nuDrive Accessory User Guide
Table 1 lists the available nuDrives and describes the properties of each
nuDrive.
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 your 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.
Refer to Table 2 for a summary of how to connect various motion
controllers to different nuDrives.
