Reading a parameter set from the NV Media Card (Pr 11.042
= Read (1))
Setting Pr 11.042 to Read (1) and resetting the drive will transfer the
parameters from the card into the drive parameter set and the drive
EEPROM, i.e. this is equivalent to writing 6001 to Pr mm.000.
All NV Media Card trips apply. 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.
9.3.3 Auto saving parameter changes (Pr 11.042 =
Auto (3))
This setting causes the drive to automatically save any changes made to
menu 0 parameters on the drive to the NV Media Card. The latest menu
0 parameter set in the drive is therefore always backed up on the NV
Media Card. Changing Pr 11.042 to Auto (3) and resetting the drive will
immediately save the complete parameter set from the drive to the card,
i.e. all parameters except parameters with the NC coding bit set. Once
the whole parameter set is stored only the individual modified menu 0
parameter setting is updated.
Advanced parameter changes are only saved to the NV Media Card
when Pr mm.000 is set to 'Save Parameters' or a 1000 and the drive
reset.
All NV Media Card trips apply, except 'Card Change'. If the data block
already contains information it is automatically overwritten.
If the card is removed when Pr 11.042 is set to 3 Pr 11.042 is then
automatically set to None (0).
When a new NV Media Card is installed Pr 11.042 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 Pr 11.042 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 Pr 11.042 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.
NOTE
When Pr 11.042 is set to Auto (3) the setting of Pr 11.042 itself is saved
to the drive EEPROM but not the NV Media Card.
9.3.4 Booting up from the NV Media Card on every
power up (Pr 11.042 = Boot (4))
When Pr 11.042 is set to Boot (4) the drive operates the same as Auto
mode except when the drive is powered-up. The parameters on the NV
Media Card will be automatically transferred to the drive at power up if
the following are true:
• A card is inserted in the drive
• Parameter data block 1 exists on the card
• The data in block 1 is type 1 to 4 (as defined in Pr 11.038)
• Pr 11.042 on the card set to Boot (4)
The drive will display 'Booting Parameters during this operation. If the
drive mode is different from that on the card, the drive gives a 'Card
Drive Mode' trip and the data is not transferred.
If 'Boot' mode is stored on the copying NV Media Card this makes the
copying NV Media Card the master device. This provides a very fast and
efficient way of re-programming a number of drives.
NOTE
'Boot' mode is saved to the card, but when the card is read, the value of
Pr 11.042 is not transferred to the drive.
9.3.5 Booting up from the NV Media Card on every
power up (Pr mm.000 = 2001)
It is possible to create a bootable parameter data block by setting
Pr mm.000 to 2001 and initiating a drive reset. This data block is created
in one operation and is not updated when further parameter changes are
made.

Setting Pr mm.000 to 2001 will overwrite the data block 1 on the card if it
already exists.
9.3.6 8yyy - Comparing the drive full parameter set
with the NV Media Card values
Setting 8yyy in Pr mm.000, will compare the NV Media Card file with the
data in the drive. If the compare is successful Pr mm.000 is simply set to
0. If the compare fails a 'Card Compare' trip is initiated.
9.3.7 7yyy / 9999 - Erasing data from the NV Media
Card values
Data can be erased from the NV Media Card either one block at a time
or all blocks in one go.
• Setting 7yyy in Pr mm.000 will erase NV Media Card data block yyy
• Setting 9999 in Pr mm.000 will erase all the data blocks on a
SMARTCARD, but not on an SD Card.
9.3.8 9666 / 9555 - Setting and clearing the NV Media
Card warning suppression flag
If the option modules installed to the source and destination drive are
different or are in different slots the drive will produce a 'Card Option' trip.
If the data is being transferred to a drive of a different voltage or current
rating a 'Card Rating' trip will occur. It is possible to suppress these trips
by setting the warning suppression flag. If this flag is set the drive will not
trip if the option module(s) or drive ratings are different between the
source and destination drives. The options module or rating dependent
parameters will not be transferred.
• Setting 9666 in Pr mm.000 will set the warning suppression flag
• Setting 9555 in Pr mm.000 will clear the warning suppression flag
9.3.9 9888 / 9777 - Setting and clearing the NV Media
Card read only flag
The NV Media Card may be protected from writing or erasing by setting
the read only flag. If an attempt is made to write or erase a data block
when the read only flag is set, a 'Card Read Only' trip is initiated. When
the read only flag is set only codes 6yyy or 9777 are effective.
• Setting 9888 in Pr mm.000 will set the read only flag
• Setting 9777 in Pr mm.000 will clear the read only flag

Data block header information

Each data block stored on a NV Media Card has header information
detailing the following:
• NV Media Card File Number (11.037)
• NV Media Card File Type (11.038)
• NV Media Card File Version (11.039)
• NV Media Card File Checksum (11.040)
The header information for each data block which has been used can be
viewed in Pr 11.038 to Pr 11.040 by increasing or decreasing the data
block number set in Pr 11.037. If there is no data on the card Pr 11.037
can only have a value of 0.
