Block %2 Overlaid Motion Active At Transformation Switchover; Block %2 Transformation Does Not Allow To Traverse The Pole; As From Block %2 Transformation Active: Overlaid Motion Too Great - Siemens Sinamics S120 Diagnostic Manual

NCK alarms
Program Clear alarm with the RESET key. Restart part program
Continuation:
21616 [Channel %1: ] Block %2 overlaid motion active at transformation switchover
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The overlaid motion in the BCS changes its significance because of the transformation change and can therefore lead
to undesired axis movements.
Reaction: Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Take out the overlaid movement.
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
21617 [Channel %1: ] Block %2 transformation does not allow to traverse the pole
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The preset curve passes through the pole or a forbidden area of the transformation.
Reaction: Local alarm reaction.
NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Modify the part program (if the alarm has occurred in AUTO mode).
To escape from the alarm position, transformation must be deselected (it is not enough to try a RESET if the transfor-
mation remains active when RESET is applied).
Program Clear alarm with the RESET key. Restart part program
Continuation:
21618 [Channel %1: ] As from block %2 transformation active: overlaid motion too great
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: The share of overlaid motion on the transformation-related axes is so high that the path movement planned by the
preparation no longer sufficiently corresponds to the actual ratio for the interpolation. Strategy of singularities, moni-
toring of working range limitation and dynamic Look Ahead are possibly no longer correct.
Reaction: Alarm display.
Remedy: With overlaid motion it is necessary to keep a sufficiently large path safety distance with regard to poles and working
range limitations.
Program Clear alarm with the Delete key or NC START.
