Goodrive350 IP55 High-ingress Protection Series VFD

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 of 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.
9.4.4.2 Addresses of other Modbus functions
In addition to modifying the parameters of the VFD, the master can also control the VFD, such
as starting and stopping the VFD, and monitoring the running status of the VFD. The following
table lists other function parameters.
