Parameter Name Function Description Setting Range Default
bd.01
Data format It is used to select the data format of the AC drive.
Note that the data format of the host computer must
be the same as that of the AC drive. Otherwise,
communication will fail.
0: No check <8, N, 2>
1: Even check <8, E, 1>
2: Odd check <8, O, 1>
3: No check <8, N, 1>
0 to 3 0
bd.02 Local address When it is set to 0 (broadcast address), the
broadcasting function of the host computer is
implemented. This address is unique (except the
broadcast address), which is the basis for point-to-
point communication between the host computer
and the AC drive.
0 to 247 1
bd.03 Response delay It is used to set the time interval from the AC drive
completing data receiving to AC drive sending
data to the host computer. If the response delay is
shorter than the system processing time, the system
processing time shall prevail. If the response delay
is longer than the system processing time, after
the system processing is completed, the AC drive
will not send data to the host computer until the
response delay is reached.
It is only valid for the RS485 communication.
0 to 20ms 2 ms
bd.04 Communication
timeout
If the time interval between two communications
is longer than the setting of bd.04, the AC drive
reports the 48# fault. Generally, it is set to 0.0s.
Set this parameter in the continuous communication
system to monitor the communication state.
If it is set to 0, fault 48# is shielded.
0.0s to 60.0s 0.0s
