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
Color State What It Means:
Red Solid Cable disconnected or bad connection. Connect cable/check connections.
Application timed out.
Green Solid Cable is connected and module is ready. No action required.
Flashing Device is on-line and communicating.

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 Fault Codes
Description
The drive is currently not faulted.
DC Bus voltage remains below 85% nominal on
power up for longer than 5 seconds.
DC Bus voltage fell below the minimum value
while the motor was running.
DC Bus maximum voltage exceeded.
Motor has stalled. Motor load is excessive.
Internal electronic overload trip. Excessive
motor load exists.
Excessive heat detected.
Overcurrent detected in hardware trip circuit.
An internal electronic overload trip has
occurred. The drive is overheating.
Stop input not present.
EPROM has invalid data.
Drive did not reset fault within the max retries
specified.
Phase to ground fault detected between drive
and motor phase U.
Phase to ground fault detected between drive
and motor phase V.

Refer to the 160 User Manual for the most current fault code information.
What To Do:
Application did not access N41:0
before parameter 114 expired –
verify parameter 114 setting.
No action required.
Corrective Action
No action required.
Monitor incoming AC line for low voltage or line power
interruption.
Monitor incoming AC line for low voltage or line power
interruption.
Bus overvoltage caused by motor regeneration.
Extend the decel time, or install dynamic brake option
or external capacitor module.
Longer accel time or reduced load required.
Reduce motor load.
Clear blocked or dirty heat sink fins. Check ambient
temperature. Check for blocked or non-operating fan.
Check short circuit at the drive output or excessive
load conditions at the motor.
Clear blocked or dirty heat sink fins. Check ambient
temperature. Check for blocked or non-operating fan.
Check stop input at TB3 terminal 8.
Reset EPROM using P56 - [Reset RS1].
Repair system fault.
Check wiring between drive and motor. Check motor
for grounded phase.
Check wiring between drive and motor. Check motor
for grounded phase.
