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