The XPS-DRV01 is a software configurable PWM amplifier that is compatible with most of Newport’s and other companies’ DC brush and 2-phase stepper motor positioners. When used with Newport stages, the configuration of the amplifier is easily completed using the auto-configuration utility software, or advanced users can manually develop their own configuration files specifically optimized for each application. The XPS-DRV01 motor driver supplies a maximum current of 3 Amps and 43 Volts. It can drive unipolar and bipolar 2-phase stepper motors in microstep mode (sine/cosine commutation) and DC brush motors in velocity mode, for motors with a tachometer, or in voltage mode, for motors without a 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 can be used. Please note that the XPS-DRV01 driver card does not fit in slot 1 on the XPS-RLD, use the other slots for this driver board.
When an ESP-compatible stage is connected to the XPS, the stage is quickly recognized and operating parameters are configured without the need for user inputs. This Plug and Play feature is not only transparent to the user, but it also ensures the safe operation of the stage.
