WARNING
Unexpected machine movements caused by incorrect/inappropriate inverter settings
Replacing inverters of different types can result in incomplete or incorrect/inappropriate
inverter settings. As a consequence, unexpected machine motion, e.g. speed oscillation,
overspeed or incorrect direction of rotation. Unexpected machine motion can result in death,
injury or material damage.
● 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.
Requirement
The topology of the PROFINET IO system with the IO device involved is configured in your
higher-level control system.
