<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 unit the inverter is reset.

* When you have set write to RAM, powering off the inverter clears the parameter
values that have been changed. Therefore the parameter values available when
power is switched on again are those stored previously in E
When the parameter values will be changed frequently, set "1" in Pr. 342 to choose
write to RAM.

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 RESET input.

During a communication error (H0 to H5), the minor
(65535)
fault signal (LF) is switched on. Allocate the used
terminal with any of Pr. 190 to Pr. 192 (multi-function
outputs).
0 No communication
Set the communication check time [seconds] interval.
0.1 to
If a no-communication state persists for longer than the
999.8
permissible time, the inverter will come to an alarm stop.
9999 Communication check suspension
Set the waiting time between data transmission to the
0 to 150
inverter and response.
9999 Set with communication data.
