Abstract
A sewing machine (1) with an overload clutch in the form of a friction clutch in the region of the handwheel (44), with a positioning motor (57), including a motor part (56) and a control part (55), and with a position transmitter (51) connected to the arm shaft (5). In the event of a blockage of the arm shaft (5), the control part (56) causes the positioning motor (57) to stop immediately and a fault warning to be output on an indicator panel (68) of the control apparatus (66). After the fault has been eliminated and the power supply has subsequently switched off and switched on again, the sewing machine (1) is ready for operation again.
