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-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
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-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
16751 Channel %1 block %2 spindle/axis %3 SPCOF not executable
Parameters: %1 = channel number
%2 = block number, label
%3 = axis name, spindle number
Definitions: For the programmed function, the spindle must be in the open-loop control mode.
In the positioning or axis mode, the position control must not be
deselected.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Put the spindle into open-loop control mode in the preceding block.
This can be done with M3, M4 or M5 for the relevant spindle.
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
16755 Channel %1 block %2 no stop required
Parameters: %1 = channel number
%2 = block number, label
Definitions: No Stop is needed for the programmed function. A Stop is necessary after SPOSA or after M5 if the
next block is to be applied only after the spindle has come to a stop.
Reaction: Correction block is reorganized.
Interface signals are set.
Alarm display.
Remedy: Do not write instruction.
Program Con-
tinuation:
Clear alarm with NC START or RESET key and continue the program.
