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.

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.
