■ ■ ■ ■ ■ MOTOR STOP
By using the MOTOR STOP command, a drive in
positioning, speed or synchronizing mode can be
decelerated with programmed acceleration and
arrested at the momentary position.
A drive arrested with this command can, at a later
point, via the CONTINUE command, resume its
original motion. (Exception: CONTINUE does not
continue an interrupted synchronization command.)
NB!
If MOTOR STOP is executed in a subprogram
or if NOWAIT is set to ON, then the next lines
in the program are already processed while MOTOR
STOP is being processed; the braking process runs
in the background.
Therefore, in order to slow the drive down to a speed
of zero it is necessary to ascertain that no new
positioning command is given during braking.

■ ■ ■ ■ ■ MOVESYNCORIGIN
The command shifts the origin of synchronization
in relation to the master. While SET
SYNCPOSOFFS sets the offset position absolutely,
MOVESYNCORIGIN always relates to the last one
and shifts the offset position relatively. If you have
to shift the offset position continually, you can pre-
vent too large numbers or an overflow in this way.
