WARNING
Unexpected machine motion caused by inappropriate/incorrect converter settings
Missing or incorrect converter settings can lead to unexpected operating states or machine
movements, e.g. a non-functioning EMERGENCY STOP or an incorrect direction of rotation. As
a consequence, machine components or devices can become damaged or death or bodily
injury may result.
• Back up the settings of the converter to be replaced by uploading them to an external
storage medium, e.g. a memory card.
• Transfer the settings of the converter to be replaced by downloading them to the new
converter.
• If you do not have a backup of the converter settings, commission the new converter as
completely new converter.
• Check that the new converter works properly.
Procedure
1. Disconnect the line voltage to the converter.
WARNING
Electric shock as a result of a residual charge in power components
After the power supply has been switched o󹪜, it takes up to 5 min. until the capacitors in the
converter have discharged so that the residual charge is at a non-hazardous level.
• Check the voltage at the converter connections, before removing the connection cables.
2. Remove the connecting cables of the converter.
3. Remove the defective converter.
4. Install the new converter.
5. Connect all of the cables to the converter.
NOTICE
Damage caused by interchanging the motor cables
The direction in which the motor rotates switches if you exchange the two phases of the
motor line. An incorrect direction of rotation can lead to damage in the machine or system.
• Connect the 3 phases of the motor lines in the correct sequence.
6. Switch on the line voltage of the converter.
7. Set the new converter to suit the application:
– If the settings of the replaced converter are backed up on an external storage medium,
transfer the settings via a download.

– If there is no data backup of the replaced converter, commission the converter as new
converter.
