Example 5 (Pr. 5-07 = d1 Execute one cycle of the PLC program): 

In this example, the PLC program runs continuously.  It should be noted that the times of reserve 

motion may be shorter than expected, due to the acceleration/deceleration times.

PLC Forward/Reverse Motion 

Unit: 1

 

Settings 

d0 to d255 

Factory Setting: d0

 

This parameter controls the direction of motion for the Multi-Step Speed Pr.5-00 to Pr.5-06 

and the Master Frequency.  The original direction of Master Frequency will become invalid. 

 

The equivalent 8-bit number is used to program the forward/reverse motion for each of the 8 speed 

steps (including Master Frequency). The binary notation for the 8-bit number must be translated into 

decimal notation and then be entered.
