Overview of Alarms
NCK alarms
16747 [Channel %1: ] Block %2 spindle %3 inserted gear stage %4 for tapping
not installed
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Spindle number
%4 = Gear stage
Definitions: The second gear stage data block has been activated for tapping with G331.
However, the current gear stage has not been installed in the second gear stage data block. The num-
ber of gear stages installed is configured in MD35092 $MA_NUM_GEAR_STEPS2. The gear stage
cannot be changed in traversing blocks. The gear stage appropriate for the speed must be loaded
before the traversing block.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Procedure for automatically engaging the suitable gear stage prior to thread cutting:
* Program the spindle speed (S) in a G331 block without axis motions and prior to thread cutting, e.g.
G331 S1000.
* Activate M40 for the spindle.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16748 [Channel %1: ] Block %2 spindle %3 gear stage %4 expected
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Spindle number
%4 = Gear stage
Definitions: G331 activates the second gear stage data block for tapping.
The programmed speed (S) of the master spindle lies outside the speed range of the active gear stage
in the current traversing block.
The gear stage cannot be changed in the traversing block. The gear stage appropriate for the speed
must be loaded prior to the traversing block.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Procedure for automatically engaging the suitable gear stage prior to thread cutting:
* Program the spindle speed (S) in a G331 block without axis motions and prior to thread cutting, e.g.
G331 S1000.
* Activate M40 for the spindle.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16750 [Channel %1: ] Block %2 axis %3 SPCON not programmed
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
Definitions: For the programmed function (rotary axis, positioning axis), the spindle must be in position control
mode.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Program position control of the spindle with SPCON in the previous block.
Program Con- Clear alarm with NC START or RESET key and continue the program.
tinuation:
16751 [Channel %1: ] Block %2 spindle/axis %3 SPCOF not executable
Parameters: %1 = Channel number
%2 = Block number, label
%3 = Axis name, spindle number
