Evaluation and Programming Tool

Evaluation and Programming Tool

The evaluation and programming tool consists of an interface board and a software that allow you to:

  • Evaluate a POSIC encoder and compare it with a reference encoder
  • Program the resolution
  • Program an encoder identification number
  • Program a LookUp Table for linearization
