Overview of Alarms
Reactions: - Interpreter stop
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
Remedy: Retrofit a measuring system.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
111106
No spindle stop for a block change
Definitions: The displayed spindle has been programmed as spindle or as axis even though a posi-
tioning operation is still running from the previous block (with SPOSA ... spindle position-
ing beyond block limits).
Example: N100 SPOSA [2] = 100 etc.,
N126 S2 = 1000 M2 = 04 Error, if the spindle S2is still running from block N100!
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Before programming the spindle/axis again using the SPOSA instruction, a WAITS com-
mand should be activated in order to wait for the programmed spindle position.
Example: N100 SPOSA [2] = 100 etc., N125 WAITS (2) N126 S2 = 1000 M2 = 04
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
111107
Reference mark not found
Definitions: When referencing, the spindle turned through a greater distance than given in the axis-
specific machine data 34,060 REFP_MAX_MARKER_DIST, without receiving a reference
mark signal. The check is performed for spindle positioning with SPOS or SPOSA when
the spindle has not previously run with speed control (S=...).
Reactions: - NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: Check and correct the MD 34 060 REFP_MAX_MARKER_DIST. The value entered
states the distance in [mm] or [degrees] between 2 zero markers.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
111108
No transition from speed control mode to position control mode
Definitions: An oriented spindle stop (SPOS/SPOSA) has been programmed or the position control of
the spindle was switched on with SPCON but no spindle encoder has been defined.
When switching on the position control, the spindle speed is greater than the limiting
speed of the measuring system.
Reactions: - NC Start disable in this channel.
