42.6.2.6.3 Speed Measurement

The following speed measurement can be done using velocity event output (VLC) and Timer/Counter (TC/TCC) device resources:

  • Continuous velocity measurement: TCz measures the time on which n VLC (TCy) output events occur.
  • Synchronous Velocity measurement: At a specific motor position TCCz, the time is measured during which n VLC (TCCy) output events occur.
  • Slow Velocity measurement: Measure the number of VLC output events (TCCy) and the delay since the last VLC output event (TCCz) within a given time slot (TCk).
