I I I I I DEC
The DEC command defines the deceleration for
the next motion command (speed control, synchro-
nization or positioning). The value will remain valid
until a new deceleration value is set with another
DEC command. The value is related to the para-

NB!
If you work with the SyncPos option card
then you should always set the ramps via
the option card and not in the VLT. The VLT ramps
must always be set to minimum.

I I I I I DEFMORIGIN
DEFMORIGIN defines the current master position
as the zero point for the master. The master
position (MAPOS) refers to this zero point until a
redefinition takes place using DEFMORIGIN or
SETMORIGIN.
Summary
Set the current master position as the zero point
for the master.

DEFMORIGIN
/* Set current position as the zero point for the
master */
I I I I I DEF ORIGIN
With the DEF ORIGIN command the current
position is set as the zero point. All absolute
positioning commands (POSA) then refer to this
zero point.
