If required, limit the maximum current. Parameterise the inverter so that it will be switched o aer
seconds of operaon with I > I
rated
, especially if there is the danger of blocking.

The installed overload protecon does not prevent an overload under any condions.
•
The fuses are no motor protecon.
-
Use a current-dependent motor protecon switch.

Use the built-in thermal detectors.
•
Too high torques cause a fracon of the motor sha.
-
The maximum torques according to catalogue must not be exceeded.
