5) Waiting time
Specify the waiting time between the receipt of data at the inverter from the computer and the transmission
of reply data. Set the waiting time in accordance with the response time of the computer between 0 and
150ms in 10ms increments (e.g. 1 = 10ms, 2 = 20ms).

Note: If the Pr. 123 "waiting time setting" value is not 9999, create the communication request data with no
"waiting time" in the data format. (The number of characters is decremented by 1.)
