Read-only
function
Data blocks with numbers from 1 to 499 can be created or erased by the user. Data block with numbers 500 and above are read-only and cannot be
created or erased by the user. The whole card may also be protected from writing or erasing by setting the read-only flag. If the card or a data block
on the card is read-only, then the operation to erase the whole card is disabled.
Different
voltage
ratings
If the voltage rating of the source and destination drive are different then the parameters are transferred with the exception of rating dependent
parameters (RA attribute set, see table below), which are left at their default values. In this case a C.rtg trip is given as a warning that this has
happened. It is possible to suppress this warning trip for any data transfer to the drive, including a boot transfer at power-up by setting the warning
suppression flag for the whole card.
Different
Solutions
Modules
installed
If the categories of the Solutions Modules installed to the source drive are different to the destination drive then the parameters are transferred with
the exception of the parameters in the menus of the modules that are different. These parameters are left at their default values. In this case a C.Optn
trip is given as a warning. It is possible to suppress this warning trip for any data transfer to the drive, including a boot transfer at power-up by setting
the warning suppression flag for the whole card.
Different
current/voltage
rating
with
a
parameter
file
type
data
block
If the current or voltage ratings of the source and destination drive are different and the parameters stored as a parameter file (not differences from
default) then rating dependant parameters are set to their defaults and a C.rtg trip is produced as described above where the voltage ratings are
different. It is possible to suppress this warning trip for any data transfer to the drive, including a boot transfer at power-up by setting the warning
suppression flag for the whole card.
Effects
of
variable
maximums
if
ratings
or
options
are
different
It should be noted that if ratings of the source and destination drives are different, or the Solutions Modules installed to the source and destination
drives are different, it is possible that some parameters with variable maximums may be limited and not have the same values as on the card. For
example the user current maximum scaling (Pr
4.24
) is rating dependent and could be set to its default value when it is transferred between drives of
different ratings, but this could also affect the torque reference (Pr
4.08
) as this uses Pr
4.24
as its maximum. Also different position feedback
Solutions Modules can apply different limits on the speed references, therefore these can be affected when parameters are transferred between
drives with different position feedback Solutions Modules installed where the Solutions Module is being used for the drive position feedback.
Product
identifier
The product identifier is written to the card when the whole card is erased.
If the identifier does not match the drive product and the card contains any data blocks a C.Prod trip is produced. Also if the following functions are
initiated a C.Acc trip is produced and the card or drive data is not affected: erase file, transfer data block from card to drive, or transfer data block from
drive to card. It is still possible to use Pr
11.37
to browse information about the whole card (i.e. Pr
11.37
= 1000 to 1003), but it is not possible to see
the data block information (i.e. Pr
11.37
< 1000). It is also possible to change the card header information (i.e. read-only flag and warning suppression
flag). This feature allows the read-only flag to be cleared so that a card can be erased to be used with the product that performs the card erase.
If the card does not contain any data blocks (i.e. an erased card) and the identifier does not match that of the drive then the drive will automatically
change the identifier on the card to match when it is first inserted.
