*1 In the communication request data from the computer to the inverter, 10ms or more is also required after "no data error (ACK)". (Refer to
page 217)
*2 The inverter response to the inverter reset request can be selected. (Refer to page 222)
*3 At mode error, and data range error, C1 data contains an error code. (Refer to page 226) Except for those errors, the error is returned with data
format D.

*3 When Pr.123 and Pr.337 (Waiting time setting) 9999, create a communication request data without "waiting time" in the data format. (The
number of characters decreases by 1.)
*4 CR, LF code
When data is transmitted from the computer to the inverter, codes CR (carriage return) and LF (line feed) are automatically set at the end of a
data group on some computers. In this case, setting must also be made on the inverter according to the computer. Whether the CR and LF
codes will be present or absent can be selected using Pr. 124 PU communication CR/LF selection.
