AB2 Amplifier from NanomotionAB2 Amplifier from Nanomotion

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.


  • Ultra High Resolution Capability using DC Mode
  • Digital Drive Handles 16 HR Motor Elements (2 x HR8 motors)
  • Four Operation Modes: Velocity, Step Gate and DC
  • Discrete Inputs Enabling Feedback from External Sources, such as Limit Switches, Emergency Stop Command
  • Requires 24Vdc Supply Input
  • Cable Length up to 20m - Minimized Sensitivity to Cable Lengthening
  • Over Current and Over Voltage Protection
