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).

REMARKS
When communication parameter n7 "waiting time setting" ‚ "- - -", create the
communication request data without "waiting time" in the data format. (The number
of characters is decremented by 1.)
