Gear stages

Function
Up to 5 gear stages can be configured for a spindle for speed / torque adaptation. The
selection of a gear stage takes place in the program via M commands (see Section
"Miscellaneous function M"):
● M40: Automatic gear stage selection
● M41 to M45: Gear stage 1 to 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
spindle (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 End of
program/program abort. Thereafter, the configured master spindle is again active.
