ACH550-UH User's Manual
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.
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 (ACS/industrial or ACH/HVAC) and the same model (all ACH550).
• 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
ACH550. In order to use the timer functions of the ACH550, the internal clock has to
be set first. Date is used to determine weekdays and is visible in Fault logs.
