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
machine data 11410 SUPPRESS_ALARM_MASK bit26 = 1.
Reaction: Alarm display.
Remedy: Reduce the speed of the master spindle
Program Clear alarm with the Delete key or NC START.
Continuation:
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 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.
Reaction: Alarm display.
Remedy: Use coupling type VV and safeguard SPCOF for master and following spindle.
Program Clear alarm with the Delete key or NC START.
Continuation:
22020 Channel %1 block %3 spindle %2 gear step change position not reached
Parameters: %1 = Channel number
%2 = Spindle number
%3 = Block number, label
Definitions: Through the configuration of MA_GEAR_STEP_CHANGE_ENABLE[AXn] = 2, the spindle is
traversed to the position stored in MA_GEAR_STEP_CHANGE_POSITION[AXn] before the actual
gear step change. The required gear step change position has not been reached.
Reaction: Channel not ready.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Correct sequence in the PLC.
Program Clear alarm with the RESET key. Restart part program
