Siemens Sinumerik 810T - Manual (Page 35)

11.90 2 Operation
2.1.1 SINUMERIK 810T operator interface with integrated machine control panel
When you operate the ”Feed start” 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.
This key pad enables you to jog the
axes in the ”JOG” , ”REPOS” or ”INC...”
modes.
• The ”Feed stop” LED
must not be bright
• The CRT shows you the specified feedrate value
”F” at which the axes will travel when you operate
the direction keys. The value is displayed as an
absolute value, and as a ”%” of the programmed
feedrate ”F” (see: ”Feedrate decrease / increase”
in this Section)
• You can traverse up to 2 axes simultaneously
• In ”JOG” the feed motion is arbitrary. The traverse
path is only limited by the end limit switch
• In ”REPOS” the feed motion is arbitrary (see
”JOG”).
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.
