Spindle - Siemens SINUMERIK 802D sl Programming And Operating Manual

3.4.5

2. Spindle

Function
With SINUMERIK 802D sl plus and 802D sl pro, a 2nd spindle is provided.
For these control systems, the kinematic transformation functions for grinding are possible.
These functions require a second spindle for the driven workpiece.
The main spindle is operated as a rotary axis in these functions.
Master spindle
A series of functions is associated with the master spindle that can only be used with this
spindle:
• G95
• G96, G97
• LIMS
• M3, M4, M5, S...
The master spindle is defined via configuration (machine data). Generally it is the main spin-
dle (spindle 1). A different spindle can be defined as master spindle in the program:
• SETMS(n)
Switching back can also be performed via:
• SETMS
• SETMS (1)
The definition of the master spindle changed in the program is only valid until program
end/program abort. Thereafter, the configured master spindle is again active.
Programming via spindle number
Some spindle functions can also be selected via the spindle number:
S1=..., S2=...
M1=3, M1=4, M1=5
M2=3, M2=4, M2=5
M1=40, ..., M1=45
M2=40, ..., M2=45

; Rev. feedrate
; Constant cutting rate
; upper speed limit for G96, G97
; simple specifications for direction of rotation, stop and speed
; spindle n (= 1 or 2) is the master spindle as of now.
; configured master spindle is now master spindle again
; Spindle 1 is now master spindle again.
; Spindle speed for spindle 1 or 2
; Specifications for direction of rotation, stop for
spindle 1
; Specifications for direction of rotation, stop for
spindle 2
; gear stages for spindle 1 (if available)
; gear stages for spindle 2 (if available)
; Position spindle n
; Converts spindle number n to axis identifier,
; e.g. "SP1" or "CC"
; n must be a valid spindle number (1 or 2)
; The functions of spindle identifiers SPI(n) and Sn are
identical.
