Reactions: - Interface signals are set.
- Alarm display.
- NC Stop on alarm.
Remedy: • Program a GET for the master spindle/axis in the NC program before activating the cou-
pling, or
• Assign the master spindle/axis to the channel that activated the coupling via PLC.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
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.
Reactions: - 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 sig-
nals must not be used.
Spindle with attached encoder: Enter the number of spindle encoders used in the MD
NUM_ENCS.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
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=...).
Reactions: - 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 Con- Clear alarm with the RESET key. Restart part program
tinuation:
22052
Channel %1 block %3 spindle %2 no standstill on block change
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Block number, label
