For automatic commissioning, p1037 and p1038 are set to the maximum motor speed (p0322) or to the
rated motor speed (p0311), provided that the maximum motor speed 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.
