Chapter 7 – Fault Tracing
ACA 635 IGBT Supply Sections 7-5
FAN FLT
Par. 9.11 bit 5 Fan is not rotating, or contactor connection is
loose. Check the acknowledge circuit connection to
the digital input DI1.
Check the condition of the bearings of the fan
motor by rotating fan motor manually. If the
bearings are faulty replace the fan (available as
spare part).
Replace the fan if trippings continue and the
bearings are OK.
IO FAULT
Par. 9.02 bit 6 I/O communication fault or error detected on
CH1. This can be caused by a fault in the NIOC
board or a faulty/loose fibre optic cable
connection. Check for loose connections between the
NIOC and NAMC board.
Test with new fibre optic cables.
If the fault is still active, replace the NIOC
board.
MAIN CNT FLT
Par. 9.11 bit 6 Main contactor is not functioning properly, or
loose wiring. Check main contactor control circuit wiring and
signal wiring.
Check main contactor control voltage level
(should be 230 V).
NET VOLT FLT
Par. 9.11 bit 9 Mains voltage is out of allowable range during
synchronisation or ID Run. Trip limits are 208 V
for 415 V units, 250 V for 500 V units and
345 V for 690 V units. Check mains voltage.
Start again.
OVER SWFREQ
Par. 9.02 bit 9 Switching overfrequency fault. This may be due
to a hardware fault in the electronic boards. Replace the NAMC board.
Replace the NINT board.
On units with parallel connected inverters,
replace the NPBU board.
OVERCURRENT
Par. 9.01 bit 1
Par. 9.11 bit 1 Input current is excessive. The overcurrent trip
limit is 0.98
×
(Par. 4.08 CONV MAX
CURRENT). The trip limit is approximately
190 % of the converter nominal current
I
1N
(Par. 4.05 CONV NOM CURRENT).
Check motor load.
Check supply voltage.
Check that there is no power factor
compensation capacitors in the supply.
Check ISU power semiconductors and current
transducers.
PPCC LINK
Par. 9.02 bit 11 NINT board current measurement or
communication fault between the NAMC and
NINT boards.
The fault indication is not activated, when the
DC link voltage is disconnected, but the NAMC
board has an external power supply. The
indication is activated when the charging is
completed and the DC link voltage is “high”. Check the fibre optic cables connected
between the NAMC and NINT boards. In
parallel connected inverters, also check the
cabling on the NPBU-xx board.
If the fault is still active, replace the NPBU
board (only with parallel connected inverters),
NAMC and NINT board (in this order) until the
fault disappears.
Test with new fibre optic cables in the PPCC
(power plate control board) link.
SHORT CIRC
Par. 9.01 bit 0 Short-circuit current has been detected on a
power plate. Measure the resistance of the power plate(s).
If a faulty power plate is detected, replace the
power plate and the NINT and NGDR boards,
or change the whole converter phase module.
Check the main circuit.
