3-41-0 Drive fault
On
On
If an activation signal is sent to a device and
the device does not activate (machine motion
relay or in-rush relay for example) this fault will
occur.
3-42-0 5 or 24 VDC fault
(Test 5)
The 5 or 24 VDC supply from the flyback
circuit is out of range.
3-42-1 18 VDC fault
The 18 VDC supply from the flyback circuit is
out of range.
• Replace the power board.
3-43-0 Inverter capacitors
unbalanced
(Test 2)
Voltage across one or both inverter caps is
more than 25% different than nominal.
• CSA units have a 760 VDC bus voltage.
• Nominal is 380 VDC for each cap.
• Fault condition: < 275 or > 485 VDC
across either capacitor.
• CE units at 400 VAC have a 560 VDC bus
voltage.
• Nominal is 280 VDC for each cap.
• Fault condition: <200 or> 360 VDC across
either capacitor.
• Test the IGBT module.
• Test the inverter capacitors. (2200µF)
3-44-1 PFC over current
High current in the PFC/Boost circuit.
• Test the PFC IGBT.
• Replace it if faulty.
• If necessary, replace the power board.
