Write [1] to each bit corresponding to Forward rotation command (WS1) and Low speed operation command (WS3) of device SP122. The value will be 000AH in this example. When writing the value to device SP122 actually, convert 000AH to decimal number and write the value [10].
When using a WS device, [Alternate] of a bit switch cannot be used.
Use [Set], [Reset], and [Momentary] of a bit switch.
The following shows correspondences between virtual inverter devices used in the GOT and data of the inverter.
