AKD PDMM User Guide | 15.1 Fault and Warning Messages
Fault Message/Warning Cause Remedy
F501
n501
Bus over voltage. Bus voltage too high. Usually,
this problem is load related. Reduce load or change motion
profile. Check system regen
capacity; add capacity if
needed. Check mains voltage.
F502 Bus under voltage.
Warning issued prior to fault.
Bus voltage below threshold
value. Check mains voltage.
F503
n503
Bus capacitor overload. Single phase AC input on a
drive only rated for three-
phase input or excessive sin-
gle-phase power load. Check mains voltage.
F519 Regen short circuit. Regen resistor short circuit. Regen IGBT short circuit. Con-
tact technical support.
F521
n521
Regen over power. Too much power stored in
regen resistor. Either get larger regen resistor
or use DC bus sharing to dis-
sipate power.
F523 Bus over voltage FPGA Bus over voltage hard fault. Check mains voltage and check
system brake capacity.
F524
n524
Drive foldback. 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 .
F525 Output over current. Current exceeds drive peak. Check for short or feedback
faults.
F526 Current sensor short circuit. Current sensor short circuit. Restart drive. If issue persists,
contact technical support.
F527 Iu current AD converter stuck. Hardware failure detected. Restart drive. If issue persists,
contact technical support.
F528 Iv current AD converter stuck. Hardware failure detected. Restart drive. If issue persists,
contact technical support.
F529 Iu current offset limit
exceeded. Hardware failure detected. Restart drive. If issue persists,
contact technical support.
F530 Iv current offset limit
exceeded. Hardware failure detected. Restart drive. If issue persists,
contact technical support.
F531 Power stage fault. Hardware failure detected. Restart drive. If issue persists,
replace drive.
