Configuring the additional drive actual values
The drive utilization for PDA11 is configured via the selection list of the cor-
responding parameter (PROFIDrive parameter P0916[x]) in Fig. 16-4.

Fig. 16-4 Configuring the additional drive actual values
Before configuring the expanded message frames, you first need to perform the
standard configuration on the NC for the drive.
How to proceed with the standard configuration of a drive is described in Sec-
tion 10.5.3, page 10-313.
On the NC for the expanded message frame configuration, you only need to
activate PDA transfer in the respective system variable.

Option: “Evaluation of internal drive variables”,
Order No.: 6FC5 251-0AB17-0BA0
–
NC machine data for activating the data transfer in the system variables:
S
MD 36730: DRIVE_SIGNAL_TRACKING[n] (acquisition of additional
drive actual values)
Note
After configuring the expanded message frames, the standard message frame
with which the axis is driven is only explicitly visible in the NC machine data:
S
MD 13060: DRIVE_TELEGRAM_TYPE[n] (drive message frame type)
