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.

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.
