Notes:

  • The counter states are not reset when the counter underflows. In other words, the counter is only automatically set to zero if the reset value is reached from below.
  • The following ranges for the threshold values must be observed:
    Switch on threshold value < switch-off threshold value < reset threshold
  • Pulse length may be between 0.25 ms - 4000 ms
  • In pulse operation, the counter width must not exceed the counter runtime:
    max. pulse length < reset threshold/counter frequency
