Motor protection
•
Version with plug:
-
Never disconnect the plug when energized. The plug could be destroyed.
-
Switch off the voltage supply or disable the inverter prior to disconnecting the plug.
•
Installed thermal detectors are no full protection for the machine.
-
Limit the maximum current if necessary. Parameterize the inverter so that it will be
switched off after several seconds of operation with I > I
rated
especially if there is a
danger of blocking.
-
The integrated overload protection does not prevent overloading under all conditions.
•
The fuses are no motor protection.
-
Use a current-dependent motor protection switch.
-
Use the built-in thermal detectors.
•
Excessively high torques cause a fracture of the motor shaft.
-
Do not exceed the maximum torques according to the technical data on the
nameplate.
•
Lateral forces on the motor shaft are possible.
