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

Si-Plan 1085 digital servo-controller. A powerful and versatile solution for machine control and data acquisition

Description
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.

Firmware

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.
