Par Backup Mode

The Assistant Control Panel can store a full set of drive parameters.
The Par Backup mode has these functions:
• Upload to Panel – Copies all parameters from the drive to the Control Panel.
This includes user sets of parameters (if defined) and internal parameters such as
those created by the Motor Id Run. The Control Panel memory is non-volatile and
does not depend on the panel's battery.
• Download Full Set – Restores the full parameter set from the Control Panel to
the drive. Use this option to restore a drive, or to configure identical drives. This
download does not include user sets of parameters.
Note! Download Full Set writes all parameters to the drive, including motor
parameters. Only use this function to restore a drive, or to transfer parameters to
systems that are identical to the original system.
• Download Application – Copies a partial parameter set from the Control Panel
to a drive. The partial set does not include internal motor parameters, parameters
9905...9909, 1605, 1607, 5201, nor any Group 51 and 53 parameters. Use this
option to transfer parameters to systems that use similar configurations – the
drive and motor sizes do not need to be the same.
• Download User Set 1 - Copies
parameter 9902
• Download User Set 2 - Copies
drive.
The general procedure for parameter backup operations is:
1. Select PAR BACKUP in the Main Menu.
2. Press UP/DOWN to step to the desired option.
3. Press ENTER.
The parameter set is transferred as directed. During the transfer, the display shows
the transfer status as a percent of completion.
4. Press EXIT to step back to the Output mode.

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 8 kHz.
