Rockwell Automation 160 RSI SERIAL COMM MODULE - Manual (Page 40)

9–2 Troubleshooting
READY LED
The green READY LED will illuminate whenever the RS1 Module is
connected to the drive and power is applied.
COMM LED
The COMM LED provides status information on module operations.
Table 9.A shows how to use the LED to detect and correct common
operating problems.
Table 9.A
COMM LED Indications
FAULT LED
When the FAULT LED is Red, a drive fault is present. Drive fault
codes can be read by accessing drive parameter P07 - [Last Fault].
Refer to Tables 9.B and 9.C for fault descriptions/actions.
Table 9.B
160 Drive
1 Fault Codes
1 Refer to the 160 User Manual for the most current fault code information.
Color State What It Means: What To Do:
Red Solid Cable disconnected or bad connection. Connect cable/check connections.
Application timed out.
Application did not access N41:0
before parameter 114 expired –
verify parameter 114 setting.
Green Solid Cable is connected and module is ready. No action required.
Flashing Device is on-line and communicating. No action required.
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.
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 RS1].
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.
39 Phase V Fault Phase to ground fault detected between drive
and motor phase V. Check wiring between drive and motor. Check motor
for grounded phase.
