Overview of Alarms
NCK alarms
Definitions: The gear stage required for axis mode has not been installed.
A gear stage has been configured in MR35014 $MA_GEAR_STEP_USED_IN_AXISMODE, in which
the spindle is to be in axis mode. This gear stage is checked whenever the spindle is switched into
axis mode. The configured gear stage is compared with the gear stage output by the PLC (NC/PLC
interface signal DB31, ... DBX16.0. - .2 (Actual gear stage A through C)).
This alarm will be output if the gear stages are not the same.
Reaction: Interface signals are set.
Alarm display.
Remedy: Program M70 before the switch to axis mode. The gear stage configured in MD35014
$MA_GEAR_STEP_USED_IN_AXISMODE is then automatically loaded.
No gear stage change is required if the configured gear stage is aleady active. M40 remains active
beyond the gear stage change.
Consider MD20094 $MC_SPIND_RIGID_TAPPING_M_NR.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22030 [Channel %1: ] Block %2 following spindle %3 Impermissible
programming
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Spindle
Definitions: With synchronous spindle-VV-coupling an additional motion for the following spindle can only be pro-
grammed with M3, M4, M5 and S... The paths created by specified positions cannot be maintained
safely for a velocity coupling, especially if a position control is missing. If dimensional accuracy or
reproducibility are not important, the alarm can be suppressed with MD11410
$MN_SUPPRESS_ALARM_MASK Bit27 = 1.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Use synchronous spindle-DV-coupling or program direction of rotation and speed.
Program Con- Clear alarm with the RESET key. Restart part program
tinuation:
22033 [Channel %1: ] Block %2 Axis/spindle %3 'Correct synchronism'
diagnostics %4
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis/spindle number
%4 = Diagnostics
Definitions: The following situation occurred during 'Correct synchronism':
- Diagnosis 1: An existing override motion is terminated on key reset.
- Diagnosis 2: The override motion has been deleted.
- Diagnosis 3: Writing of override value not allowed. Synchronism override is deleted.
- Diagnosis 4: Override motion is stopped temporarily (e.g. G74 reference point approach)
- Diagnosis 5: Delay of override motion: acceleration capacity used up by other motions.
- Diagnosis 6: Delay of override motion: velocity used up by other motions.
- Diagnosis 7: Delay of override motion: the maximum speed is limited to 0. System variable
$AC_SMAXVELO_INFO[n] shows the reason for this.
- Diagnosis 8: Delay of override motion: the maximum acceleration capacity is limited to 0.
$AC_SMAXACC_INFO[n] shows the reason for this.
MD11411 $MN_ENABLE_ALARM_MASK activates this alarm:
- Bit 9 = 1 for diagnosis 1 to 6
- Bit 12 = 1 for diagnosis 7 to 8
Reaction: Alarm display.
Remedy: Deactivate the alarm with MD 11411 $MN_ENABLE_ALARM_MASK Bit9 = 0 or Bit12 = 0.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
