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
number of gear stages installed is configured in machine data 35092 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 Clear alarm with NC START or RESET key and continue the program.
Continuation:
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 Clear alarm with NC START or RESET key and continue the program.
Continuation:
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 Clear alarm with NC START or RESET key and continue the program.
