This key pad enables you to jog the axes in the ºJOGº, ºREPOSº or ºINC...º modes.

· 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 key(s). The value is displayed as an absolute value and as a º%º of the programmed feedrate ºFº (see Section 2.1.1.6: 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 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.

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.

It is defined in machine data whether the axes are traversed using the direction keys in either:

-continuous mode or

-jog mode.
