Abstract: A drive unit having a transport element has at least one entrainer engaging into a drive groove of a barrel cam, an electrical drive device, and a base control device that is adapted to receive control signals for the operation of the drive unit from a user interface programmable by an operator and to output a drive signal to the drive device in dependence on a received control signal. The drive device is adapted to drive the barrel cam to make a rotational movement and thus to drive the transport element in response to the drive signal. The base control device is further adapted to selectively operate the drive device in a full operation mode or, if no control signal is received after the output of a drive signal and after the elapse of a cycle time duration of the drive unit, to set it into a standby operation mode in which an electrical supply of the drive device is interrupted.

Abstract: The present invention relates to a method for operating a pivot drive, in particular a rotary indexing unit (10), having a rotating plate (12) which can be driven by a motor to execute a rotary movement about a rotation axis (R). A sensor (24, 24?) is provided, which provides sensor data, in particular angle data, is connected to a control device (26) and serves to monitor a rotary movement of the motor (22), the rotating plate (12) and/or a rotating component of a drive train which is arranged between the motor and the rotating plate. The sensor data is compared with predefined setpoint data, which is stored in the control device (26), in order to adjust at least one parameter which characterizes or influences the rotary movement if there is a deviation between the sensor data and the setpoint data, in order to minimize the ascertained deviation.
