8–2 Troubleshooting
COMM LED
The COMM LED provides status information on module operations.
Table 8.A shows how to use the LED to detect and correct common
operating problems.
Table 8.A
COMM LED Indications
FAULT LED
When the FAULT LED lights red, a drive fault (including Fatal Error ) ,
or an option board fault is present. Drive fault codes can be read by
accessing drive parameter P07 - [Last Fault].
Refer to Tables 8.B and 8.C for fault descriptions/actions.

Fault Codes
1 Refer to the 160 SSC™ Variable Speed Drive (Series C) User Manual for the most current fault code
information.
Color State What It Means: What To Do:
Green Off No communication takes place,
No power. Check Power Supply,
Network Configuration
steady Communication ok,
data is exchanged No action required.
Red steady Diagnostics failed at power-up
or Fatal Error Cycle power to the drive. If problem
persists, exchange PD1 Module
flashing A cascade of 5 or 6 flashs means
Profibus configuration fault.
Any other flashs indicate Fatal Error
Check Network Configuration,
Profibus Master Setup and
SSC160 Setting (Section 5)
Exchange PD1 Module
Fault Code Fault Indication Description Corrective Action
00 No Fault The drive is currently not faulted. No action required.
03 Power Loss Fault DC Bus voltage remains below 85% nominal on
power up for longer than 5 seconds. Monitor incoming AC line for low voltage or line power
interruption.
04 Undervoltage Fault DC Bus voltage fell below the minimum value
while the motor was running. Monitor incoming AC line for low voltage or line power
interruption.
05 Overvoltage Fault DC Bus maximum voltage exceeded. Bus overvoltage caused by motor regeneration.
Extend the decel time, or install dynamic brake option
or external capacitor module.
06 Motor Stall Fault Motor has stalled. Motor load is excessive. Longer accel time or reduced load required.
07 Motor Overload Fault Internal electronic overload trip. Excessive
motor load exists. Reduce motor load.
08 Overtemperature Fault Excessive heat detected. Clear blocked or dirty heat sink fins. Check ambient
temperature. Check for blocked or non-operating fan.
11 Operator Fault The keypad has been removed while the drive
is powered. Clear the fault. Do not remove the keypad
underpower.
12 Overcurrent Fault Overcurrent detected in hardware trip circuit. Check short circuit at the drive output or excessive
load conditions at the motor.
20 Drive Overload Fault An internal electronic overload trip has
occurred. The drive is overheating. Clear blocked or dirty heat sink fins. Check ambient
temperature. Check for blocked or non-operating fan.
22 Drive Reset Stop input not present. Check stop input at TB3 terminal 8.
32 EPROM Fault EPROM has invalid data. Reset EPROM using P56 - [Reset Functions].
33 Max Retries Fault Drive did not reset fault within the max retries
specified. Repair system fault.
38 Phase U Fault Phase to ground fault detected between drive
and motor phase U. Check wiring between drive and motor. Check motor
for grounded phase.
