7.2.3 Position control with incremental encoders
Symptom Cause
• Interference pulse in the encoder cable
• No reproducible precision when
approaching the position,
• At all speeds
– Interference pulse in the encoder cable
• Only at high speed (n > 1000 rpm)
– Pulse number of the encoder too large in association with the
length of the encoder cable pulse frequency too high
– Encoder not mounted correctly / loose

7.2.4 Position control with absolute encoders
Symptom Cause
• Actual position value always runs to
the same value and then no longer
changes
• Encoder connection faulty
• Position not always found at the same
place, axis sometimes jumps
backwards and forwards.
• Axis jams
• Encoder not mounted correctly / loose
• Position value jumps or does not
match the number of revolutions of
the encoder
Check the absolute encoder:
– Remove the encoder
– Set the speed ration and reduction to "1" (P607, P608)
– Manually rotate the encoder shaft. The displayed position must
match the number of revolutions of the encoder, otherwise the
encoder has a malfunction.
