1 Overview
Comprehensive current diagnosis Type
• Motor malfunction (called "degradation level") can be detected by measuring and monitoring the
current including harmonic components.
• The degradation level is the conversion of the degree of deviation of the current waveform
between the normal motor and the abnormal motor in numerical values.
• The K6CM can also detect motor peripheral malfunctions affecting the rotating shaft of the motor.
(1) Motor and load are normal.
(2) An abnormality is occurring.
