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

Example:
Programming
CPON=X2 CPFPOS[X2]=100
Supplementary conditions
● CPFPOS is only effective as synchronized position with the switch-on command CPON/
CPLON.
The switch-off command CPOF evaluates CPFPOS as switch off position (see Section
"Following Axis Position on Switch off (Page 396)").
● CPFPOS without switch-on command results in an alarm.
● If the synchronized position of the following axis is not set during switch on, then the current
position of the following axis takes effect as synchronized position.
The program instruction IC can be used to move the current position.
● The position specification is specified in the configured basic system independently of the
programmable dimensions(G70/G71).

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.

Comment
; Activation of coupling to following axis X2. 100 is
taken as synchronized position of following axis X2.
Comment
; Activation of coupling to following axis X2. 100
is taken as synchronized position of the following
axis.
; Following axis X2 is traversed to position 123.
; The current position (=123) is taken as synchron-
ized position of the following axis. The previous-
ly active synchronized position 100 becomes effec-
tive.
