Axis couplings
9.5 Synchronous spindle
Example 3: Examples of transfer of a movement for difference in speed
1. Activate coupling during previous programming of following spindle with COUPON
Programming
N05 M3 S100 M2=3 S2=200
N10 G4 F5
N15 COUPDEF(S2,S1,1)
N20 COUPON(S2,S1)
N10 G4 F5
2. Activate coupling during previous programming of following spindle with COUPONC
Programming
N05 M3 S100 M2=3 S2=200
N10 G4 F5
N15 COUPDEF(S2,S1,1)
N20 COUPONC(S2,S1)
N10 G4 F5
3. Activate coupling with following spindle stationary with COUPON
Programming
N05 SPOS=10 SPOS[2]=20
N15 COUPDEF(S2,S1,1)
N20 COUPON(S2,S1)
N10 G4 F1
4. Activate coupling with following spindle stationary with COUPONC
Note
Positioning or axis mode
If the following spindle is in positioning or axis mode before coupling, then the following
spindle behaves the same for COUPON(<FS>,<LS>) and COUPONC(<FS>,<LS>).

Comment
; Leading spindle = master spindle = spindle 1
; Following spindle = spindle 2
; Leading spindle rotates at 100 rpm, following spindle at 200 rpm.
; Dwell time = 5 seconds of master spindle
; Transformation ratio of FS to LS is 1.0 (default).
; On-the-fly coupling to the leading spindle.
; Following spindle rotates at 100 rpm.

; Leading spindle rotates at 100 rpm, following spindle at 200 rpm.
; Dwell time = 5 seconds of master spindle
; Transformation ratio of FS to LS is 1.0 (default).
; On-the-fly coupling to leading spindle and transfer previous speed
to S2.
; S2 rotates at 100 rpm + 200 rpm = 300 rpm
Comment
; Leading spindle = master spindle = spindle 1
; Following spindle = spindle 2
; Following spindle S2 in positioning mode.
; Transformation ratio of FS to LS is 1.0 (default).
; On-the-fly coupling to the leading spindle.
; Coupling is closed, S2 stops at 20 degrees.
