Example 2 (Pr.05-15 = 2): Continuously execute program cycles:

The diagram above shows the PLC program stepping through each speed. Setting Pr.05-15 to 2

continuously executes the program. To stop the PLC program, one must either pause the program or

turn it off. (Refer to Pr.04-04 to 04-09 values 14 and 15).

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 a complete cycle.

Each step will use the accel/decel times in Pr.01-09 to Pr.01-12. Note that the actual time each step

stays at its intended frequency is reduced, due to the time for accel/decel.

Settings

00 to 32767

Unit: 1

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.
