Enter these values into the parameters.
Enter the threshold value (e.g. threshold = max. speed / 1000).
After introducing the values, the result obtained can be checked with the same stimulus.
Check the input set point on one channel and the P, PI, PI

output on the other channel. This
should give a result close to:
