Examples:
N200 WAITC
Wait for synchronism conditions for all active slave
spindles without specification of these conditions.
N300 WAITC(S2,"FINE",S4,"COARSE")
Wait for the specified "Coarse" synchronism
conditions for slave spindles S2 and S4.
Speed ratio k

The speed ratio is defined with parameters for FS
(numerator) and LS (denominator).
Options:
•
The following and leading spindles rotate at the
same speed (n
FS

positive)
•
Rotation in the same or opposite direction (SR
T
negative) between LS and FS
•

Application: Multi-sided turning
Example
:
N… COUPDEF(S2, S1, 1.0, 4.0)
Meaning:
Following spindle S2 and leading spindle S1 rotate at
a speed ratio of 0.25.

•
The numerator must be programmed. If no
numerator is programmed, "1" is taken as the
default.
•
The speed ratio can also be changed on-the-fly,
when the coupling is active.
