Reset to factory default values and adjust offsets
In order to start from a predefined set of parameter values, it is highly recommended that the "Restore to
default" function be executed before a complete new start-up operation is begun.
NOTE
When the "Restore to default" function is activated, all parameters set for a specific installation
are overwritten (deleted). If the old settings are to be retained they should be recorded before
the default procedure is executed. The old settings can be read out and stored in a file using a
PC and either the Quick Start or DriveMonitor PC program.
"Restore to default" must be followed by a completely new start-up operation since none of the
application related parameters are set.
Execution of the default function:
1. Set parameter P051 = 21
2. When the "P" key is pressed the parameter values are reset to the factory value.
The parameter values are stored in non-volatile storage (EEPROM) so that they will still be available
when the converter is switched off. This operation takes at least 5 s (but may also last several minutes).
The number of the parameter currently being processed is displayed on the PMU during the process.
The electronics power supply must remain powered up while this operation is in progress.
3. Field offset adjustments
Parameter P825.ii is automatically set (takes approx. 10 s) to provide proper calibration of the field
converter rated current. The offset adjustment can also be activated as an individual function by means
of parameter P051 = 22.
