Goodrive390L Series Lift-Dedicated VFD
7.1.2.8.2 Example of writing command 06H
Example 1: Set the VFD whose address is 03H to run forward. According to the table of
address description of other function codes in section
Modbus functions, the parameter address of "communication-based control command"
is 2000H and forward running is 0001.
The command sent from the master is as follows:
03
VFD
address
If the operation is successful, the following response (same as the command transmitted
from the master) is returned:
03
VFD
address
Example 2: Set the max. output frequency to 100Hz for the VFD with the address of 03H.
Function code
P00.03 Max. output frequency P00.04–200.00H P00.04–200.00Hz 50.00Hz
According to the number of decimal places, the fieldbus scale of the "Max. output
frequency" (P00.03) is 100. Multiply 100 Hz by 100. The value 10000 is obtained, and it is
2710H in the hexadecimal form.
The command transmitted from the master is as follows:
03
VFD
address
If the operation is successful, the following response (same as the command transmitted
from the master) is returned:
03
VFD
address
Note: In the preceding command description, spaces are added to a command just for
explanatory purposes. In practical applications, no space is required in the commands.
