<1> A pair of values p8870[Index], p8872[Index] may only be used once in a device.
<2> All changes become effective with p8842 = 1. Afterwards, p8842 = 0 is automatically set.
A change can also be activated via warm restart, project download or POWER ON.
<3> The number of process data n (PZD) depends on the drive object.
