484 CbFan RemainLife
Cabinet Fan Remaining Life
Remaining number of hours until estimated end of life for cabinet fans, and is the
difference between P482 [CbFan TotalLife] and P483 [CbFan ElpsdLife]. All negative
values of this parameter need to be treated as excessive use (> 100%), and trigger the
appropriate action chosen by P486 [CbFan EventActn].
Frame 8 drives have a single converter, and therefore have a single cabinet fan. The
value of this parameter reflects the remaining life of that fan.
Frame 9 drives have two converters, and therefore two cabinet fans. Frame 10 drives
have three converters, and therefore three cabinet fans. For frame 9 and 10 drives, the
value of this parameter reflects the shortest remaining life of all the cabinet fans.

486 CbFan EventActn
Cabinet Fan Event Action
Configures the response to a cabinet fan event, which occurs when P485 [CbFan
EventLevel] is met or exceeded.
“Ignore” (0) – No action is taken.
“Alarm” (1) – Type 1 alarm indicated.
“Flt Minor” (2) – Minor fault indicated. If running, drive continues to run.
Enable with P950 [Minor Flt Cfg]. If not enabled, acts like a major fault.
“FltCoastStop” (3) – Major fault indicated. Coast to Stop.
“Flt RampStop” (4) – Major fault indicated. Ramp to Stop.
“Flt CL Stop” (5) – Major fault indicated. Current Limit Stop.

quality or vibration.

489 HSFan TotalLife
Heatsink Fan Total Life
Total number of hours expected over the life of a single heatsink fan. Calculated as a
function of fan manufacturer’s life data (from frame rating table), P470
[PredMaintAmbTemp] and P488 [HSFan Derate].

490 HSFan ElpsdLife
Heatsink Fan Elapsed Life
Accumulated hours of heatsink fan run time.
Use P472 [PredMaint Reset] to reset this parameter.
Frame 8 drives have a single inverter, and therefore have a single
heatsink fan. The value of this parameter reflects the elapsed life of that
fan.
Frame 9 drives have two inverters, and therefore two heatsink fans.
Frame 10 drives have three inverters, and therefore three heatsink
fans. For frame 9 and 10 drives, the value of this parameter reflects
the longest elapsed life of all the heatsink fans.
Individual elapsed life values are available at parameters 128 [I1
HSFanElpsdLif], 228 [I2 HSFanElpsdLif] and 328 [I3 HSFanElpsdLif] in
port 10.
