A fault is indicated for input values X>Xmax:

= HIGH
Furthermore, the output will show the y value which would result from the profile function for X=Xmax.

X

is already determined when the profile is generated (GDC).
3.2.38.1 Selection of profiles stored in the controller
Procedure
1. Inhibit the controller or set CURVEC1−X−RESET = HIGH.
)
Note!
If you have neither inhibited the controller nor set CURVEC1−X−RESET = HIGH, it is
not possible to change to another profile (error number 7;
ILLEGAL_SYSTEM_ACCESS).
2. Select the new profile (e.g. with FEVAN)
3. Wait 20 ms for data transfer
4. Initialisation starts with CURVEC1−CAM−SEL−BUSY = HIGH
5. Wait (approx. 20 ms) until CURVEC1−CAM−SEL−BUSY = LOW
6. Then CURVEC1−X−RESET = LOW.
)
Note!
Even if the controller is not inhibited, the profile can be changed with
CURVEC1−X−RESET = HIGH (e.g. via FEVAN).
During this procedure, the output CURVEC1−CAM−SEL−BUSY is HIGH.
