2.3 Master value coupling
2.3.2 Programming a master value coupling
Definition and activation
A master value coupling is defined and activated simultaneously with the modal language
command for:
• Axis master value coupling
54
LEADON(FA, LA, CTABn)
– FA=following axis, as GEO axis name, channel or machine axis name (X,Y,Z,...).
– LA=leading axis, as GEO axis name, channel or machine axis name (X,Y,Z,...).
Software axis is possible:
MD30130 $MA_CTRLOUT_TYPE[n] (setpoint output type)
– CTABn=number of the curve table 1 to 999
Example: LEADON(Y,X,1) FA=Y, LA=X, curve number=1
A REF. POINT is not required to activate the coupling. A defined FA cannot be traversed
in JOG mode (not even if the synchronism FINE/COARSE interface signals are not yet
present). An activated coupling must first be deactivated with LEADOF before it can be
activated again with LEADON, or else note:
MD20112 MC_START_MODE_MASK (definition of initial control system settings with NC-
START)
MD20110 $MC_RESET_MODE_MASK (definition of initial control settings after
RESET/TP-End)
Error message: 16792 "Too many couplings for axis/spindle"
Special functions: Axis Couplings and ESR (M3)
