11.90 2 Operation
2.1.2 SINUMERIK 810M 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 hold” LED
must not be bright
• The CRT shows 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
(see Section 2.1.1.6: ”Feedrate decrease / increase”,
in this section)
• 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
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 µm, 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.
