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.
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.
