CPON=X2 CPFPOS[X2]=100
Constraints
• 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 (refer to " Position
of the following axis when switching off (CPFPOS+CPOF) [Page 298] ").
• 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).

Coupling Following Position
Defines the synchronized position of the following axis when switching
on. AC, IC and GP are possible in position specification.
Type: REAL
Range of values: All position within the traverse range boundaries
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
synchronized position of the following axis. The
previously active synchronized position 100
becomes effective.
