PULSE MISS(INT)

Was bedeutet 366 ?

This alarm on Fanuc Series 0i-D/0i Mate-D with αi/βi Pulsecoders indicates a small internal signal amplitude from the built-in Pulsecoder. This can be caused by the Pulsecoder itself failing or by external electrical noise affecting the signal integrity.

• Internal failure of the Pulsecoder causing weak signal output.
• Electrical noise interfering with the Pulsecoder signal lines.
• Damaged or degraded Pulsecoder cable reducing signal amplitude.

1. 1

   Inspect the Pulsecoder cable for any damage, proper shielding, and secure connections at both the Pulsecoder and the servo amplifier.

2. 2

   Check for and eliminate potential sources of electrical noise (e.g., power cables, induction) in the vicinity of the Pulsecoder and its cabling.

3. 3

   Verify the supply voltage to the Pulsecoder, ensuring it is within specified limits as per the wiring diagram.

4. 4

   If cabling, noise, and supply voltage are confirmed to be correct, replace the Pulsecoder unit.
