* When making communication, set any value other than 0 in Pr. 122 "communication
check time interval".
<Setting>
To make communication between the personal computer and inverter, the
communication specifications must be set to the inverter initially. If initial setting is not
made or there is a setting fault, data transfer cannot be made.
Note: After making the initial setting of the parameters, always reset the inverter. After
you have changed the communication-related parameters, communication
cannot be made until the inverter is reset.

Set the permissible number of retries at occurrence of
a data receive error.
0 to 10 If the number of consecutive errors exceeds the
permissible value, the inverter will come to an alarm
stop.
If a communication error occurs, the inverter will not
come to an alarm stop. At this time, the inverter can be
9999 coasted to a stop by MRS or RES input.
(65535) During a communication error (H0 to H5), the minor fault
signal (LF) is switched on. Allocate the used terminal
with any of Pr. 190 to Pr. 192 (multi-function outputs).
