(N) Operation via communication and its settings Parameters
5 - 632
Waiting time setting from the communication line error occurrence to the communication error
activation (Pr. 500)
●
When a communication option is used, use Pr. 500 "Communication error execution waiting time"
to set the time from when the communication line error occurs until the inverter starts the
operation for the communication error.
●
When a communication line error occurs and lasts longer than the time set in Pr. 500, it is
recognized as a communication error. If the communication returns to normal within the time, it
is not recognized as a communication error, and the operation continues.
●
Operation from the error occurrence until the Pr. 500 setting time elapses
When the communication returns to normal within the time period set in Pr. 500, the communi-
cation option error (E.OP1) does not occur.
