Handling inexact downloads
In some situations, an exact copy of the download is not appropriate for the target
drive. Some examples:
• A download to an old drive specifies parameters/values that are not available on
the old drive.
• A download (from an old drive) to a new drive does not have definitions for the
new parameters – parameters that did not originally exist.
• A download can include an illegal value for the target drive, e.g. a backup from a
small drive can have a switching frequency of 12 kHz whereas a big drive can
only handle 8k Hz.
As a default, the control panel handles these situations by:
• Discarding parameters/values not available on
the target drive.
• Using parameter default values when the
download provides no values or invalid values.
• Providing a Differences List – A listing of the
type and number of items that the target cannot
accept exactly as specified.
You can either accept the default edits by pressing
READY, or view and edit each item as follows:
1. Highlight an item type in the Differences List (left screen below) and press SEL to
see the details for the selected type (right screen below).

In the above-right "details" screen:
• The first item that requires editing is automatically highlighted and includes
details: In general, the first item listed in the details is the value defined by the
backup file. The second item listed is the "default edit."
• For tracking purposes, an asterisk initially appears by each item. As edits are
made, the asterisks disappear.
2. In the illustrated example, the backup specifies a switching frequency of 12 kHz, but
the target drive is limited to 8 kHz.
3. Press EDIT to edit the parameter. The display is the target drive's standard edit
screen for the selected parameter.
4. Highlight the desired value for the target drive.
5. Press SAVE to save setting.
