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 coupling
3
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.

Note
One synchronous-spindle coupling can be configured for each channel.

Function
Machine axes of the synchronous-spindle coupling:
● <n> = 0: Machine axis number of the following spindle
● <n> = 1: Machine axis number of the leading spindle
Machine axis numbers in accordance with: MD20070 $MC_AXCONF_MA‐
CHAX_USED (machine axes in the channel)
Machine axis numbers == 0: No coupling configured. The following system data
is then not relevant.
Note: The machine axes configured for the synchronous-spindle coupling cannot
be changed using program commands.
