4.13.2 NV Media Card support
The NV Media Card can be used to store drive parameters and / or PLC programs set from the
Unidrive M/HS in data blocks 001 to 499.
The Unidrive M/HS 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/HS. 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/HS 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/HS, 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 4-6 Basic NV Media Card operation
The whole card may be protected from writing or erasing by setting the read-only flag, refer to the
Drive User Guide for further information.
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.
