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)

Function Manual, 06/2019, A5E47437747B AA
Following axis as geometry-, channel- or machine axis name (X, Y, Z,...)
Leading axis as geometry-, channel- or machine axis name (X, Y, Z,...)
Software axis is also possible:
MD30130 $MA_CTRLOUT_TYPE=0 (setpoint output type)
Number of curve table
Value range: 1 to 999
Comment
;Definition and activation of a master value coupling between
the leading axis X and the following axis Y. Curve Table No. 1
should be used to calculate the following value.
14.3 Master value coupling
