Speed override  In the parameter object CfgPlcOverrideS, create a parameter set for each
spindle to which a spindle speed override is to apply.
 With MP_sourceOverride define which potentiometer is to be effective
during thread cutting for speed and feed rate

Override
potentiometer
during thread
cutting
The potentiometer adjusted with MP_sourceOverride is effective during
thread cutting for shaft speed and feed rate.
Note
If you are switching from the iTNC 530:
With MP_sourceOverride = Spindle Potentiometer you define the
iTNC 530-compatible setting for the override during thread cutting. In
milling, the feed rate during thread cutting is usually controlled with the
spindle speed override.
