Type of coupling DV, AV
CAUTION
The coupling type may be changed only when the coupling is deactivated!
Activate synchronized mode COUPON, POSFS
● Activation of coupling with any angle reference between LS and FS:
–
COUPON(S2,S1)
–
COUPON(S2,S1,<POSFS>)
–
COUPON(S2)
● Activation of coupling with angular offset <
POSFS>
Position-synchronized coupling for profiled workpieces.
<POSFS>refers to the 0° position of the lead spindle in the positive direction of rotation
<POSFS> value range: 0°… 359,999°
–
COUPON(S2,S1,30)
You can use this method to change the angle offset even when the coupling is already
active.
Position the following spindle
When the synchronized spindle coupling is active, following spindles can also be positioned
within the ±180° range independently of the motion initiated by the master spindle.
Positioning SPOS
The following spindle can be interpolated with
SPOS=….
Example:
SPOS[2]=IC(-90)

Difference in speed M3 S... or M4 S...
A difference in speed results from signed superimposition of two sources of speed and is
programmed again for the following spindle e.g. with
S<n>=... or M<n>=3, M<n>=4 in the speed
control mode during an active synchronized spindle coupling. During the process, this speed
component is derived from the main spindle using the coupling factor and the following
spindle added to this with the correct prefix.
Note
When the direction of rotation is
M3 or M4, the speed S... also has to be reprogrammed
because otherwise an alarm is triggered to report missing programming.
