Note:
If the inputs ”Mastercycle” and ”Slavecycle” are not assigned, the master cycle is
accepted by the configuration and the highest feed of the selected curve is taken
as slave cycle (see
curve types (see page 211)).
If the MasterAbsolute input stands on TRUE (absolute), the switch to the curve
genertor is closed with the CamTableSelect and the curve adapts to the master
position detection.
The MasterOffset functions as Offset for the master position acquisition;
Input not assigned means MasterOffset = 0.
If the MasterAbsolute input stands on FALSE (relative), the switch to the curve
generator is closed with the CamTableSelect and the curve does not adapt but
begins on the master side at 0.
The MasterOffset works as start delay; the curve starts only when the master has
traveled further than this value in the positive direction.
If the curve runs in single mode, only direct coupling with MC_CamIn is sensible.
If the curve runs in single mode and the master runs periodically, it is only
sensible to have the curve run relative to the master.
After running through the curve in single mode, the drive changes from the
”Synchronized Motion” state back to the ”Standstill” state, i.e. after a SingleStart a
positioning is possible.
An Execute during a curve cycle leads to a curve change at the end of the curve
cycle. The ”MasterAbsolute” and "MasterOffset" inputs are not evaluated.
Please note: If an Execute signal follows an Execute (by bouncing), another
change of curve is already triggered.
With relative master reference (MasterAbsoute=FALSE) with start delay, the
change of curve is already executed (Done=TRUE), if the master signal has not
yet reached the Masteroffset (start delay).
In the event of error message 0xFFE2: Er ror in the IEC61131-3 program
sequence. Function module was called with incorrect parameters.
