<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
communication cannot be made unit 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 coasted to a stop by MRS or RES input.
9999
During a communication error (H0 to H5), the minor
(65535)
fault signal (LF) is switched on. Assign the used
terminals with Pr. 192 "A, B, C terminal (ABC) function
selection".
0 No communication
Set the communication check time [seconds] interval.
If a no-communication state persists for longer than
0.1 to 999.8
the permissible time, the inverter will come to an
alarm stop.
9999 Communication check suspension
Set the waiting time between data transmission to
0 to 150
the inverter and response.
9999 Set with communication data.
