Axis %2 Already Active; Axis %2 Drf, Ftocon, External Zero Point Offset Not Possible; Axis %2 Wrong Index For Indexing Axis In Jog Mode - Siemens Sinamics S120 Diagnostic Manual

Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
20052 [Channel %1: ] Axis %2 already active
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The axis is to traverse as a machine axis in JOG mode using the direction keys on the machine control panel. However,
this is not possible because:
1. It is already traversing as a geometry axis (through the channel-specific interface DB3200 DBX1000.7 / 0.6 (Tra-
versing keys -/+) or DB3200 DBX1004.7 / 4.6 (Traversing keys -/+) or DB3200 DBX1008.7 / 8.6 (Traversing keys -/+))
or
2. It is already traversing as a machine axis (through the axis-specific interface DB380x DBX0004.7 / 4.6 (Traversing
keys plus/minus)) or
3. A frame is valid for a rotated coordinate system, and another geometry axis involved in this is already traversing in
JOG mode by means of the direction keys.
Reaction: Alarm display.
Remedy: Stop traversing through the channel or axis interface or stop the other geometry axis.
Program Clear alarm with the Delete key or NC START.
Continuation:
20053 [Channel %1: ] Axis %2 DRF, FTOCON, external zero point offset not possible
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: The axis is traversed in a mode (e.g. referencing) that allows no additional overlaid interpolation.
Reaction: Alarm display.
Remedy: Wait until the axis has reached its reference position or terminate reference point approach with "Reset" and start DRF
once again.
Program Clear alarm with the Delete key or NC START.
Continuation:
20054 [Channel %1: ] Axis %2 wrong index for indexing axis in JOG mode
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: 1. The displayed indexing axis is to be traversed incrementally in JOG mode (by 1 indexing position). However, no
further indexing position is available in the selected direction.
2. The axis is stationary at the last indexing position. In incremental traversing the working area limitation or the soft-
ware limit switch is reached without an indexing position being located in front of it at which a stop could be made.
Reaction: Alarm display.
Remedy: Please inform the authorized personnel/service department. Correct (add to) the list of indexing positions by means
of the machine data
MD10900 $MN_INDEX_AX_LENGTH_POS_TAB_1
MD10910 $MN_INDEX_AX_POS_TAB_1
MD10920 $MN_INDEX_AX_LENGTH_POS_TAB_2
MD10930 $MN_INDEX_AX_POS_TAB_2
or set the working area limits or the software limit switches to other values.
Program Clear alarm with the Delete key or NC START.
