1.15.7.1 Dancer Constant Measurement
With the dancer placed in a lower limit switch position, perform the self-tuning of the analog input connected to PID fbk src.
Set the Drive keypad on the PID fbk mon parameter.
Measure and multiply by 2 the distance in
mm between the lower mechanical limit switch and the dancer
position, where the PID fbk mon parameter has a 0 value (electric 0 position).
Multiply the calculated value by 2 if the dancer is made of a single pitch, by 4 if it is made of two pitches etc. etc.
as per the above figure.
