3.2 Linear encoder manufactured by Heidenhain
Cause
• Encoder cable disconnection and short-circuit
• Problems in the power supplied to the linear
encoder
• Dirt on the scale reading surface or head reading
surface
• The head mounting position including the gap are
outside of specifications.
• Dirt on the scale reading surface or head reading
surface
• The head mounting position including the gap are
outside of specifications.
• Dirt on the scale reading surface or head reading
surface
• The head mounting position including the gap are
outside of specifications.
• Encoder cable disconnection and short-circuit
• Problems in the power supplied to the linear
encoder
• Encoder cable disconnection and short-circuit
• Problems in the power supplied to the linear
encoder
• Overspeed of the head during operation
Check/action method
If there is a problem with the encoder cable, replace or repair
the cable.
Check if the encoder cable is connected correctly.
Check for flaws and dirt on the scale surface, then wipe the
reading surface of the scale and head with a clean cloth or by
other means as necessary.
Check if the gap between the scale and head satisfies the
specifications.
