Goodrive200 inverters Communication protocol
236
See the figures behind the radix point, the fieldbus ratio value of the Max. output frequency
(P00.03) is 100. 100Hz timed by 100 is 10000 and the corresponding hex is 2710H.
The command sent by the master:
If the operation is successful, the response may be as below (the same with the command
sent by the master):
Note : the blank in the above command is for illustration. The blank can not be added in the
actual application unless the upper monitor can remove the blank by themselves.
Common communication fault
Common communication faults are: no response to the communication or the inverter
returns abnormal fault.
The possible reason for no response to the communication:
Selecting wrong serial interface, for example, if the converter is COM1, selecting COM2
during the communication
The baud rate, digital bit, end bit and check bit are not the same with the in and - of
RS485 are connected in reverse.
The 485 wire cap on the terminal board of the inverter is not plug in. the wire cap in behind
the terminal arrangement.
10.4.8.3 Example of continous writing command10H
Example 1: make the inverter whose address is 01H run forward at 10Hz. Refer to the
instruction of 2000H and 0001. Set the address of “communication setting frequency” is
2001H and 10Hz corresponds to 03E8H. See the table below.
