Definitions: The current position is not referenced with the MS position although reference is made to
it.
Reactions: - Alarm display.
Remedy: Correct NC part program. Create the zero mark synchronization by positioning, by rota-
tion (at least 1 revolution) in speed control mode or G74 before switching the alarm gener-
ating function on.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22060
Channel %1 position control expected for axis/spindle %2
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The programmed coupling type (DV, AV) or the programmed function requires position
control.
Reactions: - Alarm display.
Remedy: Activate position control, e.g. by programming SPCON.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
22062
Channel %1 axis %2 reference point approach: zero marker search velocity (MD) is
not reached
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The configured zero marker search velocity is not reached.
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 active spindle speed
limitations. Configure a lower zero marker search velocity
$MA_REFP_VELO_SEARCH_MARKER. Check the tolerance range for the actual veloc-
ity $MA_SPIND_DES_VELO_TOL. Set a different referencing mode
$MA_ENC_REFP_MODE != 7.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
22064
Channel %1 axis %2 reference point approach: zero marker search velocity (MD) is
too high
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The configured zero marker search velocity is too high. The encoder limit frequency is
exceeded for the active measuring system.
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. Configure a lower zero
marker search velocity $MA_REFP_VELO_SEARCH_MARKER. Check the encoder fre-
quency configuration $MA_ENC_FREQ_LIMIT and $MA_ENC_FREQ_LIMIT_LOW. Set
a different referencing mode ($MA_ENC_REFP_MODE != 7).
Program Con- Clear alarm with the RESET key. Restart part program
