3. Instructions
ACC(888) can also be used to change settings during pulse output. ACC(888) in independent mode
can also be executed during pulse output for PLS2(887) during acceleration, constant speed, or
deceleration. With the CJ1M and CJ2M CPU Units, PLS2(887) can be executed during pulse output for
ACC(888) in either independent or continuous mode, and during acceleration, constant speed, or
deceleration. (See note 1.)
Note Executing PLS2(887) during speed control with ACC(888) (continuous mode) with the same target fre-
quency as ACC(888) can be used to achieved interrupt feeding of a fixed distance. Acceleration will not be
performed by PLS2(887) for this application, but if the acceleration rate is set to 0, the Error Flag will turn ON
and PLS2(887) will not be executed. Always set the acceleration rate to a value other than 0.
