Chapter 5 Parameters_VFD-B Series
Revision 10/2005, BE13, SW V4.08 5-95
For example, communication to AMD with address 16 decimal (10H):
ASCII mode: Address=’1’,’0’ => ‘1’=31H, ‘0’=30H
RTU mode: Address=10H
3.3 Function (Function code) and DATA (data characters)
The format of data characters depends on the function code.
03H: read data from register
06H: write single register
08H: loop detection
10H: write multiple registers
The available function codes and examples for VFD-B are described as follows:
(1) 03H: multi read, read data from registers.
Example: reading continuous 2 data from register address 2102H, AMD address is 01H.
