Abstract: Systems, methods, and devices are provided for coupling a direct current (DC) pre-charging circuit to a motor drive. In one embodiment, an industrial automation device may include an enclosed module that may include a pre-charge circuit. The pre-charge circuit may pre-charge a direct current (DC) bus. Further, the DC bus may couple to an inverter. The enclosed module may also include a power input that may couple the pre-charge circuit to a DC power source and an electrical output structure that may couple the pre-charge circuit to the inverter. Additionally, the pre-charge circuit may be removeably coupled to the inverter and the DC power source via a sliding action of the enclosed module.

Abstract: An electric motor drive system includes a fan configured to cool power electronic components of the electric motor drive system. The electric motor drive system also includes a temperature sensor disposed proximate an air inlet of the fan and configured to sense an ambient temperature of air entering the air inlet. In addition, the electric motor drive system includes a processor communicatively coupled to the temperature sensor and configured to determine at least one of a drive prognostic and a derating requirement based on the sensed ambient temperature.
