Definition of communication parameter addresses:
The parameters can be read and written (except those which cannot be changed
because they are only for factory use or monitoring).

This parameter defines the rate of data transmission
between the host controller and the AC drive. A higher
baud rate indicates faster communication.
Note that the baud rate of the host controller must be the
same as that of the AC drive. Otherwise, communication
will fail.
FD‑01 RS485 data
format
0 0: No check (8‑N‑2)
1: Even parity check (8‑E‑
1)
2: Odd parity check (8‑O‑
1)
3: No check (8‑N‑1)
4: No check (7‑N‑2)
5: Even parity check (7‑E‑
1)
6: Odd parity check (7‑O‑
1)
7: No check (7‑N‑1) (valid
for Modbus)
Note that the data format set in the host controller must
be the same as that set in the AC drive. Otherwise,
communication will fail.
