Retrofit a measuring system.
Clear alarm with the RESET key. Restart part program
No spindle stop for a block change
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 S2 is still running from block N100!
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
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
Clear alarm with the RESET key. Restart part program
Reference mark not found
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=...).
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
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.
Clear alarm with the RESET key. Restart part program
No transition from speed control mode to position control mode
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.
- NC Start disable in this channel.
- Interface signals are set.
- Alarm display.
- NC Stop on alarm.
