Remedy: - Program a GET for the master spindle/axis in the NC program before activating the coupling, 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.
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 MD30200
$MA_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
MD34060 $MA_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 MD34060
$MA_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
Definitions: The displayed spindle has been programmed as spindle or as axis even though a positioning opera-
tion is still running from the previous block (with SPOSA ... spindle positioning beyond block limits).
Example:
N100 SPOSA [2] = 100
:
N125 S2 = 1000 M2 = 04 ; Error, if spindle S2 from block N100 is still running!
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
