7.4.2 - Adjustment of the internal speed (VIT INT) and the maximum speed (VIT MAX) via
potentiometers.
The "VIT MAX" potentiometer is used to reduce the maximum speed for a maximum
reference, independently of the setting of S4. The "VIT INT" potentiometer is used to adjust an
operating speed : it replaces the adjustment of the external potentiometer. Access to these
settings depends on the position of the selector switches (S1, S2, S3).
