(1)Operating life of parts are further lengthened
•Adoption of newly developed long life cooling fan (design life of 10 years*1) Longer operating life is further enhanced with the use of ON/OFF control of cooling fan. •Adoption of long life capacitor (design life of 10 years*1, 2)
A capacitor with specification of 5000 hours at 105˚C ambient temperature is adapted.
*1 Ambient temperature: yearly average 40˚C (free from corrosive gas, flammable gas, oil mist, dust and dirt) Since the design life is a calculated value, it is not a guaranteed value.
*2 Output current: 80% of the rated current of Mitsubishi standard 4P motor
(2)State of the art longevity diagnostic method
•Degrees of deterioration of main circuit capacitor, control circuit capacitor or inrush current limit circuit can be diagnosed by monitor.
•Trouble can be avoided with the
*Any of alarm for main circuit capacitor, control circuit capacitor, inrush current limit circuit and cooling fan can be output.
