PARAMETERS
122
<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.

Set the permissible number of retries at occurrence of
a data receive error.
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
fault signal (LF) is switched on. Allocate the used
terminal with any of Pr. 190 to Pr. 192 (multi-function
outputs).
0 No communication
0.1 to 999.8
Set the communication check time [seconds] interval.
If a no-communication state persists for longer than
the permissible time, the inverter will come to an
alarm stop.
