Motion Synchronous Action: Illegal Axis Type; Axis %2 Command Axis Cannot Be Started As It Is Controlled By The Plc; Block %2 Motion Synch Action: System Variable Access Not Possible; Block %2 Motion Synchronous Action: Arithmetic Error - Siemens Sinamics S120 Diagnostic Manual

20141 [Channel %1: ] Motion synchronous action: illegal axis type
Parameters: %1 = Channel number
Definitions: The requested command is not permissible in the current axis status for the command axis or spindle. This alarm
occurs with command axes (POS, MOV), spindle commands from motion synchronous actions (M3/M4/M5, SPOS),
coupled motion (TRAILON, TRAILOF) and lead value coupling (LEADON, LEADOF).
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: First stop the axis or deactivate the coupling, then select a new status.
Program Clear alarm with the RESET key. Restart part program
Continuation:
20143 [Channel %1: ] Axis %2 command axis cannot be started as it is controlled by the PLC
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: An attempt has been made to start a command axis by means of a block-related or modal synchronous action. This
start is not possible as the axis is controlled by the PLC.
Reaction: Alarm display.
Remedy: End control of the axis by the PLC and therefore return it to the channel or start the command axis with a static syn-
chronous action.
Program Clear alarm with the Delete key or NC START.
Continuation:
20144 [Channel %1: ] Block %2 motion synchronous action: system variable access not
possible
Parameters: %1 = Channel number
%2 = Block number
Definitions: When using system variables, it is assumed that a read/write operation can access the required data successfully. In
accesses to encoder actual values or digital I/Os, the result depends on the availability of the corresponding hardware
components. If an access within synchronized actions does not return a valid value, alarm 20144 is output. Outside
synchronized actions, such a read/write access causes block execution to be interrupted until the result is available.
Block execution is subsequently continued.
Reaction: NC Start disable in this channel.
Interface signals are set.
Alarm display.
NC Stop on alarm.
Remedy: Before reading/writing system variables, ensure that it is possible to access the required hardware components.
Program Clear alarm with the RESET key. Restart part program
Continuation:
20145 [Channel %1: ] Block %2 motion synchronous action: arithmetic error
Parameters: %1 = Channel number
%2 = Block number
Definitions: In calculating an arithmetic expression for a motion synchronous action, an overflow has occurred (e.g. division by
zero).
