Overview of Alarms
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 fee-
drate can then be entered in [mm/rev]. (If 0 mm/rev is set as JOG feed, the control takes
the value assigned in the axis-specific MD 32050 JOG_REV_VELO or in the case of rapid
traverse overlay 32040 JOG_REV_VELO_RAPID).
The revolutional feed in JOG mode is deactivated by changing the G function from G95 to
G94.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
20070
Channel %1 axis %2 software limit switch %3
Parameters: %1 = Channel number
%2 = Axis number
%3 = "+" or "-"
Definitions: The axis is traversed by the PLC as a concurrent positioning axis and the corresponding
software limit switch is violated for the axis. No traversing.
With an additional message to alarm 20140, the axis is traversed as a command axis.
Reactions: - Alarm display.
Remedy: Please inform the authorized personnel/service department. Specify smaller target posi-
tion. Modify MD for SW limit switch. Possibly activate another SW limit switch. Retract
axis via JOG.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
20071
Channel %1 axis %2 working area limit %3
Parameters: %1 = Channel number
%2 = Axis number
%3 = "+" or "-"
Definitions: The displayed axis is operated as a "concurrent positioning axis" and the corresponding
working area limitation active for the axis is violated. No traversing movement.
With an additional message to alarm 20140, the axis is traversed as a command axis.
Reactions: - Alarm display.
Remedy: • Specify smaller target position.
• Deactivate working area limitation.
• Set working area limitation differently.
• Retract axis with JOG.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
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.
Reactions: - Alarm display.
Remedy: Please inform the authorized personnel/service department. The FC POS-AXIS for linear
and rotary axes should be used or the axis should be declared as an indexing axis. Corre-
sponding machine data for indexing axis declaration:
Modify MD 30500: INDEX_AX_ASSIGN_POS_TAB
Modify MD 10900: INDEX_AX_LENGTH_POS_TAB_1
Modify MD 10910: INDEX_AX_POS_TAB_1
