MCO 305 Design Guide
Interval Size and Interval Time (ms)
The Interval Size is derived from the number of intervals per master cycle length.
The time in (ms) for an interval is also derived from the number of intervals per master cycle length. It
should not be smaller than 30 ms. (30 to 100 ms are suitable values.) Thus, you should make changes in
Curve Data Number of Intervals in order to get a reasonable value.
Index Cards Parameters
There are index cards for the parameters Encoder, Home, Inputs/Outputs, PID-Controller, Synchronization,
and Velocity.
Below just the special features of the latter two are explained. Please read the chapter Parameter Reference
for more information about the content, units, value range and default setting, or select an input field and
press [F1].
Index Card Synchronization
Syncfactor Master and Slave
The two parameters 33-10 Syncfactor Master and 33-11 Syncfactor Slave are used to determine the MU
units in the CAM control.
Marker Distance
Enter the distance of the sensor to the processing point here; in the case of master markers in par. 33-17
and in the case of slave markers in par. 33-18.
The position of the curve where the marker is detected is calculated from the master marker position and
the marker distance. This position is shown as a green line in the curve profile and allows you to fix the
correction area. Activate
Tolerance
Tolerance window for the appearance of the Master Markers (Marker monitoring) or of the Slave Markers
(parameters 33-21 and 33-22). The tolerance window is shown as a green area in the curve profile. Activate
Master Marker or Slave Marker for this purpose.
Index Card Velocity
In addition, the maximum velocity and acceleration reached in the current application are calculated here in
qc/scan time. The display in the curve profile occurs in units. Activate
purpose.
Settings Menu
This menu offers various options and settings
depending on operating mode.
Compiler
The default values for the compiler options are set
accordingly for most applications. Thus, they do
not require too much memory and, at the same
time, they allow the necessary input to be made.
Maximum number of variables
The number of variables has a direct effect on the
amount of memory available in the option. It is im-
portant to remember that an array also occupies
the space of a variable. Increase this number if you
need more than 92 variables (incl. arrays).
