ACC
Continuous Mode Speed Control
Pulse output will continue until it is stopped from the program.
Note Pulse output will stop immediately if the CPU Unit is changed to PROGRAM mode.

Starting
pulse out-
put
To output
with speci-
fied acceler-
ation and
speed
Accelerating the
speed (frequency)
at a fixed rate
Outputs pulses and
changes the frequency at
a fixed rate.
ACC(888)
(Continuous)
Chang-
ing set-
tings
To change
speed
smoothly
Changing the
speed smoothly
during operation
Changes the frequency
from the present fre-
quency at a fixed rate.
The frequency can be
accelerated or deceler-
ated.
ACC(888) or
SPED(885)
(Continuous)
ACC(888)
(Continuous)
Changing the
speed in a polyline
curve during oper-
ation
Changes the accelera-
tion or deceleration rate
during acceleration or
deceleration.
ACC(888)
(Continuous)
ACC(888)
(Continuous)
Decelerating to a
stop
The deceleration rate is
changed while decelerat-
ing.
Note If the target fre-
quency is set to 0
Hz, the current
deceleration rate
will be used.

Decelerated pulse out-
put to a stop.
Note If the target fre-
quency of the sec-
ond ACC(888)
instruction is 0 Hz,
the deceleration
rate from the first
ACC(888) instruc-
tion will be used.
