ued To
change
target
position
and
speed
smoothly Changing the tar-
get position and
target speed (fre-
quency) during
positioning (mul-
tiple start func-
tion) 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.
