Integrated drive motor power interface

摘要

An integrated drive motor (IDM) power distribution architecture utilizes an IDM power interface module (IPIM) to create a control voltage that is distributed to all the IDMs in a network. This power distribution may be accomplished along a hybrid cable, for example, that includes both signal conductors and power conductors. The IPIM is capable of detecting short circuits and/or overload conditions and disabling the power supply to the IDMs. Additionally, a second power supply may be utilized in the IPIM such that when the power supply to the IDMs is deactivated, the IPIM may remain functional, for example, to report one or more fault conditions to the user. Additionally, this reporting of fault status may be accomplished via a user display integrated with or coupled to the IPIM.

主权项

1. A motor drive system, comprising:
an integrated power interface module (IPIM) comprising circuitry configured to communicate with at least one networked integrated motor drive; an integrated motor drive (IDM) coupled to the IPIM and configured to communicate with the IPIM during operation; and an automation controller coupled to and configured to communicate with both the IPIM and the IDM during operation; wherein, in operation, the IPIM receives operational data from the IDM and communicates operational data to the automation controller, and wherein the IDM is also configured to communicate operational data to the automation controller, and wherein in the event of inoperability of the IDM, operational data is still communicated from the IPIM to the automation controller.
