The range of values and the functionality correspond to the 15th G group "feed type".
Permissible values are the G values: 93, 94, 95, 96, 961, 97, 971 and 973.
The stated values make a functional distinction between the following variants:
==> 93, 94, 95, 97 and 971: The spindle is started at the speed in SD 43200
$SA_SPIND_S.
==> 96 and 961: The speed of the spindle is derived from the cutting speed of SD
43202 $SA_SPIND_CONSTCUT_S and the radius of the transverse axis.
==> 973: G973 behaves like G97, but the spindle speed limitation is not active
The default value is 94 (corresponds to G94)
The default value becomes active if the SD is written with impermissible values.
43210 SPIND_MIN_VELO_G25 - S1
rev/min Programmed spindle speed limitation G25 DOUBLE Immediately
-
- - 0.0 0.0 - 7/7 U
Description: A minimum spindle speed limit below which the spindle must not fall is entered in
SPIND_MIN_VELO_G25. The NCK limits the set spindle speed to this value if it is too
low.
The spindle speed may only fall below the minimum as a result of:
● Spindle offset 0%
● M5
● S0
● NC/PLC interface signal DB380x DBX4.3 (Spindle stop)
● NC/PLC interface signal DB380x DBX2.1 (Servo enable)
● NC/PLC interface signal DB3300 DBX3.7 (Channel status: Reset)
● NC/PLC interface signal DB380x DBX2.2 (Delete distance-to-go/Spindle reset)
● NC/PLC interface signal DB380x DBX2002.5 (Oscillation speed)
● Cancel S value

43220 SPIND_MAX_VELO_G26 - S1
rev/min Programmable upper spindle speed limitation G26 DOUBLE Immediately
-
- - 1000.0 0.0 - 7/7 U
Description: A maximum spindle speed is entered in SD43220 $SA_SPIND_MAX_VELO_G26, which the
spindle must not exceed. The NCK limits an excessive spindle speed setpoint to this
value.
SD irrelevant for ......
all spindle modes except open-loop control mode.

The value in SD43210 $SA_SPIND_MIN_VELO_G26 can be altered by means of:
● G26 S.... in the part program
● Operator commands via HMI
The value in SD43210 $SA_SPIND_MIN_VELO_G26 is retained after a reset or Power Off.
