3. Configuring the NCK
Before configuring the expanded message frames, you first need to perform the
standard configuration on the NCK for the drive.
How to proceed with the standard configuration of a drive is described in Sec-
tion 11.5.3, Page 11-314.
Perform the following actions to transfer the additional PDA to the general
system variables:
1. Select the option: ”Evaluation of internal drive variables”.
2. Activate the transfer to general system variable:

message frame for the cyclic communication of the drive is only explicitly visible
in the following machine data:
