Spindles in master value coupling
A spindle can only be used as the master value coupled following axis if it has been switched
to axis mode beforehand. The machine data parameter block of the axis drive then applies.
Example: Activation from synchronized action
Program code
SPOS=0
B=IC(0)
RELEASE(Y)
ID=1 WHEN ($AA_IM[X]<-50) DO LEADON(B,X,2)

Definition and activation
An axis master value coupling is defined and activated simultaneously with the modal
effective language command LEADON.
Syntax:
LEADON(<FA>,<LA>,<CTABn>)
Meaning:
<FA>
<LA>
<CTABn>
Example:
Program code
LEADON(Y,X,1)
