Standalone MMC Control
58 MMC Hardware Manual G & L Motion Control Inc.
This +24 Vdc appears as an output at several points on the MMC
connectors.
Figure 4-7 illustrates the pin-out.
The MMC co24 Vdc power from this connector to DC
power at voltages of +5 Vdc, + 15 Vdc, and -15 Vdc and supplies
them to the logic side of the system. The same supply that powers
the Control can be used for the field side of the system. Optionally,
an external power supply (or supplies) can be used for the field side
of the system. Such supplies are not routed through the MMC, but
they should all have the same power cut-off switch as the Control.
The 24 VDC applied at the MMC input power connector is also
available:
•
To power the DC outputs
•
To power the sink/source inputs
•
To power the axes interface
•
To power any attached MMC Option Modules
