MDSC Functionality
The Master Driven Speed Control (MDSC) function provides the ability to
synchronize one or more motion axes to a common Master Axis. The MDSC uses
the Motion Master Driven Axis Control (MDAC) instruction, which assigns a
Master:Slave relationship for single axes.
The MDSC function provides synchronization of axes without the use of CAM
profiles. The MDSC functions can also be used with Time Driven CAM profiles
(MATC) to make them act like position driven profiles synchronized with a
Master Axis.
This information applies to the CompactLogix 5370, ControlLogix 5570,
Compact GuardLogix 5370, GuardLogix 5570, Compact GuardLogix 5380,
CompactLogix 5380, CompactLogix 5480, ControlLogix 5580, and GuardLogix
5580 controllers. Controller differences are noted where applicable.
