Abstract
A method for providing a compatible interface between a motor control circuit and a system controller is described. The method includes determining which signals in the interface have incompatible voltage requirements, and inserting a series resistance in an interface extending between the motor control circuit and the system controller for each signal determined to have incompatible voltage requirements therebetween.
Claims16
A passive interface for utilization between a system controller and a variable speed motor (VSM) controller for an electronically controlled VSM, said passive interface comprising:
- a first plurality of conductors, each conductor in said first plurality of conductors configured to directly connect an output of the system controller to a corresponding input of the VSM controller, said first plurality of conductors configured to provide an operating power to the VSM controller;
- and
- a second plurality of conductors, each conductor in said second plurality of conductors separately connecting a signal output of the system controller to a respective input of the VSM controller, each conductor in said second plurality of conductors comprising a series resistor therein for passively reducing a voltage level of signals originating at the system controller, each series resistor comprising an electrical resistance that corresponds to a predefined voltage level of the respective input of the VSM controller.
A system for controlling an electronically controlled variable speed motor (VSM) including a motor controller, said system comprising:
- a system controller;
- and
- a passive interface electrically coupling said system controller to the motor controller, said passive interface comprising:
- a first plurality of conductors each configured to directly connect an output of said system controller to a corresponding input of the motor controller, said first plurality of conductors configured to provide an operating voltage to the motor controller;
- and
- a second plurality of conductors each comprising a series resistor therein for passively reducing a voltage level of signals originating at said system controller, each of said second plurality of conductors configured to connect a signal output of said system controller to a respective input of the motor controller, each series resistor comprising an electrical resistance that corresponds to a predefined voltage level of the respective input of the motor controller.
