22050 Channel %1 block %3 spindle %2 no transition from speed control mode
to position control mode
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
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.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Spindle without attached encoder: Any NC language elements requiring the encoder signals must not
be used.
Spindle with attached encoder: Enter the number of spindle encoders used in the MD NUM_ENCS.
Program Clear alarm with the RESET key. Restart part program
Continuation:
22051 Channel %1 block %3 spindle %2 reference mark not found
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
Definitions: When referencing, the spindle turned through a greater distance than given in the axis-specific
machine data 34060 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=...).
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Please inform the authorized personnel/service department. Check and correct the machine data
34060 REFP_MAX_MARKER_DIST. The value entered states the distance in [mm] or [degrees]
between 2 zero markers.
Program Clear alarm with the RESET key. Restart part program
