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.

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