2.2.3 Hardware faults and contamination signal
Function
Monitoring of the measuring systems of a machine axis with regard to:
• Hardware faults
• Contamination of the measuring system
Fault case
In the event of an error:
• Alarm: "25000 Axis <
Axis identifier
> Hardware fault active encoder"
• Alarm: "25001 Axis <
Axis identifier
> Hardware fault passive encoder"
• Alarm: "25010 Axis <
Axis identifier
> Contamination of measuring system"
• Alarm: "25011 Axis <
Axis identifier
> Contamination of passive encoder"
• In the event of a fault in the active measuring system:
– The affected axis is stopped via the configured braking ramp in follow-up mode:
MD36610 $MA_AX_EMERGENCY_STOP_TIME
(Time for braking ramp when an error occurs)
– If the axis/spindle is involved in interpolation with other axes/spindles, these are brought
to a standstill with rapid stop (set velocity = 0).
• In the event of a fault in the passive measuring system: Only alarm display
• For hardware faults, the referencing status of the measuring system is reset:
DB31, ... DBX60.4 / 60.5 = 0 (referenced/synchronized 1 / 2)
