There are 4 configuration parameters for the MDrive. Please note that the
motor Direction Override (DIR) is only available on MDrive Microstepping
"C" Connector versions. Parameter settings are automatically saved to
memory when the "SET" button is clicked on the IMS Motor Interface
screen. These parameters may all be changed on-the-fly.
The Table below summarizes the parameters and their function, range, units
and default setting.

M o t o r H o l d i n g C u r r e n t ( M H C )
The MHC parameter sets the motor holding current as a percentage of the full
output current of the driver. If the hold current is set to 0, the output circuitry
of the driver section will disable when the hold current setting becomes active.
The hold current setting becomes active 200ms following the last clock pulse.
M o t o r R u n C u r r e n t ( M R C )
The Motor Run Current (MRC) parameter sets the motor run current to a
percentage of the full output current of the MDrive driver section.
