2.12  Save set value 
Address    : D103 
Write authorisation  : ebm-papst, customer, end customer 
Encoding: 
This parameter specifies whether or not an incoming default set value (D001) is also stored in the EEPROM 
under set value (EEPROM) (D114 / D115). 
Value 
Function 
0 
Set value is not stored 
The fan is stationary after a reset 
1 
Set value is stored in EEPROM 
After reset, the fan will run with the stored set value 
The MSB is of no relevance! 
Permitted value range: 0 to 1 
The function must not be activated if the default set value is repeatedly write-accessed at 
frequent intervals (D001, see 2.3 Default set value)! 
If this instruction is not observed, there is a risk that the memory will be permanently 
destroyed. 
If the function is activated, the maximum number of times the default set value can be write 
accessed over the entire service life of the fan is 100,000. 
For more information, see the fan data sheet. 
2.13  Internal parameter set 
Address    : D105 
Write authorisation  : ebm-papst, customer, end customer 
Encoding: 
This parameter specifies whether parameter set 1 or parameter set 2 is used. 
Value 
Parameter set 
0 
Parameter set 1 
1 
Parameter set 2 
The MSB is of no relevance! 
Permitted value range: 0 to 1 
After this parameter is written, the new value becomes applicable immediately (no reset necessary).
