Synchronized position of the following axis when switching on (CPFPOS+CPON)

When switching on the coupling (CPON) approach of the following axis can be programmed for
a specified synchronized position.
The synchronized position takes immediate effect at switch on. The total position, resulting
from the synchronized position and the coupling rule, is approached according to the specified
synchronization mode (CPFMSON), taking into account the dynamic response limits.

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 519)").
● CPFPOS without switch-on command results in an alarm.

Comment
; Block change during processing of the part program is
done with setpoint synchronism (with active coupling to
following axis X2).
CPON=FAx CPFPOS[FAx]= <value>
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 positions within the traverse range boundaries
Comment
; Activation of coupling to following axis X2. 100 is
taken as synchronized position of following axis X2.
