Sub-index 04 Counting direction
Attention!
Encoder specification DS406 specifies that the counting direction can be set in object 6000
bit 3. Object 2000 sub-index 04 and object 6000 bit 3 overwrite each other.
The counting direction changes the sign during velocity measurement.
No negative position values can be transmitted on the EtherCAT interface. In this case, the
value 0 is output on the EtherCAT interface.
An appropriate offset must be selected such that only positive values are transmitted.
Counting direction positive:
Counting direction negative:
Sub-index 05 Offset value
Offset value in mm or inch/100 depending on selected unit.
Output value = measurement value + offset.
If the preset value is activated by a corresponding trigger signal, the preset value has priority
over the offset value.
The preset value and offset value are not offset against each other. The resolution of the
offset value is independent of the resolution selected for the position value. The offset value
is immediately active without any further release.
Sub-index 06 Free resolution
Free resolution in mm/1000 or inch/100000 depending on the selected unit.
The "free resolution" parameters from sub-index 03 and the "free resolution" value from sub-
index 06 are mutually dependent. The value of the free resolution is multiplied in mm/1000
or inch/100000 depending on the selected unit. The product of multiplication is then the set
free resolution.
