Program Clear alarm with the Delete key or NC START.
Continuation:
20054 [Channel %1: ] Axis %2 wrong index for indexing axis in JOG mode
Parameters: %1 = Channel number
%2 = Axis name, spindle number
Definitions: 1. The displayed indexing axis is to be traversed incrementally in JOG mode (by 1 indexing position). However, no
further indexing position is available in the selected direction.
2. The axis is stationary at the last indexing position. In incremental traversing the working area limitation or the
software limit switch is reached without an indexing position being located in front of it at which a stop could be made.
Reaction: Alarm display.
Remedy: Please inform the authorized personnel/service department. Correct (add to) the list of indexing positions by means
of the machine data
MD10900 $MN_INDEX_AX_LENGTH_POS_TAB_1
MD10910 $MN_INDEX_AX_POS_TAB_1
MD10920 $MN_INDEX_AX_LENGTH_POS_TAB_2
MD10930 $MN_INDEX_AX_POS_TAB_2
or set the working area limits or the software limit switches to other values.
Program Clear alarm with the Delete key or NC START.
Continuation:
20055 [Channel %1: ] Master spindle not present in JOG mode
Parameters: %1 = Channel number
Definitions: The displayed axis is to be traversed as machine axis in JOG mode with revolutional feed, but no master spindle has
been defined from which the actual speed could have been derived.
Reaction: Local alarm reaction.
Interface signals are set.
Alarm display.
Remedy: Please inform the authorized personnel/service department.
If the revolutional feed is also to be active in JOG mode, then a master spindle must be declared via the channel-
specific 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 feed, the control takes the value assigned in the
axis-specific MD 32050 $MA_JOG_REV_VELO or in the case of rapid traverse overlay MD32040
$MA_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:
20056 [Channel %1: ] Axis %2 no revolutional feedrate possible. Axis/spindle %3 stationary
Parameters: %1 = Channel number
%2 = Axis name, spindle number
%3 = Axis name, spindle number
Definitions: An axis is to travel in JOG with revolutional feed, but the spindle/axis the feed is to be derived from is 0.
Reaction: Alarm display.
Remedy: Traverse the spindle/axis from which the feed is to be derived.
Program Alarm display showing cause of alarm disappears. No further operator action necessary.
Continuation:
20057 [Channel %1: ] Block %2 revolutional feedrate for axis/spindle %3 is <= zero
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: Revolutional feed has been programmed for an axis/spindle, but the velocity was not programmed or the programmed
value is smaller than or equal to zero.
Reaction: Correction block is reorganized.
