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.01-16. It should be noticed that the time
each step spends at its intended frequency is diminished, due to the time spent during accel/decel.

05 - 16 PLC Forward/Reverse Motion
Settings 00 to 32767 (0:Forward, 1:Reverse) Factory Setting: 00
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.
Note: The equivalent 15-bit number is used to program the forward/reverse motion for each of the 15
speed steps. The binary notation for the 15-bit number must be translated into decimal notation
and then entered.
