NDMS1

 

 

The NDMS1 (NOVA Device Multiphase Servo Number of Ports 1) is a device only for the DSP50 piezo positioner.

 

 

  • Very stable and linear voltage curves
  • Voltage for the piezos can be changed in very fine gradations
  • Device is for a piezoelectric initial drive with four independent phases (DSP50)
  • Computational step size is smaller than 1nm
  • Positioning measurement system has a resolution of 1nm
  • Device has a position control with change both the step size and the step frequency
  • Temperature measurement (PT1000) inside the DSP50
  • Step size and step frequency (velocity) is adjustable in a wide range
  • Device has a hard limit detection with automatic shut off - thresholds are adjustable
  • Go to limit and search reference functions
  • Slow voltage change at startup
  • Maximum speed is 1mm/s with depends on the connected positioner
  • Absolute and relative step counter
  • Yellow LED shows the power state & green LED shows the bus traffic
  • Case has an additional ground connector
  • Time constants for the servo loop are adjustable
  • Device has a programmable device ID to use more devices of the same type
