7.3 Commissioning and optimization of the drive application

After the motor and converter combination is commissioned by quick commissioning,

parameters must be adapted and set to suit the requirements of the specific application.

Note

According to the factory setting, parameter changes are saved in the volatile memory (RAM)

of the converter. One of the following options can be used for saving the changes to

EEPROM:

• Set P0014 = 1: all changes are then saved immediately to EEPROM

• Trigger transfer from RAM to EEPROM via P0971 = 1

or via the STARTER button

The duration of the data transfer depends on the number of parameters changed. In some

cases it can take up to 3 minutes.

When using STARTER, the transfer is indicated by a progress bar. A dialog field announces

when transfer is successful.

The

List Manual

contains detailed parameter descriptions.
