PULSE MISS(EXT)

Was bedeutet 383 ?

This alarm on Fanuc Series 0i-D/0i Mate-D indicates a small internal signal amplitude from a separate (external) detector. This can be caused by the detector itself failing, power supply issues, or external electrical noise affecting the signal integrity.

• Internal failure of the external detector causing weak signal output.
• Insufficient or unstable power supply voltage to the external detector.
• Damaged or degraded cable from the detector to the SDU, reducing signal amplitude.

1. 1

   Inspect the external detector's power supply voltage at the detector terminals to ensure it is within specified limits.

2. 2

   Verify the integrity of the cable connecting the detector to the SDU, checking for damage or signal attenuation.

3. 3

   Check for any significant electromagnetic interference (EMI) near the detector or its cabling that could affect signal amplitude.

4. 4

   If power, cabling, and noise issues are ruled out, replace the external detector unit.
