Fault tracing

Contents of this chapter

This chapter shows how to trace faults with the status LEDs on the Absolute Encoder
Interface module.

Diagnostic LEDs

The FEN-11 is equipped with two diagnostic LEDs. The STATUS LED describes the
status of the FEN-11 and the ENC ST LED the status of the encoders. Description of
the LED signals is presented below.

Description

Colour

Green

STATUS LED

Not initialized or communication fault to the drive

Orange

Not in use

Red

Encoder(s) OK

Green

ENC ST LED

TTL encoder (X41) fault

Red

Absolute encoder (X42) fault

Orange

TTL encoder fault X41 and absolute encoder X42
fault

Red/orange swapping

TTL encoder (X41) warning

Red flashing

Absolute encoder (X42) warning

Orange flashing

Incorrect encoder parameter configuration.

OFF

Note: This concerns FEN-11 usage with ACS880.

Note: When using FEN-11 with ACS880 the status of ENC ST LED is updated after
encoder fault reset is done.
