Claim 16:
17. A method of enabling a control circuit in a distributed motor drive, the method comprising the steps of:
selectively receiving a DC bus voltage and a DC control voltage at a DC bus input for the distributed motor drive;
transmitting the DC bus voltage and the DC control voltage according to which is present at the DC bus input from the DC bus input to an input of a power supply present in the distributed motor drive;
generating at least one motor drive control voltage with the power supply as a function of either the DC bus voltage or the DC control voltage according to which is present at the input of the power supply; and
enabling the control circuit with the at least one motor drive control voltage generated with the power supply.
