For further details, refer to the installation, configuration and operation guide of the CFW300-IOADR I/O
expansion module.
5.2 BACKUP PARAMETERS
The CFW300 BACKUP functions allow saving the inverter current parameter contents in a specific memory (virtual
EEPROM - flash memory area of the microprocessor), or overwrite the current parameters with the content of
the specified memory.
P204 - Load / Save Parameters
Adjustable
Range:
0 to 4 = Not Used
5 = Load WEG 60 Hz
6 = Load WEG 50 Hz
7 = Load User
8 = Not Used
9 = Save User
10 = Not Used
11 = Load Default SoftPLC
12 and 13 = Reserved Factory
Setting:
0
Properties: cfg
Description:
Table 5.2 on page 5-4 describes the actions performed by each option.
Table 5.2: Option of parameter P204
P204 Action
0 to 4
Not Used:
no action
5
Load WEG 60 Hz:
it loads the default parameters on the inverter with the factory default for 60 Hz
6
Load WEG 50 Hz:
it loads the default parameters on the inverter with the factory default for 50 Hz
7 Load User: it transfers the content of the memory from user parameter to the inverter current parameters
8 Not Used: no action
9 Save User: it transfers the current content of the parameters to the memory of user parameters
10 Not Used: no action
11 Load Default SoftPLC: it loads the factory default in SoftPLC parameters (P910 to P959)
12 and 13 Reserved
In order to load the parameters of user to the CFW300 operating area (P204 = 7) it is necessary that this area
be previously saved.
The operation of uploading this memory (P204 = 7), can also be done via digital inputs (DIx). For further details
referring to this programming, refer to
Section 12.5 DIGITAL INPUTS on page 12-11 .
NOTE!
When P204 = 5 or 6, parameters P295 (Inv. Rated Current), P296 (Line Rated Voltage) and P308
(Serial Address) are not changed.
NOTE!
In order to upload the user parameters (P204 = 7), the factory default must be uploaded first
(P204 = 5 or 6).
