Starting a selected curve with coupling movement (C3_CamIn)
In this chapter you can read about:
Quadratic coupling (CouplingMode = 1) .......................................................................... 251
Direct coupling (CouplingMode = 0) ................................................................................ 253
Change-over (CouplingMode = 2) ................................................................................... 254
FB name C3_CamIn
Synchronization of the axis to the output of the curve generator with adjustable coupling
movement
VAR_IN_OUT
Master
INT Axis ID; constant: AXIS_REF_LocalCam
Slave
INT
VAR_INPUT
Execute
BOOL Curve start with positive edge
CouplingMode
INT
0 = coupling without coupling movement, after the
master having traveled over the coupling position (ME)
in positive direction.
1 = coupling via quadratic function;
the master coupling position (ME) is calculated.
2 = couling via changeover function.
CouplingPosition
REAL
Master coupling position (ME) in master units
(is taken into consideration with CouplingMode = 0 and
2
with CouplingMode = 1, the coupling position is
calculated)
Value range: 0 ... n*MT
SyncPosition
REAL
Master synchronous position (MS) in master units
(not relevant with CouplingMode = 0)
Value range:
CouplingMode 1: 0 ... MT
CouplingMode 2: 0 ... n*MT
VAR_OUTPUT
InSync
BOOL Synchronous operation active
CommandAborted
BOOL Command aborted
Error
BOOL
Command aborted
Error in the cam operation
EndOfProfile
BOOL
End of a slave cam cycle.
A pulse with the length of a IEC cycle indicates the end
of each master cam cycle .
Suitable for setting up a loop counter.
