1. A motor drive system for operating an electric motor, the motor drive system comprising:
- a power conversion system operative to selectively provide electrical power from a power source to an electric motor according to at least one control input;
a control system providing the control input to the power conversion system for controlling operation of the electric motor; and
an information capture system comprising;
an information capture component operative to capture motor drive information in real time, wherein the captured motor drive information includes at least one of a firmware value from the control system, a firmware state from the control system, control program states from the control system, and breakpoint information from the control system, anda non-volatile memory component to store the captured information in real time,wherein the non-volatile memory component is removable from the motor drive system,wherein the non-volatile memory component is a USB memory key.
