Chap. 9 FUNCTION CODES
Communications error processing (y02)
Specifies the error processing operation for RS-485 communication.
Data for y02 The inverter will:
0
Immediately enter Alarm mode, issue RS-485 communications error
GT
and
shut down its output.
1
Continue to run for the period preset by the timer, then enter Alarm mode, issue
RS-485 communications error
GT
, and shut down its output.
2
Retry to receive/send the query/response during the period preset by the timer.
If communications have not recovered, the inverter will enter Alarm mode, issue
RS-485 communications error
GT
and shut down its output. If
communications have recovered, the inverter will continue to run.
3 Continue to run even if a communications error occurs.
• Setting for FRENIC Loader: If the connected PC runs out during test-running of the
inverter, no stop command may be able to be sent to stop the inverter. For safety, select the
setting for this function code so as to prevent this happening.
Error processing timer (y03)
Sets the error processing timer (for waiting time)
- Data setting range: 0.0 to 60.0 (sec.)
Transmission speed (y04)
Data for y04 Transmission speed
0 2400 bps
1 4800 bps
2 9600 bps
Selects the transmission speed for RS-485
communication.
- Setting for FRENIC Loader: Set the same
transmission speed as that specified for the
connected PC.
3 19200 bps
Transmission data length (y05)
Data for y05 Data length
0 8 bits
1 7 bits
Select the character data for transmission.
Setting for FRENIC Loader:
The loader will set the length in 8 bits
automatically. (The same applies to the
Modbus RTU.)
Parity check (y06)
Data for y06 Parity
0 No parity bit
1 Even parity
Select the property of the parity bit.
- Setting for FRENIC Loader:
The loader automatically sets it to the even
parity.
2 Odd parity
