Basic function
Possible bit combinations p5310:
Bit 1, 0
= 0, 0 --> Function not active.
= 0, 1 --> Cyclic calculation of the coefficients without moment of inertia precontrol (commissioning).
= 1, 0 --> Moment of inertia precontrol activated (without cyclic calculation of the coefficients).
= 1, 1 --> Moment of inertia precontrol activated (with cyclic calculation of the coefficients).

<2>
<2> p1564, p5314 and p5315 for negative direction of rotation.
