Synchronization Mode (Cpfmson) - Siemens SINUMERIK 840D sl Function Manual

Example:
Programming
CPLPOS[X2,X1]=200
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).

Synchronization mode (CPFMSON)

Synchronization mode determines synchronization behavior during switch-on of the
coupling.
Programming
Syntax:
392
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 ax-
is X1 of the coupling to following axis X2.
Comment
; Activation of coupling to following axis X2.
100 is taken as synchronized position of fol-
lowing axis and 200 for leading axis X1.
; Leading axis X1 is traversed to position 280.
; The current position X1=280 is taken as
synchronized position of the leading axis. The
previously active synchronized position of the
leading axis (200) becomes ineffective.
