Quattro DC Troubleshooting 
 
Name Description 
Possible Causes & Corrective Action 
Extrn Fault 2 
 
User defined external logic 
fault input 
...Closure of this contact will 
cause the drive to declare the 
fault
 
Check Parameter Settings and External Fault 
Signal Wiring
 
 
Check the correct logic input is configured for 
the correct TB1 terminal and set to EXTRN 
FAULT 2 (C2) 
 
Verify the source of the external fault signal. 
Extrn Fault 3 
 
User defined external logic 
fault input 
...Closure of this contact will 
cause the drive to declare the 
fault
 
Check Parameter Settings and External Fault 
Signal Wiring
 
 
Check the correct logic input is configured for 
the correct TB1 terminal and set to EXTRN 
FAULT 3 (C2) 
 
Verify the source of the external fault signal. 
Extrn / Fault 4 
 
User defined external logic 
fault input 
...Opening of this contact will 
cause the drive to declare the 
fault
 
Check Parameter Settings and External Fault 
Signal Wiring
 
 
Check the correct logic input is configured for 
the correct TB1 terminal and set to EXTRN 
/FLT 4 (C2) 
 
Verify the source of the external fault signal. 
Field Ground 
 
The hardware has detected a 
ground fault in the field circuit.  
The current going into the field 
coil F1 does not match the 
current returning from the field 
coil F2. 
Check Motor Field wiring 
 
Check motor field wiring and motor field for 
insulation breakdown, unintentional contact to 
other objects, or shorts 
 
Ensure proper connection of shield drain wires 
to chassis  
Possible bad current sensor 
Field I REG 
 
Measured field current does 
not match commanded field 
current.  OR no data update 
between processor PCBs. 
Check Parameter Settings 
 
Verify parameter settings for motor field control 
Check Motor Field Current Sensing   
 
Verify accuracy of motor field current sensing 
with a separate DC current ammeter 
 
Replace Field Control Module if there are 
significant differences 
 
If re-occurs or there are not significant 
differences increase stand-by field current 
setting to reduce current decay time 
 
Replace main processor PCBs if data updates 
to operator do not occur 
External Relay Timing 
 
Check for improper external relay timing 
Check Wiring 
 
Missing jumper wire at Customer Interface 
Board PCB, TB2 
Field IGBT 
 
A de-saturation condition has 
been detected on a field 
power bridge IGBT.  
Check motor field and wiring  
 
Verify motor field and motor wirings are not 
shorted 
 
If re-occurs and the motor field and wirings are 
okay, suspect a defective field module IGBT 
Field LOSS 
 
The field voltage has been 
above 25% of rated and the 
field current below 2% of rated 
for 1.5 seconds 
Check motor field and wiring  
 
Verify motor field and motor wirings are not 
open
