Overview of Alarms
NCK alarms
Definitions: The maximum permissible value of the fine correction in an orientable toolholder is limited by the
MD20188 $MC_TOCARR_FINE_LIM_LIN for linear variables, and by the MD20190
$MC_TOCARR_FINE_LIM_ROT for rotary variables. The alarm can only occur if the SD42974
$SC_TOCARR_FINE_CORRECTION is not equal to zero.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Enter a valid fine correction value.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14155 [Channel %1: ] Block %2 invalid base frame definition for tool carrier
offset
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: If a tool carrier selection causes a change in the table offset, a valid base frame must be defined in
order to store this offset; for more information see machine data 20184
(TOCARR_BASE_FRAME_NUMBER).
Reaction: Correction block is reorganized.
Interpreter stop
Interface signals are set.
Alarm display.
Remedy: Change the NC program or machine data 20184 (TOCARR_BASE_FRAME_NUMBER).
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14156 [Channel %1: ] Toolholder selection error at reset
Parameters: %1 = Channel number
Definitions: The settings in MD20110 $MC_RESET_MODE_MASK require that an active orientable toolholder is
maintained after the reset. This is done by deselecting the old orientable toolholder and then reselect-
ing it with data that may have been modified. If an error occurs during the reselection, this alarm is
issued (as a warning) and then an attempt is made to select the orientable toolholder in the initial set-
ting. If this second attempt is successful, the reset cycle is continued without any further alarms.
Typically, the alarm only occurs when the old orientable toolholder has been selected with TCOFR,
and its axis directions have been changed in such a way before the reset that a setting suitable for the
associated frame is no longer possible. If there is another cause for the alarm, this results in an alarm
also being issued when attempting to select in the initial setting. This is then also displayed in plain
text.
Reaction: Alarm display.
Remedy: Check the program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
14157 [Channel %1: ] Block %2 illegal interpolation type with MOVT
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: Linear or spline interpolation must be active with MOVT (G0, G1, ASPLINE, BSPLINE, CSPLINE).
Reaction: Correction block is reorganized.
Interpreter stop
Interface signals are set.
Alarm display.
Remedy: Modify program.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
