Starting
pulse out-
put
Complex
trapezoidal
control
Positioning with
trapezoidal accel-
eration and decel-
eration (Separate
rates used for
acceleration and
deceleration; start-
ing speed)
The number of
pulses can be
changed during
positioning.
Accelerates and deceler-
ates at a fixed rates. The
pulse output is stopped
when the specified num-
ber of pulses has been
output. (See note.)
Note The target position
(specified number
of pulses) can be
changed during
positioning.

(with
unequal
accelera-
tion and
decelera-
tion rates)
Changing the tar-
get speed (fre-
quency) during
positioning
(different accelera-
tion and decelera-
tion rates)
PLS2(887) can be exe-
cuted during positioning
to change the accelera-
tion rate, deceleration
rate, and target fre-
quency.
Note To prevent the tar-
get position from
being changed
intentionally, the
original target posi-
tion must be speci-
fied in absolute
coordinates.

Changing the tar-
get position during
positioning (multi-
ple start function)
PLS2(887) can be exe-
cuted during positioning
to change the target
position (number of
pulses), acceleration
rate, deceleration rate,
and target frequency.
Note If a constant speed
cannot be main-
tained after chang-
ing the settings, an
error will occur and
the original opera-
tion will continue to
the original target
position.
