National Instruments / nuLogic nuDrive Power Amplifiers
Features

• 2 or 4 Axis
• Uses PWM Amplifiers
• Stepper and DC Brush Servo Drivers
• 115V AC Input

The National Instruments / nuLogic nuDrive Power Amplifier is a complete power amplifier and system interface for use with up to four axes of simultaneous or independent servo or stepper motion control. Ideally suited to industrial and laboratory applications, the nuDrive has everything needed to connect motors, encoders, limit switches, I/O, and other motion hardware to National Instruments motion controllers.

The nuDrive can drive a broad range of servo or stepper motors. Servo nuDrives use pulse-width modulation (PWM) amplifiers with a user-specified peak output current rating and a DC bus voltage to drive servo motors. Stepper nuDrives use a rugged microstepping bipolar chopper driver. Stepper driver configurations are available in a wide range of user-specified current per phase and voltage settings to drive stepper motors. In all configurations, power supplies are built in and use standard 115 VAC for operation. Electronics are fan cooled to assure reliable operation.

nuDrives simplify field wiring through separate encoder, limit switch, and motor power removable screw terminal connector blocks for each axis. The terminal blocks do not require any special wiring tools for installation.
