Fagor alarm 3715: Overshooting in module compensation
CNC 8060/8065/8070 servo/feedback error · Fagor 8060/8065/8070
What it means
On position-Sercos rotary axes the CNC tracks module compensation absolutely; if the axis always moves in the same direction the accumulated compensation keeps growing until it overshoots the permitted range. A home search re-baselines the compensation and clears the condition.
Likely causes
- rotary axis operated unidirectionally for long periods without re-referencing
- axis never re-homed after commissioning changes
- incorrect module/360-degree handling in gearing parameters
