Explanation
Assignment of the digital input for querying the external control
voltage (e.g. for the machine to be controlled)
Default value: Not connected
Assignment of the digital input for querying whether an external-
ly connected emergency stop switch was activated
Default value: Not connected
Assignment of the digital input for a push button that activates
rapid traverse. The rapid traverse is active as long as the push
button is pressed and held.
If rapid traverse is activated, feed rate limitation is ignored by the
feed rate override and the axes traverse at maximum feed rate.
Default value: Not connected
Assignment of the digital input for a push button with the follow-
ing effect:
Manual operation: Pressing the button activates the
automatic feed rate during axis movements that are
controlled via the jog buttons. The axis continues to move
until it reaches its next limit switch or until the push button
is pressed again. The automatic feed rate only functions for
axes for which limit switches have been configured
MDI mode and Program Run: the push button functions as an
NC-START key. Pressing the push button starts and interrupts
the cycles of a program block
Default value: Not connected
If no digital input is assigned to the Automatic feed
parameter, the NC-START key will be displayed during
the execution of an MDI block or a program.
Assignment of the digital input to select a smoother feed if the
entire input voltage range is used
Default value: Not connected
Assignment of the digital input to execute manual NC
movements that are independent of the spindle. The spindle is
standing still and the axes are moved in feed mode mm/min
Default value: Not connected
Spindle-independent manual movements are only
possible if there is a high level at the input.
