14.2.2 Setting the Data Format

Code
E8.11 Modbus data format
0: 1 start bit, 8 data bits, 1 stop bit, no parity
●
1: 1 start bit, 8 data bits, 1 stop bit, even parity
●
2: 1 start bit, 8 data bits, 1 stop bit, odd parity
●
3: 1 start bit, 8 data bits, 2 stop bits, no parity
●
The data format of the converter must be the same as that of the
master station. Otherwise, normal communication is impossible.

14.2.3 Setting the Local Address

In Modbus communication, the maximum number of frequency converters in the
network is 247. Each frequency converter must have a unique local address.

14.2.4 Setting Command Signal Type

Code
Modbus level / edge sensitivity se-
E8.13
lection
Level sensitive (default situation): The control word is not a real edge sensitive,
master should manually reset the command.
For example:
1. Simulate an error
2. Set bit 5 = 1, the error is reset
3. Simulate an error again
4. Set bit 5 = 1, the error is not reset
5. Master should set bit 5 = 0 firstly, then set bit 5 = 1, the error is reset
Edge sensitive (selectable): The control command is reset automatically after
the activation.
For example:
1. Simulate an error
2. Set bit 5 = 1, the error is reset
3. Simulate an error again
4. Set bit 5 = 1, the error is reset
