Siemens SINUMERIK 840D sl Function Manual page 1279

certain spindle definitions (speed or cutting speed, feedrate type) can be taken from the part
program, synchronized action and FC18 and entered in the corresponding setting data:
Bit 4 = 1
Bit 8 = 1
Bit 10 = 1
Speed default
Speed defaults from part program, FC18 or synchronized actions are written to the following
setting data from all the usual sources:
SD43200 $SA_SPIND_S (speed for spindle start via PLC interface)
The setting data can be written to as follows:
● Through speed programming
● Through direct programming in the part program
● Through HMI software
Note
The setting data is written immediately and asynchronously to part-program execution.

Function Manual, 01/2015, 6FC5397-0BP40-5BA2
The programmed speed S... including speed setpoints via FC18 and synchronized
actions are accepted in the following setting data:
SD43200 $SA_SPIND_S (speed for spindle start via PLC interface)
Programmed S values that are not programmed speed values are not accepted in the
SD. These include, for example:
● S value at constant cutting speed (G96, G961)
● S value for rotation-related dwell time (G4)
The programmed cutting speed S... including setpoints via FC18 and synchronized
actions are accepted in the following setting data:
SD43202 $SA_SPIND_CONSTCUT_S (cutting speed for spindle start via PLC inter‐
face)
Programmed S values that are not programmed cutting speed values are not accepted
in the SD. These include, for example:
● S value outside the constant cutting speed (G96, G961, G962)
● S value for rotation-related dwell time (G4)
For the master spindle, the value of the 15th G group (feedrate type) is accepted in the
following setting data SD43206 $SA_SPIND_SPEED_TYPE.
SD43206 $SA_SPIND_SPEED_TYPE (spindle speed type for spindle start via PLC
interface)
For all other spindles, the value in SD43206 remains unchanged.
