5.5 BACKUP PARAMETERS
The CFW501 BACKUP functions allow saving the inverter current parameter contents in a specific memory
(EEPROM), or vice-versa overwrite the current parameters with the content of the specified memory.
P0204 – Load / Save Parameters
Adjustable
Range:
0...2 = Not Used
3 = Reset P0043
4 = Reset P0044
5 = Load WEG 60 Hz
6 = Load WEG 50 Hz
7 = Load user 1
8 = Load user 2
9 = Save user 1
10 = Save user 2
11 = Load Standard SoftPLC
12...15 = Reserved
Factory
Setting:
0
Properties: cfg
Description:
It allows saving the inverter present parameters in a non-volatile memory (EEPROM) of the control module or
the opposite, loading the parameters with the content of this area. Table 5.3: Option of parameter P0204 on
page 5-11 describes the actions performed
by each option.
Table 5.3: Option of parameter P0204
P0204 Action
0...2 Not Used: No action.
3 Reset P0043: resets the enabled hours counter.
4 Reset P0044: resets the kWh counter.
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 1: It transfers the content of the memory of parameters 1 to the inverter current parameters.
8 Load user 2: It transfers the content of the memory of parameters 2 to the inverter current parameters.
9 Saver user 1: It transfers the current content of the parameters to the memory of parameters 1.
10 Saver user 2: It transfers the current content of the parameters to the memory of parameters 2.
11 Load Standard SoftPLC: It loads the default values of the parameters SoftPLC applicative parameters.
12...15 Reserved: No Action
In order to load the parameters of user 1 and/or user 2 to the CFW501 operating area (P0204 = 7 or 8), it is
necessary that those areas be previously saved.
The operation of loading one of those memories (P0204 = 7 or 8) can also be done via digital inputs (DIx). For
further details referring to this programming, refer to section 12.5 DIGITAL INPUTS on page 12-15.
NOTE!
When P0204 = 5 or 6, parameters P0296 (Rated voltage), P0297 (Switching frequency) P0312 (Serial
Protocol) and P0308 (Serial address) are not changed to the factory default.
