Appendix C Application Notes
Predictive Maintenance for Floor Mount Drives (Frames 8…10)
There can be multiple power structures in parallel on floor mount drives; and
therefore, multiple sets of fans, which make the predictive maintenance more
complicated than on wall mount drives.
To minimize the number of parameters, the parallel inverters, converters, and
precharge units do not have separate [Total Life] and [Remaining Life]
parameters. You must calculate the individual [Remaining Life] values in the
controller.
A frame 10 drive has three power structures, and three sets of cabinet fans,
heatsink fans, and internal stirring fans.
These parameters are available for the cabinet fans.
Table 26 - Cabinet Fan Parameters
Node Parameter No. Parameter Name Description
0 482 CBFan TotalLife Displays the expected lifespan for a cabinet fan.
0 483 CBFan ElpsdLife Displays the greatest expended life of a cabinet fan.
0 484 CBFan RemainLife Displays the difference between P482 [CBFan TotalLife] and
P483 [CBFan ElpsdLife].
11 138 C1 CBFanElpsdLife Displays the expended life of the fans on cabinet 1.
11 238 C2 CBFanElpsdLife Displays the expended life of the fans on cabinet 2.
11 338 C3 CBFanElpsdLife Displays the expended life of the fans on cabinet 3.
