5.14 Parameter Storage
5.14.1 Command Parameters
The saving and loading of parameters to the Non-Volatile Memory (NVM) of the drive is implemented using three
parameters, and a number of bit fields. The three relevant parameters are listed below: -
Index Type Name
0x2141/0 U08 nvm_load_parameters
0x2142/0 U08 nvm_save_parameters
0x2143/0 U08 load_default_parameters
Table 5.44 List of NVM related parameters
5.14.2 Storage Types
Each parameter is assigned a storage type that defines the area of NVM to which it is stored. The storage types are:
-
• None: - parameter is not saved to NVM
• Fac: - Factory types are used to hold parameters which are set during drive manufacture, not for general
user.
• Ext:- Extended types are used to hold baud rates, parity etc
• Cus: General / Customer types are placed in a general area used to hold parameters set by the user.
• Enc: Encoder types are stored in the encoder EEPROM and
also in the ‘Cus’ storage area
When a load or save is performed, the user defines the storage type of the parameters to be saved or loaded, by
setting the appropriate bit(s) in the parameter.
5.14.3 Data Group
Each parameter is assigned to a particular data group. The two groups are: -
• App : Application profile parameters
• Com :- Communication parameters
When a load or save is performed, the user defines the data group of the parameters to be saved or loaded, by setting
the appropriate bit(s) in the parameter. The bit mask for selecting the appropriate storage type, and data group is
shown below :-
