Switching device, electrical drive and method for setting up a switching device

A switching device for switching an electric motor, the switching device comprising:

• a control unit which is configured to provide a first switching signal for the electric motor;
• a memory which is connected communicatively to the control unit and is configured to store at least one limit position;
• and
• a position sensor which can be connected to an element driven by the electric motor and is connected communicatively to the control unit and is configured to provide the control unit with an electrical position signal which indicates a measured position;
• wherein the control unit is connected communicatively to a wireless communicator and is configured to store the measured position in the memory as said at least one limit position based on the position signal in response to a first instruction received by the wireless communicator;
• and
• wherein the control unit is configured to:
• provide the first switching signal based on a comparison between the at least one limit position stored in the memory and a position signal measured by the position sensor;
• receive a setup message via the wireless communicator, wherein the setup message comprises a value of at least one desired limit position;
• and
• store the value of the at least one desired limit position in the memory as said at least one limit position in response to receiving the setup message.

A method for setting up at least two switching devices, the method comprising:

• providing a first electric motor connected to a first switching device of the at least two switching devices, the first switching device comprising:
• a control unit which is configured to provide a first switching signal for the first electric motor;
• a memory which is connected communicatively to the control unit and is configured to store at least one limit position;
• and
• a position sensor which can be connected to an element driven by the first electric motor and is connected communicatively to the control unit and is configured to provide the control unit with an electrical position signal which indicates a measured position;
• wherein the control unit is connected communicatively to a wireless communicator and is configured to store the measured position in the memory as said at least one limit position based on the position signal in response to a first instruction received by the wireless communicator;
• wherein the control unit is configured to:
• provide the first switching signal based on a comparison between the at least one limit position stored in the memory and a position signal measured by the position sensor;
• receive a third instruction via the wireless communicator;
• and
• transmit a message comprising information about at least the at least one stored limit position in response to receiving the third instruction;
• providing a second electric motor connected to a second switching device of the at least two switching devices, the second switching device comprising:
• a control unit which is configured to provide a first switching signal for the second electric motor;
• a memory which is connected communicatively to the control unit and is configured to store at least one limit position;
• and
• a position sensor which can be connected to an element driven by the electric second motor and is connected communicatively to the control unit and is configured to provide the control unit with an electrical position signal which indicates a measured position;
• wherein the control unit is connected communicatively to a wireless communicator and is configured to store the measured position in the memory as said at least one limit position based on the position signal in response to a first instruction received by the wireless communicator;
• wherein the control unit of the second switching device is configured to:
• provide the first switching signal based on a comparison between the at least one limit position stored in the memory and a position signal measured by the position sensor;
• receive a setup message via the wireless communicator, wherein the setup message comprises information about at least one desired limit position;
• and
• store the desired limit position in the memory as said at least one limit position in response to receiving the setup message;
• wherein the first and the second electric motor are in a same position;
• the method further comprising:
• setting up the first switching device by:
• a) moving the driven element to a position that corresponds with a limit position which must be stored;
• and
• b) transmitting the first instruction via the wireless communicator or providing the second instruction via a user interface;
• retrieving the at least one stored limit position of the first switching device by transmitting the third instruction via the wireless communication means of the first switching device;
• and
• setting up the second switching device by transmitting, via the wireless communicator thereof, a setup message comprising information about the at least one requested limit position of the first switching device.
