Axis %2 Software Limit Switch %3 Programmed End Position %4; Axis %2 Working Area Limit %3 End Position %4; Axis %2 Is Not An Indexing Axis - Siemens Sinamics S120 Diagnostic Manual

Reaction: Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: If the revolutional feedrate is to be active in JOG mode too, then a master spindle must be declared in the channel-
specific machine data MD20090 $MC_SPIND_DEF_MASTER_SPIND. In this case, you have to open a screen in the
PARAMETER operating area with the softkeys "SETTINGDATA" and "JOG DATA", and preselect the G function G95
there. The JOG feedrate can then be entered in [mm/rev]. (If 0 mm/rev is set as JOG feedrate, the control takes the
value assigned in the axis-specific machine data MD32050 $MA_JOG_REV_VELO or in the case of rapid traverse
override MD32040 $MA_JOG_REV_VELO_RAPID).
The revolutional feedrate in JOG mode is deactivated by changing the G function from G95 to G94.
Program Clear alarm with the Delete key or NC START.
Continuation:
20070 [Channel %1: ] Axis %2 software limit switch %3 programmed end position %4
Parameters: %1 = Channel number
%2 = Axis number
%3 = "1+" or "1-" for software limit switches 1, "2+" or "2-" for software limit switch 2,
%4 = Programmed end position
Definitions: The axis is to be traversed by the PLC as a concurrent positioning axis to the limit position. This would violate the
corresponding software limit switch for the axis. No traversing takes place.
With an additional message to alarm 20140, the axis is to be traversed as a command axis.
Reaction: Alarm display.
Remedy: Please inform the authorized personnel/service department. Specify smaller target position. Modify MD for SW limit
switch. Possibly activate another SW limit switch. Retract axis via JOG.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
20071 [Channel %1: ] Axis %2 working area limit %3 end position %4
Parameters: %1 = Channel number
%2 = Axis number
%3 = "+" or "-"
%4 = Programmed end position
Definitions: The displayed axis is to be traversed as a "concurrent positioning axis" to the programmed limit position and the cor-
responding working area limitation active for the axis is violated. No traversing takes place.
With an additional message to alarm 20140, the axis is traversed as a command axis.
Reaction: Alarm display.
Remedy: - Specify smaller target position.
- Deactivate working area limitation.
- Set working area limitation differently.
- Retract axis with JOG.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
20072 [Channel %1: ] Axis %2 is not an indexing axis
Parameters: %1 = Channel number
%2 = Axis number
Definitions: The displayed axis is operated as a concurrent positioning axis. Its target position is parameterized in the FC INDEX-
AXIS as indexing position number, but the axis is not an indexing axis.
Reaction: Alarm display.
