ADJUSTMENT
Communication operation and setting — Initial setting of RS-485 communication
(Pr.117 to Pr.124, Pr.551)
Communication operation and setting — Control of parameter write by communication
(Pr.342)
117
PU communication
station number
1 0 0 to 31
Specify the inverter station number.
Set the inverter station numbers when two or
more inverters are connected to one personal
computer.
118
PU communication
speed
1192
48, 96, 192,
384
Set the communication speed.
The setting value ×
100 equals the
communication speed.
For example, the communication speed is
19200bps when the setting value is "192".
119
PU communication
stop bit length
11
Stop bit length data length
0 1bit 8bit
1 2bit 8bit
10 1bit 7bit
11 2bit 7bit
120
PU communication
parity check
12
0 Without parity check
1 With odd parity check
2 With even parity check
121
Number of PU
communication retries
11
0 to 10
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 trips.
9999
If a communication error occurs, the inverter
will not come to trip.
122
PU communication
check time interval
0.1s 9999
0 No PU connector communication
0.1 to 999.8s
Set the communication check time interval.
If a no-communication state persists for longer
than the permissible time, the inverter trips.
9999 No communication check
123
PU communication
waiting time setting
1 9999
0 to 150ms
Set the waiting time between data transmission
to the inverter and response.
9999 Set with communication data.
124

11
0 Without CR/LF
1With CR
2With CR/LF
342
