Abstract:
A control circuit configured to control an electromechanical brake is provided. The control circuit includes: a switching regulator configured to control a magnitude of voltage applied to a brake coil of the electromechanical brake; wherein said switching regulator includes at least one semiconductor switch, one diode, one capacitor and one inductor; the control circuit is configured such that, in operation, at least one signal from a process sub-system specifies the magnitude of the voltage for the brake coil; and at least one brake applying control signal from a safety sub-system can cause the brake coil voltage to be reduced to a level low enough to apply the brake by opening a switch and each brake applying control signal from the safety sub-system has a corresponding diagnostic feedback signal to the safety sub-system that indicates the state of the corresponding switch. A method and a system are disclosed.
