Description: Displays the sampling times currently present on the drive unit.
r7901[0...63]: sampling times of hardware time slices.
r7901[64...82]: sampling times of software time slices.
r7901[x] = 0, means the following:
No methods have been registered in the time slice involved.
Note: The basis for the software time slices is T_NRK = p7901[13].
Description: Displays the number of hardware sampling times that can still be assigned.
These free sampling times can be used by OA applications such as DCC or FBLOCKS.
Note: OA: Open Architecture
Description: For the manual mode: Display of STW1 (control word 1) entered at the BOP/ IOP.
Description: For the manual mode: Display of the speed setpoint entered at the BOP/ IOP.
