Motor Feedback Description: For rotary feedback the resolution parameter of feedback 1 (motor feedback) defines the number of
cycles per revolution of the motor. For a sinusoidal device this represents the number of periods per revolution.
For a TTL devices this represents the number of lines per motor revolution. For a linear feedback the grid constant
is entered. For the standard Stegmann motor feedback devices this will be self identified at 1024 counts.
