Detailed description of control bits
Bit
0
Manual run to larger values
Bit
1
Manual run to smaller values
Bit
2
Transfer target value
When this bit is set, the target value in the process data is accepted as the new
valid target value. A positioning run starting at the same time or later will use this
target value as the new target position. If the positioning run is required to start
as soon as the the target value has been transferred, bit
4 (“release”) must also
be set.
If bit 2 is not set, the target value will not be accepted. Instead, a positioning run
can be started to the last transmitted target value that has been 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 deleted during a run, the run will
be aborted and status bit
5 (“Positioning run aborted”) will be set.
Bit
5
Reserved
must be set to 0
Bit
6
Run without a reference loop
If this bit is set, all target positions will be approached directly during positioning
runs (independently of the current value of SDO #201F), without a reference
loop.
Bit
7-12

must be set to 0
Bit
13:
Toggle bit
The drive always writes this bit in status word bit 2.
The control unit can recognise when new process data from the drive are
processed.
Bit
