Main Setpoint

Main Setpoint is the speed reference defined in the PROFIdrive profile.
It is scaled such that -32768 to +32767 is -200% to +200% of the maximum speed
clamp (Pr 1.06). The converted value is then written to drive digital speed reference 1
(Pr 1.21).
The formula used for this conversion is:
Pr 1.21
