below. In addition to data transfers a compare function is provided.
If 8yyy is entered in Pr
x.00
and the drive is reset data block yyy on the SMARTCARD is compared with the data in the drive. If the compare is
successful Pr
x.00
is simply set to 0. If the compare fails a trip is initiated and parameter x.00 is not cleared. This function can be used with all data
block types except the option type (18) and Opt.prg (19) type of data block.
Parameter

data
block
This type of data block is created when 3xxx in
Pr
x.00
, the copying parameter (Pr
11.42
=
{SE09,
0.30}
) or auto/boot mode is used to initiate the
transfer. The data block (referred to as a parameter file) contains the complete data from all user save (US) parameters except those with the NC
coding bit set. Parameter RAM is used as the source of this information. Power-down save (PS) are not saved to the SMARTCARD. When the data is
transferred back to a drive, it is transferred to the drive RAM and then the drive EEPROM. A parameter save is not required to retain the data after
power-down. Before the data is taken from the card, defaults are loaded in the destination drive using the same default code as was last used in the
source drive.

type
data
block
This type of data block is created when 4xxx in Pr
x.00
is used to initiate the transfer. The data held in the data block has changed between different
software versions as follows:
Parameters with the following attributes: NC=0 (clonable) and US=1 (user save), and menu 20 parameters except Pr
20.00
if they are different from
their default value. If a parameter is user save (US), but has no default (ND) it is saved on the card whatever its value.
The data density is not as high as a parameter file type data block, but in most cases the number of differences from default is small and the data
blocks are therefore smaller. This method can be used, for example, for creating drive macros. Parameter RAM is used as the source of this
information.
When the data is transferred back to a drive, using 6yyy in Pr
x.00
, it is transferred to the drive RAM and then to the drive EEPROM. A parameter
save is not required to retain the data after power-down.
Onboard
Application

user

data
blocks
This type of data block is created when 5xxx in Pr
x.00
is used to initiate the transfer. The Onboard Application Lite user program from a drive may be
transferred to/from internal flash memory from/to a SMARTCARD. If the user program is transferred from a drive with no program loaded the block is
still created on the card, but contains no data. If this is then transferred to a drive the drive will then have no user program.
Option
type
data
block
This type of block is created by an application module, and contains user defined data.
When transferring data between drives the following should be noted:
Parameter
transfer
failure
When parameter or default difference data is transferred to the drive the parameters are automatically saved to drive EEPROM. If the transfer from
the card fails for any reason the drive produces the appropriate trip. If the failure occurs after the transfer has begun, it is possible that some, but not
all the parameters will have been updated with the card data. However, if the transfer fails the parameters are not saved to drive EEPROM, therefore
only the RAM values will be incorrect. If the drive is powered down and then powered up again the original drive parameters will be restored.
