Known encoder coupling errors

Mechanical encoder coupling errors

• Discontinuities in mechanical transmission elements (e.g. grounded cable hoists or drums unwinding that is unnoticed by the encoder)
• Incorrect friction wheel diameter, e.g. due to wear (incorrect gear unit ratio)
• Slipping of the encoder or motor mode in the case of frictional connections due to insufficient friction force
• Drifting of the encoder sensor head or the measuring scale or the laser mirror

Electronic encoder coupling errors

• Freezing of the encoder signal without notification of an encoder error

Special coupling errors or operating states on the measuring scale

• Measuring tape
• Measuring tape has moved out of place.
• Measuring tape has cracks.
• Measuring tape has zero ranges.
• Measuring tape is damaged or dirty.
• Laser light reflector
• Laser signal is interrupted or disturbed (e.g. by people or birds).
  INFORMATION: The detection of this brief interruption of the sensor signal in order to continue moving with the help of the motor encoder is in preparation.
