US 9,156,118 B2 · Method of operating a pivot drive

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.

Dependent claims

A method of operating a pivot drive having a turntable which can be driven by a motor to make a rotational movement about an axis of rotation, wherein at least one sensor is provided which delivers sensor data and which is connected to a control device for monitoring a rotational movement of the motor of the turntable and/or of a rotating component of a drive train arranged between the motor and the turntable,

wherein the sensor data are compared with predefined DESIRED data which are stored in the control device to adapt at least one parameter characterizing or influencing the rotational movement on a deviation of the sensor data from the DESIRED data to minimize the determined deviation,
wherein the sensor data are determined during a measuring cycle which includes a predefined time period or a predefined amount of the rotational movement and the determined sensor data are compared with the corresponding DESIRED data to determine an ACTUAL/DESIRED error which is specific to the measuring cycle and which is used as the basis for the adaptation of the at least one parameter,
wherein individual values of the sensor data are compared with corresponding individual values of the DESIRED data during the measuring cycle in order continuously to update an ACTUAL/DESIRED error and to compare this error with a threshold value.

wherein the sensor data are compared with predefined DESIRED data which are stored in the control device to adapt at least one parameter characterizing or influencing the rotational movement on a deviation of the sensor data from the DESIRED data to minimize the determined deviation,
wherein the sensor data are determined during a measuring cycle which includes a predefined time period or a predefined amount of the rotational movement and the determined sensor data are compared with the corresponding DESIRED data to determine an ACTUAL/DESIRED error which is specific to the measuring cycle and which is used as the basis for the adaptation of the at least one parameter,
wherein a teaching cycle including a predefined number of measuring cycles is completed for a teaching process for determining a value of the at least one parameter suitable for a standard operation or a function of the at least one parameter suitable for a standard operation, with the at least one parameter or its function being adapted iteratively in the course of the teaching cycle to minimize the deviation.
