ABSTRACT:
Responsive to a request for refrigeration, a start up sequence is initiated and, if start up is achieved, a number of motor and compressor parameters of operation are sensed for controlling and protecting the compressor. Depending upon the nature of the sensed conditions, if necessary, the motor, and thereby the compressor, is either disabled or corrective action is initially taken to bring the parameters within an acceptable range. If corrective action is ineffective, the motor and thereby the compressor, is disabled.
