MM30000 series
Minarik’s MM30000A series drives can be operated with their
boards sharing one common. This series of drives is the only
Minarik series that permits more that one drive to follow a single
PCM4 module. See Figure 9.
The number of MM30000-type drives that can be driven by one
PCM4 is limited by the output impedance of the PCM4.
Potentiometers may be wired in parallel with the PCM4 output
for final speed adjustments and ratioing. The net resistance of
these paralleled ratioing pots must be at least 800 ohms.
Multiple follower requirements
Warning
Most Minarik variable speed drives cannot be wired with
their speed-setting circuits in common with each other. They
require a dedicated PCM4 for each variable speed drive.
Included are all Minarik models in the MM20000 series, XL
series, and all regenerative drives (RG series). A multiple
follower system using any of these drives must consist of a
master PCM4 driving follower PCM4 modules. See pages
18 and 19 of this manual.
