Abstract
A multiple drive for a heavy load application includes a plurality of drive trains which are activated such that individual ones of the plurality of drive trains are successively activated automatically during startup of the heavy load application as part of a predefined activation strategy according to a predefined activation scheme and an activation sequence defined therein. In the event of a repeated start of the heavy-load application, a different activation scheme can be used for the activation.

A multiple drive for a heavy load application, comprising a plurality of drive trains which are activated such that individual ones of the plurality of drive trains are successively activated automatically during startup of the heavy load application as part of a predefined activation strategy according to a predefined activation scheme and an activation sequence defined therein, wherein a different activation scheme is used when the startup of the heavy load application is repeated.
A method for operating a multiple drive for a heavy load application, comprising:
- automatically activating individual drive trains successively from a plurality of drive trains of the multiple drive during a startup of the heavy load application as part of a predefined activation strategy according to a predefined activation scheme and an activation sequence defined therein;
- and
- using a different activation scheme when the startup of the heavy load application is repeated.
A computer program comprising program code which, when executed by a control device for controlling a multiple drive for a heavy load application, causes the control device to perform the steps of:
- automatically activating individual drive trains successively from a plurality of drive trains of the multiple drive during a startup of the heavy load application as part of a predefined activation strategy according to a predefined activation scheme and an activation sequence defined therein;
- and
- using a different activation scheme when the startup of the heavy load application is repeated.
A control device for controlling a multiple drive for a heavy load application, comprising:
- a processing unit;
- a memory;
- and
- a computer program embodied as a control program which, when loaded into the memory and executed by the processing unit during operation of the control device causes the processing unit to perform the steps of:
- automatically activating individual drive trains successively from a plurality of drive trains of the multiple drive during a startup of the heavy load application as part of a predefined activation strategy according to a predefined activation scheme and an activation sequence defined therein;
- and
- using a different activation scheme when the startup of the heavy load application is repeated.
A vertical mill, comprising:
- a multiple drive for a heavy load application, said multiple drive comprising a plurality of drive trains which are activated such that individual ones of the plurality of drive trains are successively activated automatically during startup of the heavy load application as part of a predefined activation strategy according to a predefined activation scheme and an activation sequence defined therein, wherein a different activation scheme is used when the startup of the heavy load application is repeated;
- and
- a control device for controlling the multiple drive, said control device comprising a processing unit, a memory, and a computer program embodied as a control program in a non-transitory computer readable medium, wherein the computer program, when loaded into the memory and executed by the processing unit during operation of the control device causes the processing unit to perform the steps of automatically activating individual drive trains successively from a plurality of drive trains of the multiple drive during a startup of the heavy load application as part of a predefined activation strategy according to a predefined activation scheme and an activation sequence defined therein, and using a different activation scheme when the startup of the heavy load application is repeated.
