2-5 Analog Settings (CQM1-CPU42-EV1/CPM1/CPM1A Only)
In the CQM1-CPU42-EV1/CPM1/CPM1A PCs, the analog settings function
automatically transfers the settings on the CPU Unit’s adjustment switches to
IR 220 through IR 223. This function is very useful when there are set values
that need to be precisely adjusted during operation. These set values can be
changed just by turning the adjustment switches on the CPU Unit.
The adjustment settings are stored in BCD and range from 0000 to 0200. Use
a precision screwdriver to adjust the settings. (Turn the switches clockwise to
increase the adjustment.)
CQM1-CPU42-EV1
Settings
The CQM1-CPU42-EV1 has four analog adjustment controls. The following
diagram shows the CQM1-CPU42-EV1 adjustment controls and indicates the
corresponding IR words that contain the adjustment settings.
In CQM1 CPU Units other than the CQM1-CPU42-EV1, IR 220 through IR
223 serve no special purpose. They can be used as work words in the pro-
gram.
!Caution The CQM1-CPU42-EV1 continually refreshes IR 220 through IR 223 with the
adjustment settings as long as the power is on. Do not overwrite the content
of these words from the program or Peripheral Device.
CPM1/CPM1A Settings The CPM1/CPM1A PCs have two analog adjustment controls. The following
diagram shows the adjustment controls and indicates the corresponding SR
words that contain the adjustment settings. Use a phillips-head screwdriver to
adjust the settings.
Note The above diagram shows the CPM1, but the settings are the same for
CPM1A.
The analog setting for control 0 is in IR 220.
The analog setting for control 1 is in IR 221.
The analog setting for control 2 is in IR 222.
The analog setting for control 3 is in IR 223.
The analog setting for control 0 is in SR 250.
The analog setting for control 1 is in SR 251.
