If the efficiency of servo amplifier is considered, it is practicable that the power supply voltage is about 3 times as large as the servo amplifier output voltage corresponding to rated current.
If we simply back-off the input signal to achieve the linearity required for the poweramplifier, the power amplifier efficiency will be very low for high PAR signals.
