AC Drive (VFD) Heavy Duty

AC servo drive is an electronic amplifier used to power electric servomechanisms. AC servo drive monitors the feedback signal from the servomechanism and continually adjusts for deviation from expected behavior.

AC servo drive receives a command signal from a control system, amplifies the signal, and transmits electric current to a servo motor in order to produce motion proportional to the command signal.

Typically, the command signal represents a desired velocity, but can also represent a desired torque or position. A sensor attached to the servo motor reports the motor's actual status back to the servo drive.

The AC servo drive then compares the actual motor status with the commanded motor status. It then alters the voltage, frequency or pulse width to the motor so as to correct for any deviation from the commanded status.
