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 = Following spindle number
Definitions: If the spindles / axes differ strongly in their dynamic behavior during coupling, synchro-
nism cannot be achieved. The dynamics are dependent on many settings: default feedfor-
ward 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:
MA_VELO_FFW_WEIGHT, MA_FIPO_TYPE, VEL_FFW_TIME,
MA_EQUIV_SPEEDCTRL_TIME, MA_POSCTRL_GAIN, AX_JERK_TIME,
STIFFNESS_DELAY_TIME, PROFIBUS_ACTVAL_LEAD_TIME,
PROFIBUS_OUTVAL_DELAY_TIME, CTRLOUT_LEAD_TIME
Reactions: - 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 machine data 11410
SUPPRESS_ALARM_MASK Bit21 = 1.
Program Con- Clear alarm with the Delete key or NC START.

Channel %1 block %2 following spindle %3 No dynamic response for supplemen-
tary 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 spin-
dle is already rotating at maximum speed. In the part program a deadlock might occur.
The alarm can be suppressed with machine data 11410 SUPPRESS_ALARM_MASK
bit26 = 1.
Reactions: - Alarm display.
Remedy: Reduce the speed of the master spindle
Program Con- Clear alarm with the Delete key or NC START.

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
machine data 35220 ACCEL_REDUCTION_SPEED_POINT. If the situation is mastered
by the user, the alarm can be suppressed with machine data 11410
SUPPRESS_ALARM_MASK Bit25 = 1.
Reactions: - 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.
