Changing
the target
speed (fre-

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

PLS2 can be exe-
cuted during posi-
tioning to change
the target position
(number of pulses).
When the target
position cannot be
changed without
maintaining the
same speed range,
an error will occur
and the original
operation will con-
tinue to the original
target position.
