■ ■ ■ ■ ■ 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-
meters Shortest ramp Shortest ramp RAMPMIN (31) and Shortest ramp Shortest ramp

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.

■ ■ ■ ■ ■ DEFMCPOS
DEFMCPOS defines the initial position of the
master (in MU) in the CAM-Mode and thus the
point where the curve begins as soon as the
master pulses are being counted.
