3. Configuring the NC
Before configuring the expanded message frame configuration, you first need to perform the
standard configuration on the NC for the drive.
Standard configuration
How to proceed with the standard configuration of a drive is described in Subsection "Drive
configuration" (Page 389).
Expanded message frame configuration
Perform the following actions to transfer the additional PDA to the general system variables:
1.
Activate the option “Evaluation of internal drive variables”.
2. Activate the transfer to general system variable:
● MD36730 $MA_DRIVE_SIGNAL_TRACKING[n] = 2
Note
After configuring the expanded message frames, the original configured message frame
for the cyclic communication of the drive is only explicitly visible in the following machine
data:
•
MD13060 $MN_DRIVE_TELEGRAM_TYP[n] (drive message frame type)
18.2.5 Project design: SIMODRIVE
The extended message frame configuration with reference to the following drives is
illustrated on the basis of an example using SIMODRIVE 611 universal (DP slave 611U).
●
SIMODRIVE 611 universal or universal E
● SIMODRIVE POSMO CD/CA
● SIMODRIVE POSMO SI
Please adapt your procedure for the other SIMODRIVE drives.
Standard engineering
Before performing the expanded message frame configuration, please define the following:
●
The standard message frame that is to be used for the DP slave drive.
● How many drive actual values/PDA are also to be transferred
Note
It is advisable to configure each component first with the standard message frame and
then expand the frame by the additional PDA.
