13.2.1 Common Settings for Communication Option Board
 How to continue operation even when a communication error is detected between the inverter
main unit and the option board?
 How to specify the behavior of the inverter when a communication error with the host device
occurs when using the communication option?
 Set the inverter operation when an error occurs in the data transfer between the option board
and the inverter main unit using "Operation selection at an option error [P001]". Normally, use
with "Trip (00)".
 When using the communication option, set the timeout time for detecting communication time-
out with the host device and the inverter operation when timeout occurs in "Communication
Watch Dog Timer [P044]" and "Operation selection at option communication timeout [P045]",
respectively. Set them properly according to the system.
 If run/stop command is given through the option board when "Continued operation (01)" is set
to "Operation selection at an option error [P001]", it may not be possible to stop from the option
board. Be careful to have a system configuration that can be stopped.
