3.5.4.2 Closed Loop function<br />
Click the Cosed Loop function.<br />
Data communication between control (TNC/NC) and encoder is picked up by a signal splitter (in<br />
the example: SA 100 Service Adapter, ID 363706-01). The encoder loop remains closed and the<br />
NC control can still traverse the machine axis.<br />
Prerequisite:<br />
"Listening in" is only possible with purely serial interfaces (EnDat 21 and 22, Fanuc, Mitsubishi,<br />
<strong>DR</strong>IVE-CLiQ). The subsequent electronics must support the diagnostic function! The diagnostic<br />
function of the subsequent electronics (TNC control) must be active!<br />
Message, if data communication fails:<br />
Message, if the test unit cannot synchronize with the data stream (diagnostic function of<br />
subsequent electronics inactive):<br />
The further procedure is similar to the open-loop measurement, see chapter “Open Loop<br />
function" on page 78.<br />
