Overview of Alarms
20058
Channel %1 axis %2 revolutional feedrate: illegal feed source
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: An axis/spindle is to be traversed at revolutional feedrate. The reference axis/spindle
defined in SD 43300 ASSIGN_FEED_PER_REV_SOURCE refers to itself. The coupling
caused cannot be executed.
Reactions: - Alarm display.
Remedy: The reference axis/spindle must be modified accordingly in SD 43300.
Program Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
20059
Channel %1 axis %2 already active due to %3
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Cause
Definitions: The axis (machine axis, geometry axis or orientation axis) is to be traversed in operation
mode "Automatic&Jog" (see $MN_JOG_MODE_MASK) by using the direction keys or a
handwheel. This is not possible, as (see parameter 3):
1. the axis is active as a rotating spindle
2. the axis is a PLC axis
3. the axis is active as an asynchronous reciprocating axis
4. the axis is active as a command axis
5. the axis is active as a slave axis
6. a frame applies for a rotated coordinate system and an axis involved in the required
JOG movement of the geometry axis is not available for this
7. an axis container rotation is activated via NCU link
Note: This alarm identifies an axis not capable of JOG which received a JOG order. In this
case, the NCK will not proceed according to "Internal JOG".
Reactions: - Alarm display.
Remedy: Wait for the axis to traverse or abort with distance-to-go delete or RESET.
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
20060
Channel %1 axis %2 cannot be traversed as geometry axis
Parameters: %1 = Channel number
%2 = Axis name
Definitions: The axis is currently not in "Geometry axis" state. Therefore, it cannot be traversed in
JOG mode as geometry axis.
If the abbreviation WCS (workpiece coordinate system) is displayed in the "Position"
screen, then only the geometry axes can be traversed by means of the direction keys!
(MCS ... Machine coordinate system; all machine axes can now be traversed by using
the direction keys on the machine control panel).
Reactions: - Alarm display.
