The standard protocol only supports the register of 16 bits, and the above description is also based on the register of 16 bits. The parameters of MV300 series drive include both 16 bits (single character) and 32 bits (double characters). So, the data of both lengths shall be considered when reading/writing the parameters.

There are two types of drive parameters: one type of parameters adopts the decimal system and the other type is the variables adopting the hexadecimal system.
Page 247 The values returned in the reading operation are as shown in the following table: Register Access mode Value returned Description address 16-bit 0x1194 The actual value is returned. P01.01 The 16 high bits are filled with 0 and the actual value 32-bit 0x00001194 is returned.
Page 248 for the length expansion are as follows: expanding according to the highest bit of the 16-bit parameter value to be written, if the highest bit is 1, the 16 high bits will be filled with 0xFFFF, otherwise, they will be filled with 0x0000.

Page 250 the storage address of the first fault, this parameter and its following parameters cannot be changed normally, but the parameters before it can be written normally and the error message will be returned. 2. For some special function codes, 0x06 and 0x41 have the same function, and 0x10 and 0x43 have the same function.

4) The operation of the host device and that of the operation panel on the user password are independent, even if the operation panel has decrypted already, the host device still need to decrypt to access to the function code parameters, and vice versa. 5) When the host device gets the authority to access to parameters, it will read the user password and return to “0000”...
