Förklaring:
Overheating of the PTC1 probes detected.
Drive temperature too high.
Triggered by excessive motor current.
Braking too sudden or driving load.
Line voltage too high. Disturbed line supply.
Loss of one phase at drive output.
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.
Line supply too low. Transient voltage dip. Damaged precharge resistor.
Short-circuit or grounding at the drive output. Significant earth leakage current at the
drive output if several motors are connected in parallel.
Instability or driving load too high.
Special motor or motor whose power is not suitable for the drive. Motor not connected to
the drive.
The power card is not the one stored.
The power card is incompatible with the control card.
Communication fault between the internal cards.
