If you assign the access right Query to a connection and access is
implemented from this address, the TNC opens a pop-up window.
You must permit or deny external access in the pop-up window:
External access Permission
Yes Permit once
Always Permit continuously
Never Deny continuously
No Deny once
In the overview list an active connection is shown
with a green symbol.
Connections without access rights are shown gray in
the overview list.
Entering traverse limits
The Traverse limits function must be enabled and
adapted by the machine tool builder.
Refer to your machine manual.
The MOD function Traverse limits enables you to limit the actually
usable tool path within the maximum traverse range. This enables
you to define protection zones in each axis to protect a component
from collision for example.
To enter traverse limits:
In the MOD menu select the Machine settings group
Select the Traverse limits menu
Enter the values of the desired axes as a reference value or load
the momentary position with the
ACTUAL POSITION CAPTURE
soft key
Press the
APPLY soft key
Press the OK soft key
The protection zone becomes active automatically as
soon as you set a limit in an axis. Settings are kept
even after restarting the control.
You can only deactivate the protection zone by
deleting all values or pressing the
CLEAR ALL soft
key.
