Abstract: A drive system drives a switch. The drive system includes: a drive shaft connecting the drive system to the switch; a motor configured to drive the drive shaft; a feedback system; and a controller. The feedback system is configured to: determine at least one value for a position of the drive shaft; and generate a feedback signal based on the at least one value. The controller acts on an operation of the motor depending on the feedback signal.

Abstract: A switch assembly includes a switch and a servo drive system. The drive system includes: a drive shaft connecting the drive system to the switch; a motor driving the switch; a power section supplying power to the motor; a feedback system; and a programmable safety controller. The feedback system determines at least two values for an absolute position of the drive shaft; and generates a feedback signal on the basis of the values. The controller controls the power section depending on at least one desired value; influences an operation of the motor depending on the feedback signal; and identifies the presence of at least one safety-relevant event, and based thereon, transmits a control signal to the power section. The power section is initiates/carries-out at a safety measure depending on the control signal.

Abstract: A method carries out a switchover of a switch for at least one item of equipment. The method includes receiving, by a controller, a switching signal; selecting the at least one switch for switchover the controller on the basis of the switching signal; checking a locking condition for the selected switch on the basis of at least one parameter; and carrying out the switchover by the at least one selected switch by a motor of the switch upon determining that the corresponding locking condition is met.

Abstract: A switch assembly includes a switch; and a drive system for the switch. The drive system includes: a drive shaft connecting the drive system to the switch; a motor configured to drive the drive shaft; and a feedback system, which is configured to determine at least two values for a position of the drive shaft; and to generate a feedback signal on the basis of the at least two values; and a control device which is configured to influence an operation of the motor depending on the feedback signal.

Abstract: A switch assembly has a switch; and a servo drive system for the switch. The servo drive system includes: a motor configured to drive the switch; a power section configured to supply power to the motor; and a control unit configured to control the power section depending on at least one desired value. The control unit is configured to identify the presence of at least one safety-relevant event and, in the case of the safety-relevant event, to transmit at least one control signal to the power section. The power section is configured to initiate or carry out at least one safety measure depending on the control signal.

Abstract: A method for carrying out a switchover of a switch from a current switching position to a target switching position by means of a drive system. The method includes receiving, by the drive system, a switching signal from a control device, determining, via a feedback signal of a feedback system, at least one value for a first position of a drive shaft of the drive system, determining, by the control device, a value for a second position of the drive shaft on the basis of the target switching position, to be moved to, of the switch, and ascertaining, by the control device, a difference between the value for the first position and the value for the second position of the drive shaft. The control device, depending on the feedback signal, acts on a motor until the value for the second position of the drive shaft is reached.
