S 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. 18-5.

Configuring the additional drive actual values
Before configuring the extended message frames, you must first 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 11.5.3, Page 11-314.
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 number (MLFB): 6FC5 251–0AB17–0BA0
– NC machine data for activating the data transmission 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)
