Description
Procedure/
instruction
Starting
pulse output
To output
with spec-
ified
speed
Positioning
without accel-
eration or
deceleration
Starts outputting
pulses at the speci-
fied frequency and
stops immediately
when the specified
number of pulses
has been output.
Note
The target
position (spec-
ified number of
pulses) can-
not be
changed dur-

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

ON if the specified range for P, M, or F is exceeded.
ON if PLS2(887) or ORG(889) is already being executed
to control pulse output for the specified port.
ON if SPED(885) or INI(880) is used to change the mode
between continuous and independent output during pulse
output.
ON if SPED(885) is executed in an interrupt task when an
instruction controlling pulse output is being executed in a
cyclic task.
ON if SPEC(885) is executed in independent mode with
an absolute number of pulses and the origin has not been
established.
