The ramp set for voltage reduction serves as slope limitation in order to prevent that
voltage is suddenly applied to the motor when the Eco function is deactivated.
Otherwise, the overvoltage limitation (Imax, Clamp) would be activated.
This ramp is, depending on the device, pre-initialised to approx. the triple rotor time constant.
An adaptation of this parameter is not required.
