A pulse error occurred on the separate detector, indicating that expected pulses were not detected. This impacts the accuracy of position feedback from the external detector.
Click steps to track your progress.
Measure signal amplitude on external detector output terminals.
Inspect external detector encoder disk for scratches or misalignment.
Test external detector signal generation with diagnostic tools.
Install noise filters on power supply lines to the external detector.
Verify parameter P1-01 (Encoder Pulse Output) setting.
