Abstract: A disconnect override circuit for a power conversion system includes a first input coupled to a user disconnect switch to receive a disconnect input signal, as well as a second input coupled to a motor drive or motor starter to receive a fault signal, and a third input adapted to receive an override signal. The disconnect override circuit has an output configured to provide a disconnect control output signal to control a user disconnect circuit according to the disconnect input signal, the fault signal and the override signal, the output signal having a first state to cause the user disconnect circuit to allow power transfer from the AC input to the motor drive or motor starter, and a second state to cause the user disconnect circuit to prevent power transfer from the AC input to the motor drive or motor starter.

Abstract: A method may include receiving, via a processor, a request to enable movement of a rotor. The method may involve sending a first signal to a mechanical relay system in response to receiving the request, such that the second signal may cause a mechanical relay to close. The mechanical relay system is configured to couple a first conductor to an EM brake. The method may also include sending a second signal to a solid-state relay system after sending the first signal to the mechanical relay system, such that the second signal may cause a solid-state relay to close. The solid-state relay system may couple a second conductor to the EM brake, such that the EM brake may open after receiving power via the first conductor and the second conductor.
