8.3 Planning Variable Speed Operation

This section introduces how to trigger many segments of speed (variable speed) in a fixed route by using
single-speed positioning mode.
8.3.1 Program structure
1. Trigger condition 1: external input signal. X0 ~ X3 switches to the 2
2. Trigger condition 2: comparison results of CP. M0 ~ M3 switches to the 2
3. Trigger condition 3: Timer. T0 ~ T3 switches to the 2
