Goodrive200 inverters
Communication protocol
227
the loop detection to address 01H of driver is carried out.
The RTU request command is:
START T1-T2-T3-T4 (transmission time of 3.5 bytes)
ADDR 01H
CMD 08H
High bit of sub-function code 00H
Low bit of sub-function code 00H
High bit of data content 12H
Low bit of data content ABH
Low bit of CRC ADH
High bit of CRC 14H
END T1-T2-T3-T4 (transmission time of 3.5 bytes)
The RTU response command is:
START T1-T2-T3-T4 (transmission time of 3.5 bytes)
ADDR 01H
CMD 08H
High bit of sub-function code 00H
Low bit of sub-function code 00H
High bit of data content 12H
Low bit of data content ABH
Low bit of CRC ADH
High bit of CRC 14H
END T1-T2-T3-T4 (transmission time of 3.5 bytes)
10.4.4 Command code: 10H, continuous writing
Command code 10H means that if the master writes data to the inverter, the data number
depends on the “data number” in the command code. The Max. continuous reading number
is 16.
For example, write 5000(1388H) to 0004H of the inverter whose slave address is 02H and
50(0032H) to 0005H, the frame structure is as below:
The RTU request command is:
START T1-T2-T3-T4 (transmission time of 3.5 bytes)
ADDR 02H
CMD 10H
