INVT Goodrive200A Series User Manual

GD200A series VFD Communication protocol
-139-
Besides, EEPROM is stocked frequently, which may shorten the usage time of EEPROM. For users,
some functions are not necessary to be stocked on the communication mode. The needs can be
met on by changing the value in RAM. Changing the high bit of the function code form 0 to 1 can
also realize the function. For example, the function code P00.07 is not stocked into EEPROM. Only
by changing the value in RAM can set the address to 8007H. This address can only be used in
writing RAM other than reading. If it is used to read, it is an invalid address.
9.5.2 The address instruction of other function in MODBUS
The master can operate on the parameters of the VFD as well as control the VFD, such as running
or stopping and monitoring the working state of the VFD.
