Absolute Positioning with Continually Changing Target Position

The pulse output can be stopped by executing ACC(888) with a deceleration
target frequency of 0. However, since the pulse output cannot be stopped at
the correct number of pulses, the deceleration target frequency should not be
set to 0 if it is necessary to output a precise number of pulses.
This example performs absolute positioning (Electronic Cam Control) using a
single-phase pulse output without acceleration/deceleration, and the target
position is updated every cycle. This function relies on a constant cycle time,
in which the ladder program is executed every 2 ms, and positioning is per-
formed using a target value that is changed every cycle according to the
high-speed counter PV.
The pulse output is controlled by the target position, which is calculated
repeatedly from the high-speed counter PV. The target position is calculated,
so the APR instruction can be used for linear approximation.
The high-speed counter is set for circular operation with a circular value of
999 BCD.
