7.4.1 Overview of how to replace an inverter
Permissible replacement
You must replace the inverter if it continually malfunctions.
In the following cases you will need to replace the inverter:
Replacement:
● Same power rating
● Same firmware version
Replacement:
● Same power rating
● Higher firmware version
(e.g. replace FW V4.2 by
FW V4.3)
Replacement:
● Same frame size
● Higher power rating
● Same firmware version
Replacement:
● Same frame size
● Higher power rating
● Higher firmware version
(e.g. replace FW V4.2 by

Inverter and motor must match one another (ratio between
the motor and inverter rated power > 1/4)
After you have carried out the replacement, you must restore the inverter's settings.
WARNING
Risk of injury due to uncontrolled drive motion
Replacing inverters of different types can result in uncontrolled motion of the drive.
● In all cases that are not permitted according to the table above, recommission the drive
after replacing an inverter.
Special issue relating to communication via PROFINET: Device replacement without removable data
storage medium
The inverter supports the PROFINET functionality, replacing the device without data storage
medium.
Precondition
The topology of the PROFINET IO system with the IO device involved is configured in your
higher-level control system.
