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:

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

The setting data is written immediately and asynchronously to part-program execution.

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‐

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

For all other spindles, the value in SD43206 remains unchanged.
