Hi,
Thanks for your help.
I have read your example of Kollmorgen AKD Servo Drive sometimes before,
but I find that 'ethercat download'  seem to make no sense,I will try TwinCAT again.
Thanks a lot.
BestWishes.

Hi,
 
Servo drives have configurable PDO: they have different PDOs for Torque, 
Velocity or Position Mode.
 
You have to setup a SDO startup list to enable the PDO before mapping them.
You can use either 'ethercat download' or TwinCAT to find the appropriate 
startup list, then you can implement it in your program in C.
 
To illustrate the procedure, you can read my example for Kollmorgen AKD Servo Drive
