A response to command m, for example, might look like: „m,b63a". The value b63a
46650 , this corresponds to a position of 83,89%, based on the closed-loop-range.

Example 1:
A jump (in open loop mode), with a record duration of t=200ms and a sample rate of ∆t=100µs
shall be recorded. From this follows a sample count of 2000 (you can always sample more, but
minimum the desired readout length). Afterwards the position values are read out, followed by the
voltage values. Thus, the minimum sample count is 2000 based on the calculation
