2.4 Password
Address : D002 - D004
Write authorisation : ebm-papst, customer, end customer
Encoding:
bytes DataPassword
In order to prevent unauthorised writing of certain parameters, these are only written if the correct password
for the necessary authorisation is entered at this point.
If a user forgets to reset the password, it will automatically be reset to 0x000000000000 after 4 minutes of
inactivity.
When the "Password" parameter is read, the value 0 is always output to prevent a user with a lower
authorisation level gaining access to a password to a higher level.

Error
D -> W
W -> D
Setting the bit D -> W causes all parameters in the data range (D100 to D17F) to be copied to the default
setting (range D280 to D2FF).
The authorisation level "ebm-papst" is needed to set this bit!
Setting the bit W -> D causes all parameters in the default setting (D280 to D2FF) to be copied to the data
range (range D100 to D17F).
The authorisation level "customer" is sufficient to set this bit.
Once the copying process is complete, the bit will automatically be reset by the fan.
Important!
A copy procedure can only be carried out after the fan has stopped.
Otherwise the "Error" bit will be set and the copy procedure aborted.
