Description
81: BACnet reception status
82: BACnet token pass counter (Displays the count of
received token)
83: BACnet valid APDU counter (Displays the count of valid
APDU detection)
84: BACnet communication error counter (Displays the count
of communication error)
85: Terminal CA output level (Same display as Analog Output
0)
86: Terminal AM output level (Same display as Analog Output
1)
The count of the setting values "82" and "83" returns to "0" if
the count exceeds "9999". The upper limit of the count of the
setting value "84" is "9999".
Set the inverter station number (node).
Set the communication speed.
The setting value  100 equals the communication speed.
For example, the communication speed is 9600 bps when the
setting value is "96".
Set a reference frequency of the set frequency.

Set the maximum number of frames that the inverter can
transmit while it owns the token.
Device identifier
When the combination of Pr.728 and Pr.729 is not within "0 to
4194302", the setting is out of range.
When Pr.728="419", the setting range of Pr.729 is "0 to 4302".
When Pr.729="4303" or more, the setting range of Pr.728 is
"0 to 418".
