Overview of Alarms
NCK alarms
Program Con- Clear alarm with the Delete key or NC START.
tinuation:
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 limi-
tation 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 posi-
tions 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 Con- Clear alarm with the Delete key or NC START.
tinuation:
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 mas-
ter 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 Con- Clear alarm with the Delete key or NC START.
tinuation:
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 Con- Alarm display showing cause of alarm disappears. No further operator action necessary.
tinuation:
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
