Cause : Enable signals for the rotating measurement missing comes when the rotating measurement cannot be started due to missing enable signals.

For p1959.13 = 1, the following applies:

- enable signals for the ramp-function generator missing (see p1140 ... p1142).

- enable signals for the speed controller integrator missing (see p1476, p1477).

- acknowledge faults that are present.

- establish missing enable signals.
