Overview of Alarms
NCK alarms
22014 [Channel %1: ] Block %2. The dynamics of leading spindle %3 and
dependent spindle %4 is too variably
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Leading spindle number
%4 = Number of following spindle
Definitions: If the spindles / axes differ strongly in their dynamic behavior during coupling, synchronism cannot be
achieved. The dynamics are dependent on many settings: default feedforward control, parameter
block data, first of all the servo gain factor, symmetrizing time, etc., feedforward control mode and
feedforward setting parameter, FIPO mode, jerk filter and dynamic filter settings, DSC on/off. Among
these are the following machine data: MD32620 $MA_FFW_MODE, MD32610
$MA_VELO_FFW_WEIGHT, MD33000 $MA_FIPO_TYPE, VEL_FFW_TIME, MD32810
$MA_EQUIV_SPEEDCTRL_TIME, MD32200 $MA_POSCTRL_GAIN, MD32410
$MA_AX_JERK_TIME, MD32644 $MA_STIFFNESS_DELAY_TIME, MD37600
$MA_PROFIBUS_ACTVAL_LEAD_TIME, MD37602 $MA_PROFIBUS_OUTVAL_DELAY_TIME,
MD10082 $MN_CTRLOUT_LEAD_TIME
Reaction: Alarm display.
Remedy: Use spindles/axes with the same dynamics. If the differing settings have been selected on purpose,
the alarm can be suppressed with the MD11410 $MN_SUPPRESS_ALARM_MASK Bit21 = 1.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22015 [Channel %1: ] Block %2 following spindle %3 No dynamic response for
supplementary motion
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Number of following spindle
Definitions: The difference motion of the slave spindle cannot be executed due to a lack of available velocity. The
coupling consumes the entire available dynamic response. The slave spindle is already rotating at
maximum speed. In the part program a deadlock might occur. The alarm can be suppressed with
MD11410 $MN_SUPPRESS_ALARM_MASK bit26 = 1.
Reaction: Alarm display.
Remedy: Reduce the speed of the master spindle
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
22016 [Channel %1: ] Block %2 following spindle %3 in the range of reduced
acceleration capability
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Number of following spindle
Definitions: The following spindle is driven with position control. Additional motion components of the following
spindle shall not leave the linear range of the motor used. Otherwise deviations in the contour or servo
alarms may occur. Monitoring refers to the configuration in MD35220
$MA_ACCEL_REDUCTION_SPEED_POINT. If the situation is mastered by the user, the alarm can
be suppressed with MD11410 $MN_SUPPRESS_ALARM_MASK Bit25 = 1.
Reaction: Alarm display.
Remedy: Use coupling type VV and safeguard SPCOF for master and following spindle.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
2-350
