Axis couplings
9.5 Synchronous spindle
Following spindle (FS) and leading spindle (LS)
The coupling is uniquely defined using the axis names for the following spindle (FS) and the
leading spindle (LS). The axis names have to be programmed with every
The other coupling parameters are modal and only have to be programmed if they change.
Example:
COUPDEF(S2,S1)
Transformation ratio, TFS / TLS
The transformation ratio is specified as a speed ratio between the following spindle
(numerator) and the leading spindle (denominator). The numerator must be programmed. In
the absence of a programmed value, the denominator is set to = 1.0.
Example:
Following spindle S2 and leading spindle S1, transformation ratio = 1 / 4 = 0.25.
COUPDEF(S2,S1,1.0, 4.0)
Note
The transformation ratio can also be changed on-the-fly (when the coupling is active and the
spindles are rotating).
Block change behavior NOC, FINE, COARSE, IPOSTOP
The following abbreviated notation can be used when programming the block change
