DRIVE FAULTS
93
ERROR/FAULT CODE
PROBABLE CAUSE/ — CORRECTIVE ACTION
908
OVER TEMPERATURE FAULT -
The calculated SCR junction
temperature is above 125 degrees Centigrade. This is calculated from
the thermistor heat sink measurement and measured armature output
current heating effects of SCRs. Possible causes:
Ambient temperature too high. Check for cause.
Clogged air filter in cabinet. Clean or replace air filter.
Clogged heat sinks. Clean Heatsink fins.
Cooling fan failure. Replace defective cooling fan(s) in power cube.
Note: This fault will not shutdown the Drive
.
909 RIPPLE
FAULT
- Repeated high peak to average motor armature
current. The cause of this condition may be defective hardware that
can be discovered through the PCU Diagnostics CDU function, #998.
It may also occur due to poor regulator tuning or other oscillatory
operation condition.
910 BLOWN
FUSE
FAULT - One or more of the three AC line fuses is
open. This condition is checked on power-up and upon request
through the PCU F#998 PCU Diagnostics function. Detection is
accomplished by measurements via voltage dividers on the Armature
Interface PCB, A2. Possible causes are;
One or more of AC input fuses are blown.
Power wiring problem-check wiring.
Faulty DSPR power relay.
911
SHORTED SCRS/DOUBLER FAULT
(DSD Power Down is required.)
One of the SCR/Doubler packs has a short circuit between the SCRS.
This condition is checked only upon request through the PCU #998
Diagnostics CDU function. The optional handheld PCDU will also
identify which SCR pair is bad.
912 OPEN
SCR
FAULT
(DSD Power Down is required.)
One of the SCRs does not conduct current. This condition is checked
only upon request through the PCU #998 Diagnostics CDU function.
The optional handheld PCDU will also identify which SCR pair is bad.
Check for faulty SCR gating leads.
915 PARAMETER
SETUP
FAULT
(DSD power down is required.)
One of the following parameters is not within the range of the chassis
hardware.
Rated Volts #7 or #9
Rated Current #3 or #50
Corrective action: Enter correct parameter data, save to NVRAM.
Reset the drive & re-start.
916 FORCING
FAULT
–
The prohibit rotation bit was removed with the
loop picked-up. This fault can only occur when using the handheld
PCDU.
