Block %2 Spindle %3 Gear Stage %4 Expected; Block %2 Axis %3 Spcon Not Programmed; Block %2 Spindle/Axis %3 Spcof Not Executable - Siemens Sinamics S120 Diagnostic Manual

NCK alarms
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.
Continuation:
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 rele-
vant spindle.
