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 trans-
mission 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.)
