11.90 2 Operation
2.1.2 SINUMERIK 810T operator interface with external machine control panel
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 key(s). The value is displayed as an absolute
value and as a ”%” of the programmed feedrate ”F”
(see Section 2.1.1.6: ”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 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.
Continuous mode:
When the direction key is pressed (whether you press for a short
or long time), the axis only traverses one increment
( 1/10/100/1000/10000
µ m, depending on the setting).
Jog mode:
The axis will traverse as long as you press the direction key. Traversing stops when you
release the key. This also happens if the set increment has not been reached.
It is defined in machine data whether the axes are
traversed using the direction keys in either:
- continuous mode or
- jog mode.
