2.1.1 SINUMERIK 810T operator interface with integrated machine control panel

When you operate the ºFeed startº key:

·the feedrate reaches the value specified in the part program

The following values are specified in machine data: - feedrate and rapid traverse speeds

- the values for the feedrate overrides

-whether the feedrate override switch is also active for rapid traverse.

Direction keys / Jogging

+X +Q

This key pad enables you to jog the

axes in the ºJOGº , ºREPOSº or ºINC...º modes.

± Q ± X

The ºFeed stopº LED must not be bright

The CRT shows you the specified feedrate value ºFº at which the axes will travel when you operate the direction keys. The value is displayed as an absolute value, and as a º%º of the programmed feedrate ºFº (see: ºFeedrate decrease / increaseº in this Section)

·You can traverse up to 2 axes simultaneously

·In ºJOGº the feed motion is arbitrary. The traverse path is only limited by the end limit switch

·In ºREPOSº the feed motion is arbitrary (see ºJOGº).

If, however, the point of interruption (in a part program that has been partially run) is reached first, the direction keys become inactive.

·The direction keys can traverse the axes:

-in continuous mode

-in jog mode.
