Fanuc alarm SP9037: SPEED DETECT PAR. ERROR
spindle alarm (serial spindle, alpha i) · Fanuc 0i-D
What it means
A speed detector pulse-count parameter exceeded the permitted range. The pulses-per-revolution figure configured for the feedback device is invalid, so the amplifier cannot convert pulse streams into speed units.
Likely causes
- Wrong speed-detector type selected in parameters
- Pulse count value mistyped after sensor replacement
- Corrupted parameter storage
