Drive Options
The XPS controller is capable of driving up to 8 axes of most Newport positioners using
driver cards that slide through the back of the chassis. These factory-tested drives are
powered by an internal 500 W power supply, which is independent of the controller
power supply. When used with Newport ESP stages, the configuration of the driver
cards is easy using the auto-configuration utility software. Advanced users can also
manually develop their own configuration files optimized for specific applications.
The XPS-DRV01 is a software configurable PWM amplifier that is compatible with
most of Newport's and other companies' DC brush and stepper motor positioners.
The XPS-DRV01 motor driver supplies a maximum current of 3 Amps and 48 Volts. It
has the capability to drive bipolar stepper motors in microstep mode (sine/cosine
commutation) and DC brush motors in velocity mode, for motors with tachometer, or
voltage mode, for motors without tachometer. Programmable gains and a programmable
PWM switching frequency up to 300 kHz allow a very fine adjustment of the driver to
the motor. For added safety, a programmable over-current protection setting is also
available.
