Optimize the position approach

For all axes, MP1520 influences the slope of the run-in characteristic when close to the nominal
position

U [V]

t [ms]

MP1520 correct
MP1520 too large
MP1520 too small

Since MP1520 is effective for all axes, the worst axis determines the entry value. No axis should
show an overshoot of the nominal position.

If MP1520 is made too small, the approach times to the nominal position will be significantly longer.
So MP1520 must be carefully optimized!
