Drive K120 series
Note:
The parameters in the P29 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.
7.4.2 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 stopping it, and monitoring the operation status of the VFD. The
following table describes other function parameters.
