Inspection item6.1.4 Display of the life of the inverter partsThe self-diagnostic alarm is output when the life span of the control circuit capacitor, cooling fan, each parts of theinrush current limit circuit is near to give an indication of replacement time .The life alarm output can be used as a guideline for life judgement.PartsJudgement levelMain circuit capacitor 85% of the initial capacityControl circuit capacitor Estimated 10% life remainingInrush current limit circuit Estimated 10% life remaining (Power on: 100,000 times left)Cooling fanLess than 50% of the predetermined speedFor the life check of the main circuit capacitor, the alarm signal (Y90) will not be output if a measuring method of (2) isnot performed. (Refer to page 113.)(1) Display of the life alarm· Pr. 255 Life alarm status display can be used to confirm that the control circuit capacitor, main circuit capacitor,cooling fan, and each parts of the inrush current limit circuit has reached the life alarm output level.bit 157 00 0 0 0 0 0 0 0 0 0 0 0 1 0 0 1Pr. 255 Bit(decimal) (binary)15 111114 111013 110112 110011 101110 10109 10018 10007 01116 01105 01014 01003 00112 00101 00010 0000Inrush CurrentLimit Circuit Lifebit0 Control circuit capacitor lifebit1 Main circuit capacitor lifebit2 Cooling fan lifebit3 Inrush current limit circuit lifeCoolingFan LifeMain CircuitCapacitor Life• Pr.255 readControl CircuitCapacitor Life: with alarm, : without alarm• Pr.255 setting readBit image is displayedin decimalPOINTLife check of the main circuit capacitor needs to be done by Pr. 259.
