Positioning with
trapezoidal accel-
eration and
deceleration
(Separate rates
used for acceler-
ation and decel-
eration; starting
speed)
The number of
pulses can be
changed during
positioning.
Accelerates and decel-
erates at a fixed rates.
The pulse output is
stopped when the
specified number of
pulses has been out-
put. (See note.)
Note The target posi-
tion (specified
number of
pulses) can be
changed during
positioning.

speed
smoothly
(with
unequal
accelera-
tion and
decelera-
tion rates)
Changing the tar-
get speed (fre-
quency) during
positioning
(different acceler-
ation and decel-
eration rates)
PLS2(887) can be exe-
cuted during position-
ing to change the
acceleration rate,
deceleration rate, and
target frequency.
Note To prevent the
target position
from being
changed inten-
tionally, the origi-
nal target
position must be
specified in
absolute coordi-
nates.

Changing the tar-
get position dur-
ing positioning
(multiple start
function)
PLS2(887) can be exe-
cuted during position-
ing to change the
target position (num-
ber of pulses), acceler-
ation rate, deceleration
rate, and target fre-
quency.
Note If a constant
speed cannot be
maintained after
changing the set-
tings, an error
will occur and
the original oper-
ation will con-
tinue to the
original target
position.
