Activating Feed-Rate Limits - HEIDENHAIN TNC 620 User Manual

Setup | Integrated functional safety (FS)

Activating feed-rate limits

Refer to your machine manual.
This function must be adapted by your machine
manufacturer.
With this function, you can prevent the SS1 reaction (safe stopping
of drives) from being triggered when the guard door is opened.
If you press the F LIMITED soft key, the control will limit the speed of
the axes and of the spindle(s) to the values defined by the machine
tool builder. The limitation depends on the safe SOM_x operating
mode selected with the aid of the keylock switch.
If SOM_1 is active, the axes and spindles are brought to a stop,
because only then will you be allowed to open the guard doors in
SOM_1.
Select the Manual operation mode
