and speed
smoothly
Change the
target posi-
tion and tar-
get speed
(frequency)
during posi-
tioning (mul-
tiple start
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-
not 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.
