Setting ramp-up / down rounding time
Rounding times are recommended, since they prevent an abrupt response, thus avoiding
detrimental effects on the mechanics.
Rounding times are not recommended when analog inputs are used, since they would result
in overshoot / undershoot in the inverter response.
