Use the two data words to position the 2 masks "Enable fast inputs" to any
place in the process image.

Effect in the NC: The corresponding inputs are made available to the NC as
Q bits.

Example: see "Enable of fast inputs"

Use the two data words to position the 2 masks "Enable fast outputs" anyw-
here in the process image. By default, the enable of the "fast outputs" affects
the 1st digital I/O card (EC−IO).

Effect in the NC: The Q bits are transferred to the corresponding outputs.

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 manual as well as automatic operation. It can be
inhibited by M functions within a program (M48/M49 override on/off).
