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 option modules fitted

If the categories of the option modules fitted 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 option modules fitted 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 option modules

can apply different limits on the speed references, therefore these can be affected when parameters are transferred between drives with different

position feedback option modules fitted where the option 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.
