Note:

The CSEL setting is not depended on setting between pins Band D.

Figure 3.14 CSEL setting

Figure 3.15 and 3.16 show examples of cable selection using unique interface

cables.

By connecting the CSEL of the master drive to the CSEL Line (conducer) of the

cable and connecting it to ground further, the CSEL is set to low level. The drive

is identified as a master drive. At this time, the CSEL of the slave drive does not

have a conductor. Thus, since the slave drive is not connected to the CSEL

conductor, the CSEL is set to high level. The drive is identified as a slave drive.
