13.5 Synchronous spindle
Job planning
Programming Manual, 03/2006 Edition, 6FC5398-2BP10-1BA0
13-15
Optional parameters
LS Designation of main spindle;
Specification with spindle number: e.g. S2, S1
T
FS
, T
LS
Speed ratio parameters for FS = numerator and LS = denominator
Default setting = 1.0; specification of denominator optional
Block change
behavior:
"NOC"
"FINE"
"COARSE"
"IPOSTOP"
Block change method; Block change is implemented:
Immediately
At "Synchronism fine"
At "Synchronism coarse"
in response to IPOSTOP (e.g. after setpoint-based synchronism)
(presetting)
The block change method is modal
Coupling type
"DV"
"AV"
"VV"
Coupling type: Coupling between FS and LS
Setpoint linkage (default)
Actual value coupling
Speed coupling
The coupling type is modal.
POS
FS
Angle offset between leading and following spindles
POS
FS
, POS
LS
Switch-off positions of following and main spindles
"The block change is enabled once POS
FS
, POS
LS
has been
crossed"
Example of working with master and slave spindles.
;Leading spindle = master spindle =
;spindle 1
;Following spindle = spindle 2
N05 M3 S3000 M2=4 S2=500 ;Master spindle rotates at 3000 rpm
;following spindle at 500 rpm
N10 COUPDEF (S2, S1, 1, 1, "NOC",
"Dv")
;Def. of coupling, can also be configured
…
N70 SPCON ;Include master spindle in position control
;(setpoint coup.)
N75 SPCON(2) ;Include slave spindle in position control
N80 COUPON (S2, S1, 45) ;On-the-fly coupling to offset position =
;45 degrees
…
N200 FA [S2] = 100 ;Positioning speed = 100 degrees/min
N205 SPOS[2] = IC(-90) ;Traverse with 90° overlay in
;negative direction
N210 WAITC(S2, "Fine") ;Wait for "fine" synchronism
N212 G1 X… Y… F… ;Machining
…
N215 SPOS[2] = IC(180) ;Traverse with 180° overlay in
;positive direction
N220 G4 S50 ;Dwell time = 50 revolutions of master
;spindle
N225 FA [S2] = 0 ;Activate configured speed (MD)
N230 SPOS[2] = IC (-7200) ;20 rev. With configured speed in
;negative direction
