Abstract: A control system for an electric motor in a manufacturing environment, the control system including: a safety relay; and a power reduction circuit, wherein, when the safety relay is triggered, the power reduction circuit automatically limits the power supplied to the electric motor from a main power source such that the electric motor operates in a predetermined safe mode. A method for controlling an electric motor in a manufacturing system, the electric motor having a main power supply, the method including: monitoring the manufacturing system associated with the electric motor for a change in condition; on detecting a change in condition: limiting a power supplied to the electric motor, via a power reduction circuit, such that the electric motor operates in a predetermined safe mode. The power reduction circuit includes a reduced power supply and a means of dropping the power supplied to the electric motor quickly.
