Danfoss VLT 5000 Operating Instructions Manual page 26

Active set up (ACTIVE SETUP)
Function:
Like parameter 005 (described in the product
manual for the VLT 2800 series).
Description of choice:
It is only possible to write to the active set-up via
DeviceNet in the VLT 2800/FCD 300. This means
that it is not possible to run for instance in set-up
1 and change data in set-up 2, 3 or 4.
971 Save date values
(STORE DATA VALUE)
Value:
Not active (OFF)
Save active setup (STORE ACTIVE SETUP)
Save edit setup (STORE EDIT SETUP)
Save all setups (STORE ALL SETUPS)
Store Always (STORE ALWAYS)
Function:
Parameter values modified through DeviceNet are
only saved in RAM, i.e. the modifications are lost
in the event of a power failure. This parameter is
used to activate a function by means of which all
parameter values are saved in EEPROM, preserving
them even in the case of a power failure.
Description of choice:
- Not active: The function is not active.
- Save active setup: All parameter setups of
the active setup are saved in EEPROM. The
value returns to Not active after all parameter
values have been saved.
- Save edit setup: All parameter setups of the
setup being processed are saved in EEPROM.
The value returns to Not active after all parameter
values have been saved.
- Save all setups: All parameter setups in all setups
are saved in EEPROM. The value returns to Not
active after all parameter values have been saved.
- Store Always: Each parameter write request will
automatically be stored in EEPROM.
NB!:
Please note that continous writing via explicit
message may damage the EEPROM.

980–982 Defined parameters
[ 5]
(DEFINED PARAM.)
Value:
Read only
Function:
The three parameters contain a list of all parameters
defined in the VLT. Each of the three parameters can
be read as an array by means of a explicit message.
Each parameter contains up to 116 elements
(parameter numbers). The number of parameters
that are in use (980, 981 and 982) depends on
the respective VLT configuration.
When a 0 is issued as a parameter number, the list ends.
[0]
[1]
990–992 Modified parameters
[ 2]
(MODIFI. PARAM.)
[ 3]
Value:
[ 4]
Read only
Function:
The three parameters contain a list of all parameters
that have been changed from the factory setting.
Every one of the three parameters can be read as an
array with the help of the explicit read service. The
subindices begin with 1 and follow the sequence of
the parameter numbers. Each parameter contains up
to 116 elements (parameter numbers). The number
of parameters that are in use (990, 991 and 992)
depends on how many parameters have been modified
in comparison with the factory setting.
Pure read parameters (Read only), such as data
output parameters, are not logged as modified
even if they are changing.
When a 0 is issued as a parameter number, the list ends.
