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 FM/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).
Select the communication speed.
The setting value × 100 equals the communication
speed.
For example, enter 96 to set the communication speed
of 9600 bps.
Set a reference frequency of the set frequency.
Mitsubishi inverter protocol (computer link)
MODBUS RTU protocol
BACnet MS/TP protocol
Auto baud rate (bit 7)
0: inactive, 1: active
Max Master (bit 0 to bit 6) setting range: 0 to 127
Maximum address for master node
Set the maximum number of frames that the inverter
can transmit while it owns the token.
Device identifier
When the figure obtained by combining the Pr.728 and
Pr.729 settings 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".
