Starting a positioning run
To control the drive, it must first be switched to the IO-Link state "operate".
The following sequence of steps is possible:
- Transfer target value:
Command byte = 0x14 and desired target value
Drive begins run
- Aborting a run by withdrawing release:
Command byte = 0x00
Note:
If a new target value needs to be set during an active positioning run, the
drive must be stopped (reset the release bit). The new target value can be set
when the drive is at a standstill.
Note:
If a manual run is required during an active positioning run, the drive must
be stopped (reset the release bit). The manual run can be started when the drive is
at a standstill.
The following sequence of steps is also possible:
Starting conditions: release has not been set.
- Transfer target value:
Command byte = 0x04 and desired target value
- Set release:
Command byte = 0x10
Drive begins run
- Aborting a run by withdrawing release:
Command byte = 0x00
Positioning runs may include a “loop run”, which causes the target to be approached from a
defined direction. The direction and length of the loop run can be set to the desired value
with ISDU 124 (“loop length”) before the positioning run begins. ISDU 124 can also be used
to deactivate the loop run.
