Fault Message/Warning Cause Remedy
476 Wake and Shake. Fine-
coarse delta too large.
The angle difference between the coarse
and fine calculation was larger than 72
deg.
Modify WS.IMAX or WS.T and
try again.
478 Wake and Shake. Over-
speed.
Warning issued prior to fault.
WS.VTHRESH was exceeded. Increase WS.VTHRESH value
or reduce WS.IMAX or WS.T.
479 Wake and Shake. Loop
angle delta too large.
Warning issued prior to fault.
The angle between complete loops was
larger than 72 deg.
Modify WS.IMAX or WS.T and
try again.
501 Bus over voltage.
Warning issued prior to fault.
Bus voltage too high. Usually, this prob-
lem is load related.
Reduce load or change motion
profile. Check system regen
capacity; add capacity if
needed. Check mains voltage.
502 Bus under voltage.
Warning issued prior to fault.
Bus voltage below threshold value. Check mains voltage.
503 Bus capacitor overload.
Warning issued prior to fault.
Single phase AC input on a drive only
rated for three-phase input or excessive
single-phase power load.
Check mains voltage.
504 to
518
Internal supply voltage fault Internal supply voltage fault detected Check wiring for elec-
tromagnetic compatibility
(EMC). If issue persists
exchange drive.
519 Regen short circuit. Regen resistor short circuit. Regen IGBT short circuit. Con-
tact technical support.
520 Regen overload. Regen resistor overload. Motor is being overhauled or
motor is being stopped too
quickly.
521 Regen over power.
Warning issued prior to fault.
Too much power stored in regen
resistor.
Increase regen resistor capac-
ity.Either get larger brake
resistor or use DC bus sharing
to dissipate power..
523 Bus over voltage FPGA Bus over voltage hard fault. Check mains voltage and check
system brake capacity.
524 Drive foldback.
Warning issued prior to fault.
Maximum drive power has been
exceeded. The power has been limited
to protect the drive.
Motion requires too much power.
Change profile to reduce load .
525 Output over current. Current exceeds drive peak. Check for short or feedback
faults.
526 Current sensor short circuit. Current sensor short circuit. Restart drive. If issue persists,
contact technical support.
527 Iu current AD converter
stuck.
Hardware failure detected. Restart drive. If issue persists,
contact technical support.
528 Iv current AD converter
stuck.
Hardware failure detected. Restart drive. If issue persists,
contact technical support.
529 Iu current offset limit
exceeded.
Hardware failure detected. Restart drive. If issue persists,
contact technical support.
530 Iv current offset limit
exceeded.
Hardware failure detected. Restart drive. If issue persists,
contact technical support.
