Change tar-
get position
Change the
target posi-
tion during
positioning
(multiple
start func-
tion)
PLS2(887) can be
executed during
positioning to
change the target
position (number of
pulses).
Note When the tar-
get position
cannot be
changed
without main-
taining the
same speed
range, an
error will
occur and the
original oper-
ation will con-
tinue to the
original tar-
get position.

Change the
target posi-
tion and tar-

(frequency)
during posi-
tioning (mul-

function)
PLS2(887) can be
executed during
positioning to
change the target
position (number of
pulses), accelera-
tion rate, decelera-
tion rate, and target
frequency.
Note When the
settings can-

without main-
taining the
same speed

error will
occur and the
original oper-
