Protocol selection (y10, y20)

y10 specifies the communications protocol
for port 1.
For FRENIC Loader (via the RS-485
communications link), only y10 can be used
for protocol selection. Set the y10 data at
"1."
y60, y61 BACnet Device instance number (Upper and Lower)
These function code are available at ROM version 2100 or later.
These settings specify Device instance number for identifying itself on the application layer
of BACnet protocol.
Setting method is different by y61 setting value as below:
Data for y61
128 to 999
*1 Maximum setting range for device instance number is: 0 to 4194302.
*2 MAC address is specified by y01 or y11.
y95 Data Clear Processing for Communications Error
Data for y95
* Related alarms: Er8, ErP, Er4, Er5
Device instance number
0 (y60 * 1000) + MAC address
(y60 * 1000) + y61
Do not clear the data of function codes Sxx when a
0 communications error occurs. (compatible with the conventional
inverters)
Clear the data of function codes S01/S05/S19 when a
1
communications error occurs.
Clear the run command assigned bit of function code S06 when a
2
communications error occurs.
Clear both data of S01/S05/S19 and run command assigned bit of
3
S06 when a communications error occurs.
