Danfoss VLT5000 SyncPos Operating Instructions Manual page 151

■ ■ ■ ■ ■ SYNCCSTART
The command starts the movement of the slave.
With pnum, the point pair is selected that determines
in which master position the synchronization begins
and where it should be finished.
When moving forward, the synchronization begins at
point A and is finished up to point B. When moving
backward, it begins at point B and is finished up to
point A.
Summary
Start slave for synchronization in CAM-Mode
Syntax
SYNCCSTART pnum
Parameter
pnum =Start stop points number
pnum > 0 Engaging begins when the corre-
sponding point A is reached, provi-
ded the master moves in positive
direction; the engage curve is
finished at point B.
If point A and B are identical, the
slave will be engaged with the set
maximum velocity – i.e. without
curve – as soon as the master has
reached this point.
pnum = 0 The slave will be engaged imme-
diately with the set maximum velo-
city. It does not matter in what
direction the master moves or
whether it moves at all.
pnum < 0 Again, the corresponding point pair is
used, however, engaging begins at
point B and is finished at point A, i.e.
in negative direction.

■ ■ ■ ■ ■ SYNCCSTOP
This command stops synchronization without leaving
SYNCC mode. The slave will be disengaged
according to the point pair defined in pnum. Only
then will the slave actually be stopped. When the
stop point has been reached, the slave must be at
slavepos.
Summary
Stop slave after the CAM synchronization
Syntax
SYNCCSTOP pnum slavepos
Parameter
pnum = Start stop points number
pnum > 0 Engaging begins when the cor-
responding point A is reached,
provided the master moves in
positive direction; the engage
curve is finished at point B.
If point A and B are identical, the
slave will be engaged with the set
maximum velocity – i.e. without
curve – as soon as the master
has reached this point.
pnum = 0 The slave will be engaged imme-
diately with the set maximum
velocity. It does not matter in what
direction the master moves or
whether it moves at all.
pnum < 0 Again, the corresponding point
pair is used, however, engaging
begins at point B and is finished
at point A, i.e. in negative
direction.
slavepos = Position where the slave is supposed to
stand after disengaging.
NB!
When moving forward, disengaging begins at
point A and is finished at point B; vice versa
when moving backward.
NB!
If the program is closed without SYNCCSTOP
command, disengaging occurs by default with
the second point pair and a stop occurs at the Slave
Stop Position defined in the curve data.
