Changing
the target
speed (fre-
quency) dur-
ing
positioning
(different
acceleration
and deceler-
ation rates)
PLS2(887) can be
executed during
positioning to
change the acceler-
ation rate, decelera-
tion rate, and target
frequency.
Note To prevent
the target
position from
being
changed
intentionally,
the original
target posi-
tion must be
specified in
absolute
coordinates.

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.
