• Blockage detection 

General 

Blockage detection protects the component parts involved against damage caused by a load that is too strong and enables the setting of end points during normalization.

Blockage detection 

A blockage is detected if during the actuation of an electric motor:

• The RPM signal of the electric motor is absent
• A force defined in the system is exceeded

The power consumption of the electric motor serves as a reference for the force.

Once a blockage is detected, actuation of the electric motor is immediately stopped.

Depending on the system, the actuation of the electric motor is reversed for a certain time or a certain way.
