Overview

AB2 Driver Amplifier

The AB2 amplifier combines the normal velocity mode of the AB1A amplifier, for servo operation, with the DC mode, for ultra-high resolution positioning. The DC mode treats the motor as a traditional piezo actuator, providing the ability to make discrete moves at the 1 nanometer level. The DC mode uses the same ±10V analog signal from the controller output and translates it to a ±300 nanometer position move capability, with 1 nanometer resolution. This function can be operated in an open loop or closed loop manner. The switching between the velocity mode and DC mode is done seamlessly through a discrete input signal.
