USER'S GUIDE MOTION CONTROL SYSTEM, MSC-250
3 - 6 OPERATION AUGUST 1998
3.2 CONTROLLER USE AND STATUS
As discussed in Section 1, the MSC-250 servo controller is extremely flexible in its uses for
indexing system control. Depending on how the Macroprogram is written and how the
system is designed, it can be used in a variety of applications.
1. The controller can directly control one or two real axes with encoder feedback.
2. The controller has a pseudo-axis whose position can be broadcast on one or two
master angle buses. Either or both real axes can then use this pseudo axis as a
reference.
3. The feedback signal from either real axis can be broadcast over either or both
master angle buses, or the feedback signal from one real axis can be broadcast
over one master angle bus and the feedback signal from the second real axis
can be broadcast over the second master angle bus. As required by the
Macroprogram, each axis can periodically reference the other.
4. A position signal from another controller can be received at the fiber optics
receiver and transmitted over one or both master angle buses. Either or both
real axes can then reference this signal.
NOTE
While an axis is using a master angle bus for reference, the axis is
acting as a "slave" and the axis or controller supplying the reference
signal is acting as the "master".
During controller operations, the status of the controller processors and axes are displayed
on the SYSTEM STATUS and AXIS STATUS displays. If there is an error or fault, the
code for this will also be displayed on the appropriate STATUS display (refer to Figure 3.2
and Figure 3.3).
NOTE
If the decimal point is illuminated in the SYSTEM STATUS display, it
indicates that the macroprogram is running. If the decimal point is
illuminated in the AXIS STATUS display, it indicates that the axis is
enabled.
