Definition of a signed evaluation factor for the currently valid traversing
speed. The specification is made in steps of 0.1 %.
Effect in the NC: The selected value is used as factor for evaluating the cur-
rently programmed maximum speed by the rough interpolator.
The override is effective in both manual as well as automatic operation. It
can be inhibited within a program via M functions.

static
Definition of speed during modal traveling using the traverse keys. Specifi-
cation in [mm/min] as 64−bit floating point number.
Effect in the NC: The selected value is accepted at a fixed position in the para-
meter field. Every time the traverse key is actuated, the respective axis is mo-
ved modally at the speed entered.

static
Definition of increment during manual traversing in inching mode. Specifi-
cation in [mm] or [inch] as 64−Bit floating point number.
Effect in the NC: The selected value is accepted at a fixed position in the para-
meter field. Every time the traverse key is actuated, the respective axis is mo-
ved about the delta specified.
