Digital part - Counter - Operating modes
For the counter, the following operating modes are available separate
configurable:
• Count endless – Distance measuring with incremental encoder
• Count once – Count to a maximum limit
• Count periodic– Count with repeated counter process
In this operating mode, the counter counts from 0 res. from the load value.
When the counter counts forward and reaches the upper count limit and
another counting pulse in positive direction arrives, it jumps to the lower
count limit and counts from there on.
When the counter counts backwards and reaches the lower count limit and
another counting pulse in negative direction arrives, it jumps to the upper
count limit and counts from there on.
The count limits are set to the maximum count range.
