Setting Up the UDC and PMI Meter Ports

If your system configuration incorporates an AutoMax Distributed

Power drive, the Monitor Set Up UDC/PMI menu allows you to

select variables to drive the four D/A output ports (labeled Meter

Ports") on each of the UDC modules and PMI Processors. The

analog signals output by these ports can be used to drive meters,

chart recorders, or other test instruments. Refer to the appropriate

DPS Configuration and Programming instruction manual for more

information on connecting equipment to the UDC and PMI meter

ports.
After the slot number of a UDC module is entered, the user can enter

or modify setup information about the meter ports for the UDC

module or for either of the PMI Processors associated with that UDC

module. See figure 18.9 for the UDC Setup screen display.
Note that both the configuration file and the drive parameter file

(.POB file) must be downloaded to the UDC before you can set

up the UDC or PMI meter ports using Monitor.
