Abstract
The present invention relates to a method for synchronously controlling a first motor and a second motor, wherein the first motor is controlled by a first drive unit, the second motor is controlled by a second drive unit, wherein the first motor and the second motor work together to drive the same axis and/or to move the same load, wherein the drive units each perform a closed loop control for driving the respective motor, wherein the closed loop control of each of the drive units is based on the same control loop data set.
Claims20
A method for synchronously controlling a first motor and a second motor,
- wherein the first motor is controlled by a first drive unit, the second motor is controlled by a second drive unit,
- wherein the first motor and the second motor work together to drive the same axis and/or to move the same load,
- wherein the drive units each perform a closed loop control for driving the respective motor, wherein the closed loop control of each of the drive units is based on the same control loop data set.
A motor system comprising a first motor and a second motor, a first drive unit and a second drive unit as well as a driven axis or a moved load,
- wherein the first motor is controlled by the first drive unit, the second motor is controlled by the second drive unit,
- wherein the first motor and the second motor work together to drive the axis and/or to move the load,
- wherein the drive units each are configured to perform a closed loop control for driving the respective motor, wherein the closed loop control of each of the drive units is based on the same control loop data set.
A multicarrier system comprising a plurality of linear motors, the linear motors are arranged along a track, wherein a plurality of carriers are arranged at the track and are independently movable along the track by the linear motors,
- wherein at least two of the linear motors are part of a motor system comprising a first motor and a second motor, a first drive unit and a second drive unit as well as a driven axis or a moved load,
- wherein the first motor is controlled by the first drive unit, the second motor is controlled by the second drive unit,
- wherein the first motor and the second motor work together to drive the axis and/or to move the load,
- wherein the drive units each are configured to perform a closed loop control for driving the respective motor, wherein the closed loop control of each of the drive units is based on the same control loop data set.
