Table 7-38 NV Media Card operation and back-up
7.25.1 Saving parameter set to NV Media Card
•
4yyy
- Saves all default differences to the NV Media Card
The data block only contains the parameter differences from the last time the default settings were loaded. All parameters except those with the NC
Not copied) coding bit set are transferred to the NV Media Card.
•
N01 = Program (2)
- Saves parameter set to the NV Media Card
Setting
Parameter Cloning Modes
(
N01
) to Program (2) and resetting the drive will save the parameters to the NV Media Card this is the equivalent of
writing 4001 to Pr
mm00
. If the data block already exists, it is automatically overwritten. When the action is complete this parameter is automatically
reset to None 0).
7.25.2 Reading parameter set from NV Media Card
•
Parameter N01 = Read (1)
Setting
Parameter Cloning Modes
(
N01
) to Read (1) and resetting the drive will transfer the parameters from the NV Media Card into the drive
parameter set and the drive EEPROM, i.e. this is equivalent to writing 6001 to Pr
mm00
. Once the parameters are successfully copied this parameter
is automatically reset to None (0). Parameters are saved to the drive EEPROM after this action is complete.
7.25.3 Auto saving parameters to NV Media Card
•
Parameter N01 = Auto (3)
This setting automatically saves any changes made to User Menu A parameter set to the NV Media Card. The latest User Menu A parameter set in
the drive is therefore always backed up on the NV Media Card.
Parameter Cloning Modes
(
N01
) should be set = Auto (3) and the drive reset which will immediately save the complete parameter set from the drive
to the NV Media Card, except parameters with the NC coding bit set. Once the whole parameter set is stored, only the individual modified User Menu
A parameter settings are updated.
Advanced parameter changes are only saved to the NV Media Card when Pr
mm00
is set to 'Save Parameters' or a 1000 and the drive reset.
If the data block already contains information it is automatically overwritten.
If the NV Media Card is removed when
Parameter Cloning Modes
(
N01
) is set to Auto (3)
Parameter Cloning Modes
(
N01
) is then automatically set to
None (0).
When a new NV Media Card is installed
Parameter Cloning Modes
(
N01
) must be set back to Auto (3) by the user and the drive reset so the complete
parameter set is rewritten to the new NV Media Card if auto mode is still required.
When
Parameter Cloning Modes
(
N01
) is set to Auto (3) and the parameters in the drive are saved, the NV Media Card is also updated, and therefore
the NV Media Card becomes a copy of the drives stored configuration.
At power up, if
Parameter Cloning Modes
(
N01
) is set to Auto (3), the drive will save the complete parameter set to the NV Media Card. The drive will
display 'Card Write' during this operation. This is done to ensure that if a user puts a new NV Media Card in during power down the new NV Media
Card will have the correct data.
