Figure 7.3 Example of reading read-only parameters
Figure 7.4 Operation example of modifying parameters
In the function parameter display state, if the parameter has no flashing bit, it means that the function code
cannot be modified, and the possible reasons are as follows:
(1) This function code is an unmodifiable parameter. Such as actual detection parameters, operation record
parameters, etc.;
(2) This function code cannot be modified in the running state, and can only be modified after stopping
the machine;
(3) Parameters are protected. When the function code F7.03 is 1 or 2 , the function code cannot be modified.
This is to protect the parameters from misoperation. For details, refer to the description of F7.03.
Example 2: modify parameters
When modifying parameters, take modifying the set frequency F0.05 as an example, modify 50.00Hz to
30.00Hz. The operation steps are as shown in Figure 7.4, and the operation methods of other modifiable
parameters can be deduced in the same way :
