SD43300 and SD42600
The revolutional feedrate behaviour can be selected externally via the axial setting data:
SD43300 $SA_ASSIGN_FEED_PER_REV_SOURCE (Rotational feedrate for spindles)
in JOG operating mode using the channel-specific setting data
SD42600 $SC_JOG_FEED_PER_REV_SOURCE (Revolutional fedrate control in JOG mode)
.
The following settings can be made via the setting data:
>0:
-1:
