Example 3 (Pr.05-15 = 3) Execute one cycle step by step:
The example below shows how the PLC can perform one cycle at a time, within in a complete
cycle. Each step will use the accel/decel times in Pr.01-09 to Pr.01-12. It should be noticed
that the time each step spends at its intended frequency is diminished, due to the time spent
during accel/decel.

This parameter controls the direction of motion for the Multi-Step Speeds Pr.05-00 to
Pr.05-14 during PLC mode. All other direction commands are invalid during the PLC
mode.
