2Nd Spindle / Master Spindle - Siemens SINUMERIK 802D sl Function Manual

Block change with SPOS
If the spindle is being positioned with SPOS, the block change will be dependent on the end
point monitoring with the IS "Position reached with exact stop fine". All other functions
programmed in the block must have achieved their end criterion (e.g. axes ready, all
auxiliary functions acknowledged by the PLC).

Note
This function is not available for the 802D sl value.
Function
The TRANSMIT and TRACYL kinematic transformation functions are available for milling on
lathes. These functions require a second spindle for the driven milling tool. The main spindle
is operated as a rotary axis with these functions.
Master spindle
A series of functions is connected to the master spindle, which are only possible for this
spindle:
G95
G96, G97
LIMS
G33, G34, G35, G331, G332
M3, M4, M5, S...
The master spindle is defined via configuration (machine data). Generally it is the main
spindle (spindle 1).
A different spindle can be defined as master spindle in the program:
