Power Module and motor must be
adapted to one another (ratio of mo‐
tor and Power Module rated power
> 1/4)
After replacing the Control Unit, you must restore the inver‐
ter's settings.
WARNING
Risk of injury due to uncontrolled drive motion
Replacing inverters with different firmware 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.
