9.5.2 Coupled motion of punch and die
Function
Using the standard function "Coupled motion", it is possible to assign the axis of the die as a
coupled motion axis to the rotary axis of the punch.
Activation
The "Coupled motion" function is activated or deactivated with language commands TRAILON
and
TRAILOF respectively.

Example
Example of a typical nibbling machine with rotatable punches where C is the punch axis and
C1 the die axis:
Program code Comment
:
:
TRAILON (C1, C, 1) ; Enabling the coupled-motion grouping
G01 X100 Y100 C0 PON ; Initiate stroke with C axis /
; C1 axis position C=0=C1
X150 C45 ; Initiate stroke with C axis /
; C1 axis position C=45=C1

Basic position
No coupled-motion groupings are active after power up. Once the two tool axes have
approached the reference point, the coupled-motion grouping is not generally separated
again.
This can be achieved by:
● Program single activation of the coupled-motion grouping (see example above)
● Program MD setting:
MD20110 $MC_RESET_MODE_MASK, bit 8=1
In this way, the coupled-motion grouping remains active after RESET/part program start or
end.
