<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 if the inverter is not 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.

During an error, the light fault signal (LF) is given to
(65535)
the open collector output. Allocate the used terminal
with any of Pr. 190 to Pr. 192 (Output (remote input)
function selection).
0 No communication
Set the communication check time [seconds]
interval.
0.1 to 999.8 If a no-communication state persists for longer than
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.
