20065 Channel %1 master spindle not defined for geometry axes in JOG mode
Parameters: %1 = Channel number
Definitions: The displayed axis is to be traversed as geometry axis in JOG mode with rotary feed, but no master
spindle has been defined from which the actual speed could be derived.
Reaction: Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: If the revolutional feed is also to be active in JOG mode, then a master spindle must be declared via
the channel-specific machine data 20090 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 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 Clear alarm with the Delete key or NC START.
Continuation:
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.
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
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.
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.
