The SMARTCARD has 999 individual data block locations. Each
individual location from 1 to 499 can be used to store data until the
capacity of the SMARTCARD is used. With software V01.07.00 and later
the drive can support SMARTCARDs with a capacity of between 4kB
and 512kB. With software V01.06.02 and earlier the drive can support
SMARTCARDs with a capacity of 4kB.
The data block locations of the SMARTCARD are arranged to have the
following usage:
Table 9-1 SMARTCARD data blocks
Data Block

Read / Write
500 to 999
Read Only
'Differences from default' parameter sets will be much smaller than
whole parameter sets and thus take up a lot less memory as most
applications only require a few parameters to be changed from the
default setting.
The whole card may be protected from writing or erasing by setting the
read-only flag as detailed section 9.2.9 9888 / 9777 - Setting and
clearing the SMARTCARD read only flag on page 153.
Data transfer to or from the SMARTCARD is indicated by one the
following:
•
SM-Keypad/SP0 Keypad: The decimal point after the fourth digit in
the upper display will flash.
•
SM-Keypad Plus: The symbol 'CC' will appear in the lower left hand
corner of the display
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.

Transferring data
Data transfer, erasing and protecting the information is performed by
entering a code in Pr xx.00 and then resetting the drive as shown in
Table 9-2.

9.2.1
Writing to the SMARTCARD
3yyy - Transfer data to the SMARTCARD
The data block contains the complete parameter data from the drive, i.e.
all user save (US) parameters except parameters with the NC coding bit
set. Power-down save (PS) parameters are not transferred to the
SMARTCARD.
With software V01.06.02 and earlier, a save must have been performed
on the drive to transfer the parameters from the drive RAM to the
EEPROM before the transfer to the SMARTCARD is carried out.
