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 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 .
6 . Press EXIT to step back to the differences view and
continue for each remaining exception .
7 . When your editing is complete, press READY in the
Differences List and then select "Yes, save parameters ."

Download Failures
In some situations, the drive may be unable to accept a
download . In those cases, the control panel display is:
"Parameter download failed" plus one of the following causes:
• Set not found – You are attempting to download a data
set that was not defined in the backup. The remedy is to
manually define the set, or upload the set from a drive
that has the desired set definitions.
• Par lock – The remedy is to unlock the parameter set
(parameter 1602,
• Incompat drive/model – The remedy is to perform
backups only between drives of the same type and the
same model .
• Too many differences – The remedy is to manually define
a new set, or upload the set from a drive that more
closely resembles the target drive .
NOTE: If upload or download of parameters is aborted, the
partial parameter set is not implemented .
Clock Set Mode
The clock set mode is used for setting the time and date for
the internal clock of the ACS320 . In order to use the timer
functions of the ACS320, the internal clock has to be set first.
Date is used to determine weekdays and is visible in Fault
logs .
