13.2.4 Automatic selection and deselection of position control
Behavior in speed control mode
In DV coupling mode, program instructions COUPON, COUPONC and COUPOF, COUPOFS are used to
activate and/or deactivate position control for the leading spindle as required. If there are
several following spindles on the leading spindle, then in speed-controlled mode, the first
DV activates coupling position control for the leading spindle and the last DV coupling
deactivates coupling position control for the leading spindle if SPCON is not programmed.
The leading spindle does not need to be located in the same channel as the following
spindle.
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 DV AV VV
Following spindle FS Position control ON Position control ON No action
Leading spindle LS Position control On
1
No action No action
1
The position control is activated by a COUPON and COUPONC instruction if at least one
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 DV AV VV
Following spindle FS Position control OFF
2
Position control OFF
2
No action
2
Leading spindle LS Position control OFF
3
No action No action
2
COUPOF and COUPOFS without position specification
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.
3
With COUPOF position control is deactivated if there are no more couplings of the DV
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.
