The homing has to be carried out before every sync start.
Function:
Accuracy: This parameter specifies that maximum master –
slave position deviance, this is used to control the accuracy out-
put (O 3). The accuracy output will only be "1" if the actual
master – slave position deviance is within this value. In velocity
synchronisation (par. 19-01 = 0, 3, 6 or 7) the value must be
set in RPM (Rounds Per Minute) in all other modes it must be
set in quad counts. With a negative value in this parameter the
synchronising error (par. 19-93) is shown with a sign otherwise
the synchronising error is unsigned.
Function:
M-S tolerance speed: Specify here the tolerated speed deviation
between master and slave while synchronising. The following
apply here:
Slave must catch up: The slave can travel at the maximum per-
mitted speed or at the speed: master speed + master speed *
M-S tolerance speed / 100, whichever of the two is lowest.
Slave must slow down:
The slave travels at the minimum speed:
master speed - master speed * M-S tolerance speed / 100. If
the M-S tolerance speed value is set to 50, the slave will not
travel more slowly than half the master speed.
Function:
Enter here the interval between two markers at the master drive
in quad counts. If this value is not known, it can be determined
during the test run. For procedure, see as described in the sec-
tion "Testing the incremental encoders" in the Loading belt,
Marker synchronisation, application example.
NB!
This parameter is only used in marker synchronis-
ing mode (par. 19-01 = 2 or 5).
Function:
Enter here the interval between two markers at the slave drive
in quad counts. If this value is not known, it can be determined
during the test run. For procedure, see description in the section
"Testing the incremental encoders" in the packaging application
example.
