What an encoder alarm means on an injection moulding servo motor

An encoder alarm means the drive cannot read a valid position. Common causes are cable damage, loose connectors, contamination, encoder failure or wrong alignment. Star does encoder repair and encoder alignment.

01Guide

Encoder alarm

Cable and connector

Check for damage, loose pins and moisture first.

Encoder failure

A failed encoder needs repair or replacement.

Alignment

After a motor repair the encoder must be aligned to the rotor.

Drive side

Drive faults can also raise an encoder alarm; test both.
