Frekvensomriktare: Felkod 15 - 28
Felkod: Visas i display: Förklaring:
15 [PTC1 overheat]
(OtF1)
Overheating of the PTC1 probes detected.
16 [Drive overheat]
(OHF)
Drive temperature too high.
17 [Motor overload]
(OLF)
Triggered by excessive motor current.
18 [Overbraking]
(ObF)
Braking too sudden or driving load.
19 [Mains overvoltage]
(OSF)
Line voltage too high. Disturbed line supply.
20 [1 motor phase loss]
(OPF1)
Loss of one phase at drive output.
21 [Input phase loss]
(PHF)
Drive incorrectly supplied or a fuse blown. Loss of one phase. 3-phase ATV71 used on a
single-phase line supply. Unbalanced load. This protection only operates with the drive on
load.
22 [Undervoltage]
(USF)
Line supply too low. Transient voltage dip. Damaged precharge resistor.
23 [Motor short-circuit]
(SCF1)
Short-circuit or grounding at the drive output. Signicant earth leakage current at the
drive output if several motors are connected in parallel.
24 [Overspeed]
(SOF)
Instability or driving load too high.
25 [Auto-tuning]
(tnF)
Special motor or motor whose power is not suitable for the drive. Motor not connected to
the drive.
26 [Rating error]
(InF1)
The power card is not the one stored.
27 [Incompatible PB]
(InF2)
The power card is incompatible with the control card.
28 [Internal serial link]
(InF3)
Communication fault between the internal cards.
