Description of parameters
3.4.4 Operation selection of SOF signal and OH signal (Pr. 8, Pr. 9)
<SOF signal input status and Pr. 8 setting for the converter operation >
The converter does not operate at the Pr. 8 = "1" (NC contact) setting while FR-A7NC is not mounted. Set Pr. 8 = "2" (NC contact for external signals, NO
contact for CC-Link communication).
<OH signal input status and Pr. 9 setting for the converter operation >
Operation of SOF signal can be changed by the Pr. 8 setting, and OH signal by the Pr. 9 setting.
