After the reference was cleared, the new actual position value
(S-0-0051/S-0-0053), with inactive drive ("AB" or "bb") and with drive in
"Drive Halt (AH)", is set according to the preselected reference position
(see Fig. "Actual position values after "set absolute measuring""). The
new position reference takes immediate effect.
After the reference was cleared, there are the following possibilities, with
active drive, regarding the switching of the actual position value to the
new position reference:
•
Deactivating drive enable:
When the drive goes to the inactive state, the new actual position
value (S-0-0051/S-0-0053) is set according to the preselected
reference position (see Fig. "Actual position values after "set absolute
measuring"").
•
Starting the "drive-controlled homing procedure" command:
The drive becomes independent of the preset command values and
internally presets the current actual velocity value as the command
value. The new position command value (S-0-0051/S-0-0053) is set
according to the preselected reference position (see Fig. "Actual
position values after "set absolute measuring"") and the "drive-
controlled homing procedure" command is reported by the drive to
have been executed. The master now has to "synchronize" to the new
actual position value of the encoder used in the active operating mode.
After the master cleared the "drive-controlled homing procedure"
command, the drive goes to master-controlled operation again.
Note:
"Set absolute measuring" with a moving axis is possible, but
makes sense only with master-side presetting of the reference
position!
When the new position reference of the selected encoder has been
established, the reference of the respective encoder is displayed in
S-0-0403, Position feedback value status
and the absolute encoder
offset is stored (depending on storage mode; see above). Finally, the "set
absolute measuring" command has to be cleared by the master!
