2.3 Default set value
Address : D001
Write authorisation : ebm-papst, customer, end customer
The "Default set value" parameter is used in MODBUS to specify a set value for each control mode.
The condition for this is that the "Source set value" RS485 (1) is specified (see 2.10 Source set value).
Otherwise, the parameter will have no function.
If the "Store" function is activated in the "Store set value" parameter (see 2.12 Save set value),, the value in
the set value parameter (EEPROM) will be stored every time the default set value is write-accessed (see 2.19
Set value (EEPROM)).
The "Store set value" function must not be activated if the default set value is repeatedly
write-accessed at frequent intervals!
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.
The "Internal parameter set" parameter is used to select whether the value is stored in "Set value (parameter
set 1)" or in "Set value (parameter set 2)" (see 2.13 Internal parameter set).
Following a reset, the motor will again run with this value, provided the parameter set selection has not been
changed. (see 2.12 Save set value)
Important!
If the "Store set value" function is activated and the parameter set is changed (from 1 to 2 or vice versa), the
default set value will automatically be changed to the corresponding parameter "Set value (parameter set 1)"
or "Set value (parameter set 2)"!
Encoding:
Note: The 4 LSBits are of no relevance for the set value and will always be assumed to be 0.
