Indicates the data such as frequency and parameters transferred to and from the inverter. The definitions and ranges of
set data are determined in accordance with the instruction codes. (Refer to
• 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 in the range of 0 to 150 ms in 10 ms increments.
(For example; 1 = 10 ms, 2 = 20 ms)
When Pr.123 or 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.)
When Pr.123 = "9999", the waiting time is the data setting value × 10 ms. When Pr.123 ≠ "9999", the waiting time is the value set in Pr.123.
The time is about 10 to 30 ms. It varies depending on the instruction code.
• The data check time varies depending on the instruction code. (Refer to
• Sum check code
The sum check code is a 2-digit ASCII (hexadecimal) representing the lower 1 byte (8 bits) of the sum derived from the
checked ASCII data.

• Error code
If any error is found in the data received by the inverter, its error definition is sent back to the computer together with the
