on a reel or web then decelerate the traversing mechanism to the end of the
Traverse Length before beginning the end Dwell. At the “Dwell,” the M-Traverse
assures that the product is properly aligned before returning in the opposite direction.
The M–Traverse is remarkably precise - within one encoder line.
The M–Traverse accepts up to four preset pairs of “Setpoint” and “Traverse Length”
parameters. These parameters can be engaged with a quick flip of a switch during a
product change over. The M-Traverse features additional advanced control that
includes; profile definition that uses engineering unit parameters, dynamic profile
redefinition during a run, automatic profile generation, batch counting, unipolar/bipolar
drive compatibility and dynamic system monitoring. There are seven discrete outputs
for external control integration, which includes two user specified profile position
outputs.
Although the M–Traverse has many advanced control capabilities, it is easy to use. The
integrated keypad and display make access to the control and monitor parameters both
direct and simple. A “Keypad Lockout” function allows you to restrict access to the
control parameters after you have completed the setup process.
The M–Traverse features dedicated short-cut keys for quick access to the “Setpoint,”
“Batch Count,” “Tach,” and “Status” parameters. In addition to the integrated user
keypad and display, the M–Traverse has a RS-422 serial communications port through
which you can gain computer access to all of the control and monitor parameters.
Integrating the M–Traverse's applied intelligence with your system puts precise control
and perfect synchronization at your fingertips, quickly, easily and cost effectively.
