Abstract
A drive controller comprises an evaluation unit to receive and evaluate a first item of feedback information from a motor connected to the drive controller, a control-signal block connected to secure inputs of the drive controller to receive condition control signals and to provide the condition control signals as input signals, a drive-signal block connected to the evaluation unit to calculate a first speed and/or a first position on the basis of the first item of feedback information on at least a first channel and to provide a first speed signal and/or a first position signal, a programmable logic unit connected to the control-signal block and the drive-signal block to realize the safety functions and the speed signal and/or the position signal to provide switch-off signals, and an output unit connected to the logic unit and to secure outputs of the drive controller to output switch-off signals on safety-switch-off paths.
