Digital servo controller and data acquisition unit

  • 4-axis digital servo controller
  • 10kHz logging
  • Powerful and versatile software suite
  • Si-Plan 1085 digital servo-controller. A powerful and versatile solution for machine control and data acquisition

    The Si-Plan Electronics Research 1085 series digital servo controller and data acquisition unit is a development of the widely-used 879 controller. It offers a flexible, stand-alone system, for use with the company's range of test machines and as a retro-fit digital controller to existing machine frames from other manufacturers. Servo-control is implemented on the embedded processor. The control algorithm is user accessible via the PC interface.

  • 10kHz update interval for control
  • Data logging up to 10kHz
  • Up to 4 axes of servo-control
  • - Control using any input as feedback or generate a demand output for secondary controller
    - Proportional, Integral, Differential and Velocity with high or low pass filters
    - Adaptive control adjusts demand waveform to match demand peaks
  • Internal waveform generator for Sine, Triangle, Square, Parabolic or user waveforms. Alternatively, use an input as an external demand.
  • Multiple independent data loggers with multiple channels up to 10kHz from any input or any internal parameter.
  • Machine and test control by block or script programs
  • - 'C'-like compiled script language with full control over machine and test behaviour enables Si-Plan to produce bespoke application software when required.
    - Optional block programming module provides simpler control over the system to create complex test sequences.
