Corrective maintenance
9.2 Replacing inverter components
Unexpected machine motion caused by inappropriate/incorrect inverter settings
Replacing inverters of different types can result in incomplete or inappropriate/incorrect
inverter settings. As a consequence, machines can unexpectedly move, e.g. speed
oscillation, overspeed or incorrect direction of rotation. Unexpected machine motion can
result in death, injury and/or material damage.
• In all cases that are not permitted according to the table above, recommission the drive
Device replacement without removable storage medium - only for communication via PROFINET
If you have created a topology in your control, you can use environment detection to replace
a defective converter with a new device of the same type and with the same software
release. Recommissioning is not required in this case.
You can either load the converter settings into the converter using the memory card or – if
you are using a SIMATIC S7 controller with DriveES – using DriveES.
Additional information about replacing devices without removable storage medium can be
