ACC(888) outputs pulses to the specified output port at the specified fre-
quency using the specified acceleration and deceleration rate. (Acceleration
rate is the same as the deceleration rate.) Either independent mode position-
ing or constant mode speed control is possible. For positioning, ACC(888) is
used in combination with PULS(886). ACC(888) can also be executed during
pulse output to change the target frequency or acceleration/deceleration rate,
enabling smooth (sloped) speed changes.
