# For the data codes of the parameters, refer to the data code list in the appendices.
REMARKS
For computer link operation, set the value "8888" as 65520 (HFFF0) and the value "9999" as 65535
(HFFFF).

<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.

are connected to one personal computer.

Set the permissible number of retries at occurrence of 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 RES 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. 195 (output
terminal function selection).
No communication
Set the communication check time [s] interval.
If a no-communication state persists for longer than the permissible time, the
inverter will come to an alarm stop.
Set the waiting time between data transmission to the inverter and response.
Set with communication data.
