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.

5-08 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.
NOTE
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.
