Note 1: ON usually when either the control circuit terminal board or a coil is ON. Among intelligent input terminals, the control circuit terminal board is a high- priority terminal. If the master cannot reset the coil ON status due to a transmission line break, turn ON and OFF the control circuit terminal board to make the coil OFF status.

Note 2: The content of a transmission error is held until the error is reset. (The error can be reset while the inverter is running.)
