9.6.2 Modification of Parameterized Initial and End Values
Meaning of the B bit: At the first parameterization of an initial or an end setpoint the B bit is irrele-
vant.
If a track needs to be modified, there are the following possibilities:
—
The set B bit erases the initial or end value in the selected track. A possible assigned setpoint is
irrelevant.
This method is for modifying single tracks. The software-based erasing in section 9.6.4 is rec-
ommended for erasing all tracks.
– B bit= “O” replaces the old setpoint with a new setpoint (in the selected track).
