The count direction changes the sign during velocity measurement.
For the EtherCAT interface, no negative position values can be transferred. In this case, the
value 0 is output at the EtherCAT interface.
A suitable offset is to be selected so that only positive values are transferred.
Counting direction positive:
Counting direction negative:
Sub-index 05 offset value
The offset value in mm or inch/100, in accordance with the unit selected.
Output value = measurement value+offset.
If the preset value has been activated by a corresponding trigger signal, the preset value
has priority over the offset value.
Preset value and offset value are not offset against each other. The resolution of the offset
value is independent of the position value resolution selected. The offset value is active
immediately without any further release.
Sub-index 06 free resolution
Free resolution in mm/1000 or inch/100000, in accordance with the unit selected.
The "free resolution" parameters from sub-index 03 and the "value free resolution" from
sub-index 06 are mutually dependent. The value of the free resolution is multiplied by mm/
1000 or inch/100000 in accordance with the unit selected. The multiplication product is then
the free resolution that has been set.
