Changing
settings
To change
speed
smoothly
(with
unequal
acceleration
and
deceleration
rates)
Changing the
target speed
(frequency) during
positioning
(different
acceleration and
deceleration rates)
PLS2(887) can be
executed during
positioning to change the
acceleration rate,
deceleration rate, and
target frequency.
Note To prevent the
target position from
being changed
intentionally, the
original target
position must be
specified in
absolute
coordinates.

To change
target
position
Changing the
target position
during positioning
(multiple start
function)
PLS2(887) can be
executed during
positioning to change the
target position (number
of pulses), acceleration
rate, deceleration rate,
and target frequency.
Note With the CJ1M or
when operation
compensation for
parameter
changes is not
enabled with the
CJ2M, an error will
occur and the
original operation
will continue to the
original target
position if a
constant speed
cannot be
maintained after
changing the
settings.
