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.)

6) Response time
