Abstract
A system and method is provided for controlling the speed of the compressor to ensure adequate lubrication oil is provided to the components of the compressor. During operation of a capacity control program for the compressor, a preselected operating parameter of the compressor or motor drive is measured. The measured preselected operating parameter is compared to a preselected range for the operating parameter. If the measured preselected operating parameter is not within the preselected range, the output frequency of the capacity control program can be increased to provide proper lubrication for the components of the compressor.
