 None  System fault  Fault  Trouble  Quick stop by trouble  Warning locked  Warning  Information
Cause Remedy
• Encoder signal interferences (EMC).
• Encoder cable interrupted.
• Encoder defective.
• Faulty parameter setting of the encoder.
Note: This information is always supplied together with
the "I/O error - encoder communication" error message
and is entered in the logbook even if the encoder
monitoring is deactivated ( C00580 ).
• Check encoder cable, use shorter encoder cable if
required.
• Check encoder.
• Check parameter setting ( C00420 , C00421 , C00422 ).
