0.0 s (invalid)
0.1 ~ 60.0s
When the function code is set to 0.0 s, the communication timeout parameter is invalid.
When the function code is set to a valid value, if the interval between one communication and the next exceeds
the communication timeout, the system will report a communication timeout (Err44). Usually, it is set to
invalid.
Response delay: it refers to the interval between the end of data receiving of inverter and the sending of data to
upper computer. If the response delay is less than the system processing time, the response delay is subject to
the system processing time. If the response delay is longer than the system processing time, the system will wait
until the response delay time reached, and then send the data to the upper computer.
Communication interruption
detection of expansion card
When the function code is set to 0.0s, the expansion card communication interruption detection parameter is
invalid.
When the function code is set to valid value, if the communication time between the inverter and the expansion
card exceeds the value set by the expansion card communication interruption detection (P9-06), the system will
report an error communication timeout (Err44). The default setting is 0.

PA-01 is used to select the target given channel of process PID. PA-02 is used to select the feedback channel of
process PID.
The setting target value of process PID is relative value, and the setting range is 0.0% ~ 100.0%. Similarly, the
feedback quantity of PID is also relative quantity, and the goal of PID is to make the two relative quantities the
