7. Determine the commutation angle offset
Incremental
With an incremental measuring system:
measuring system
Yes, Hall sensor
boxes present
The coarse synchroniza-
tion is obtained from the
Hall sensor signals (C/D
track) on switching on
Several zero markers with cams
or distance-coded reference
markers from VSA 06.07.07
Set MD 1017 ("Start-up help") to 1
Reference axis on the NCK side
When it moves over the zero mar-
ker, the commutation angle offset
is entered in MD 1016
Alarm 300799 appears ("Save boot

The commutation angle offset is determined as follows:
a) Select identification method via MD 1075. Possibly adapt other
machine data for rotor position identification.
b) Save the boot files and perform NCK reset.
c) Depending on which measuring system is used, continue as follows:
START
Are Hall sensor
boxes present?
If the enables are set, a rotor position identification
is carried out immediately.If the rotor position identi-
fication is unsuccessful, the appropriate error mes-
sage is output. Once the causes of the fault have
been eliminated and the error message acknowled-
ged, another attempt at identification is made.
Zero markers?
No zero marker, several zero mar-
kers without cam distance-coded
reference markers from up to VSA
06.07.07
There is no selection of the zero
marker and the commutation angle
offset is not accepted
End
6 Programming the control
No, Hall sensor boxes
not present
One zero marker
Set MD 1017 ("Start-up help") to 1
Move axis over the zero marker,
"JOG" operating mode
When it moves over the zero mar-
ker, the commutation angle offset
is entered in MD 1016
Alarm 300799 appears ("Save boot
