Description
1.1 General
The AB5 is a 24V single axis amplifier box for driving Nanomotion Piezo-Ceramic
motors, which eliminates the “dead zone” previously associated with Piezo-Ceramic
operation. It interfaces between the input command from a controller or joystick to
the motor. As a result, it provides the smooth control of a DC motor and the
accuracy and stability of a Piezo motor.
The AB5 box consists of three cards that convert the input command signal into the
output voltage necessary for Nanomotion motors. The Logic and Driver cards are
common to all AB5 configurations, while the Personality card is configuration
specific and can be replaced when a motor type or number is changed.
