Note:
The parameters in the P99 group are set by the manufacturer and cannot be read or modified.
Some parameters cannot be modified when the VFD is running; some cannot be modified
regardless of the VFD status. Pay attention to the setting range, unit, and description of a
parameter when modifying it.
The service life of the Electrically Erasable Programmable Read-Only Memory (EEPROM) may
be reduced if it is frequently used for storage. Some function codes do not need to be stored
during communication. The application requirements can be met by modifying the value of the
on-chip RAM, that is, modifying the MSB of the corresponding function code address from 0 to 1.
For example, if P00.07 is not to be stored in the EEPROM, you need only to modify the value in
the RAM, that is, set the address to 8007H. The address can be used only for writing data to the
on-chip RAM, and it is invalid when used for reading data.
10.4.5.2 Description of other function addresses
In addition to modifying the parameters of the VFD, the master can also control the VFD, such as
starting and stop it, and monitoring the operation status of the VFD. The following table describes
other function parameters.
