Automatic selection with COUPON and COUPONC
Depending on the coupling type, the effect of COUPON and COUPONC on the position control
for synchronous operation is as follows:
Coupling type
Following spindle FS
Leading spindle LS
The position control is activated by a COUPON and COUPONC instruction if at least one
1
following spindle has been coupled to it with coupling type DV.
Automatic deselection with COUPOF and COUPOFS
Depending on the coupling type, the effect of COUPOF and COUPOFS on the position control
is as follows:
Coupling type
Following spindle FS
Leading spindle LS
COUPOF and COUPOFS without position specification
2
Speed control mode is activated for the following spindle. Positioning mode is activated with
COUPFS with a stop position. Position control is not deactivated if the following spindle was
located in position-controlled spindle mode using SPCON or COUPFS was programmed with
position.
With COUPOF position control is deactivated if there are no more couplings of the DV
3
coupling type for this leading spindle. Position control is retained if the leading spindle is in
positioning mode or axial mode or was in position-controlled spindle mode using SPCON.
