Q1% shows the position of the auxiliary (or reference) encoder, relative to
the position at power up. The DPL program can change the value in this
parameter at any time.

Q2% is the target position for the slave, and is used as the input to the
profile generation block. When selected, the control loop will attempt to
make the feedback position (
speed profile is modified by the ramp rates (
