Synchronized Position Of The Leading Axis When Switching On (Cplpos) - Siemens SINUMERIK 840D sl Function Manual

5.5.5.6

Synchronized position of the leading axis when switching on (CPLPOS)

The current leading axis position, taken as leading value, can be offset. The synchronized
position of the leading axis therefore defines the zero point of the input variable.

Constraints
• CPFPOS can only set with the switch-on command CPON / CPLON. CPFPOS without switch-
on command results in an alarm.
• If the synchronized position of the leading axis is not set with the switch on command
(CPON), then the current position of the leading axis takes effect as synchronized position
and therefore as zero point of the input variable.
• The position specification is specified in the configured basic system independently of the
programmable dimensions(G70 / G71).

Coupling Lead Position
Defines the synchronized position of the following axis at switch on.
Only AC is possible in the position specification.
Type: REAL
Range of values: All position within the traverse range boundaries
Comment
; 200 is taken as synchronized position of the leading
axis X1 of the coupling to following axis X2.
Comment
; Activation of coupling to following axis X2.
100 is taken as synchronized position of
following axis and 200 for leading axis X1.
