9 NV Media Card Operation
9.1 Introduction
The Non-Volatile Media Card feature enables simple configuration of
parameters, parameter back-up and drive copying using a
SMARTCARD or SD card in the future. The drive offers backward
compatibility for a Unidrive SP SMARTCARD.
The SMARTCARD can be used for:
•
Parameter copying between drives
•
Saving drive parameter sets
The NV Media Card (SMARTCARD) is located at the top of the module
under the drive display (if installed) on the left-hand side.
Ensure SMARTCARD is inserted with the contacts facing the left-hand
side of the drive.
The drive only communicates with the NV Media Card when
commanded to read or write, meaning the card may be "hot swapped".

9.2 SMARTCARD support
The SMARTCARD can be used to store one drive parameter set from
the Unidrive M in data block 001 on the SMARTCARD.
The Unidrive M is compatible with a Unidrive SP SMARTCARD and is
able to read and translate the Unidrive SP parameter set into a
compatible parameter set for Unidrive M. This is only possible if the
Unidrive SP parameter set was transferred to the SMARTCARD using
the difference from defaults transfer method (i.e. 4yyy transfer). The
Unidrive M is not able to read any other type of Unidrive SP data block
on the card. Although it is possible to transfer difference from default
data blocks from a Unidrive SP into the Unidrive M, the following should
be noted:
1. If a parameter from the source drive does not exist in the target drive
then no data is transferred for that parameter.
2. If the data for the parameter in the target drive is out of range then
the data is limited to the range of the target parameter.
3. If the target drive has a different rating to the source drive then the
normal rules for this type of transfer apply.
Figure 9-2 Basic SMARTCARD operation
The whole card may be protected from writing or erasing by setting the
read-only flag as detailed section 9.3.9
clearing the SMARTCARD read only flag
The card should not be removed during data transfer, as the drive will
produce a trip. If this occurs then either the transfer should be
reattempted or in the case of a card to drive transfer, default parameters
should be loaded.
Beware of possible live terminals when installing the NV
Media Card.
