Servo amplifier that converts the output
Servo amplifiers are devices that enable ultra-precise motion control paired with servomotors. Amplifier is an abbreviation of “Amplifier”. In the case of audio equipment, it amplifies the signal, but in the case of servo amplifiers, it changes the energy of the supplied commercial power supply (100 V or 200 V) to the position/speed/torque command from the host controller, and converts the output so that the motor moves according to these commands. Yaskawa refers to servo amplifiers as Servo Pack.
