parameter set for Unidrive M. This is only possible if the Unidrive SP parameter set was transferred to the smart card using the difference from defaults

transfer method (i.e. 4yyy transfer). The Unidrive M 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, 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.

SD Card File system layout

The folder <MCDF/> ("Motor Control Data Files") must be present on a FAT-formatted SD card. Other folders can be added. This folder structure is

created when a Card Error trip is reset. Initially the folders are empty apart from the <000> file.

Writing to an SD card the drive will place files in a <MCDF/> folder in the card root. There are two possible cases here; these are illustrated in the

example folder listing below:

1. Saving an individual item (e.g. drive parameters or a user program) will generate a numbered file in the root of this folder; the number is that

specified in the triggering command, and this number must be specified in the command used to restore the item from the file. This is equivalent

functionality to that provided on a smart card. When saving a parameter file, in addition to the drive parameters, the drive will also read the

option parameters from each of the installed options, and include those that have changed in the parameter file.

2. Cloned drive data will be stored in a numbered <drivexxx> subfolder; this structure groups together all data from a single drive and also allows

storage of option-specific data (e.g. from an internal parameter database or some fieldbus specific objects which are not stored in parameters).

Changing the drive mode

If the source drive mode is different from the target drive mode then the mode will be changed to the source drive mode before the parameters are

transferred. If the required drive mode is outside the allowed range for the target then a Card Drive Mode trip is initiated and no data is transferred.

Different voltage ratings

If the voltage rating of the source and target drives is different then all parameters except those that are rating dependent are transferred to the target

drive. The rating dependent parameters are left at their default values. After the parameters have been transferred and saved to non-volatile memory a

Card Rating trip is given as a warning. The table below gives a list of the rating dependent parameters.
