f_max (reference value for
ramp-function generator p1082)
For automatic commissioning, p1037 and p1038 are set to the
maximum motor frequency or to the rated motor frequency,
provided that f_max_mot has not been specified.
If initial rounding-off is active (p1030.2 = 1), the selected ramp-up/
down times are exceeded accordingly.
Only effective if p1030.0 = 0.
