Detailed description of control bits
Bit
0
Manual run to larger values
Bit
1
Manual run to smaller values
Bit
2
Transfer target value
If this bit is set, the target value sent in the same process data telegram is
accepted as the new valid target value. A positioning run that starts
simultaneously or later uses this target value as the new target position. If a
positioning is to be started immediately together with the acceptance of the
target value, bit
4 (“release”) must be set simultaneously in addition to bit 2.
If bit 2 is not set, the target value is not accepted; instead, by setting the release
bit, a positioning run can be carried out to the target value last transferred and
marked as valid.
Bit
3
Reserved
must be set to 0
Bit
4
Release
Run commands will only be executed if this bit is set. This bit must be set for
positioning runs and manual runs. If this bit is reset during a run, the run will be
aborted and status bit
5 (“Run aborted”) will be set.
Bit
5
Reserved
must be set to 0
Bit
6
Run without loop
If this bit is set during positioning runs, all target positions will be approached
directly (independently of the current value in ISDU 124) without any loop.
Bit
7
Reserved
must be set to 0
Bit
8-9
