BACnet MS/TP protocol

Using BACnet MS/TP protocol, communication operation and parameter setting are available from
the RS-485 terminals of the inverter.

When the set value is outside of the setting range, the initial value is applied.
When the Auto baudrate is used, the communication speed is changed to the detected commu-
nication speed.

The count of the setting values "82" and "83"
81 to 96, 98,
returns to "0" if the count exceeds "9999". The
100
upper limit of the count of the setting value
"84" is "9999".
0 Set the inverter station number (node).
0 to 127
Set the communication speed.
The setting value × 100 equals the
96, 192, 384,
96 communication speed.
576, 768, 1152
For example, the communication speed is 9600
bps when the setting value is "96".

When the combination of Pr.728 and Pr.729 is not
within "0 to 4194302", the setting is out of range.
Example:
When Pr. 728 = "419", setting range of Pr. 729 is "0
0 to 9999
0
to 4302".
(0 to 4302)
When Pr. 729 = "4303" or more, setting range of
Pr. 728 is "0 to 418".
