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.
Reaction: Alarm display.
Remedy: The reference axis/spindle must be modified accordingly in SD 43300.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
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".
Reaction: Alarm display.
Remedy: Wait for the axis to traverse or abort with distance-to-go delete or RESET.
Program Clear alarm with the Delete key or NC START.
Continuation:
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).
Reaction: Alarm display.
Remedy: Check the operating steps to establish whether geometry axes really must be traversed, otherwise
switch over to the machine axes by activating the "WCS/MCS" key on the machine control panel.
Program Clear alarm with the Delete key or NC START.
