Changing
the speed in
one step dur-
ing operation
SPED(885) can be
executed during
positioning to
change (raise or
lower) the pulse
output frequency in
one step.
The target position
(specified number
of pulses) is not
changed.

ACC(888) can be
executed during

rate and target fre-
quency.
The target position
(specified number
of pulses) is not
changed.

PLS2(887) can be
executed during
positioning to
change the acceler-

Note To prevent
the target
position from
being
changed
intentionally,
the original
target posi-
tion must be
specified in
absolute
coordinates.
