Fagor alarm 2025: Probe feedback error

What it means

Hardware-level probe monitoring on the 8055 reports that the tracing probe is not connected or that one of its conductors is miswired. The alarm behaves like a full hardware error: axes and spindle stop, enables cancel and the external emergency output activates.

Likely causes

• probe lead unplugged at the spindle-side coupler
• wiring error between probe and the dedicated probe input
• broken conductor in the probe cable
