AB1a Driver Module

AB1a Product Description

The AB1A amplifier is a single axis digital driver that can run one or multiple Nanomotion motors in parallel.

While operating in a closed loop servo system,the driver works as a velocity amplifier, receiving a +/- 10 volt analog command from the controller. The controller signal translates into AC voltage at 39.6 kHz to run the motor.

In an open loop mode the amplifier can receive a signal from an external joystick, providing motion in a continuous or stepping mode.

AB1a Features

• Digital Drive Handles Up to 32 Elements
• Available in Eurocard 3U Format
• +/- 10V Input from Servo Control
• Joystick Input for Open Loop Operation
• 2 Optically Isolated Limits
• Card Interface is 48 Pin 3 Row Connector
