Hello guys 

Please can any one help me for make communication between 
CPU313C-2DP and SIMOREG 6RA7*. I couldn't start and stop the drive 
through Profbus, I make hardware configuration in Step 7 and download
 this program to CPU and no error ,I can get feedback from the drive 
( SIMOREG ) PIW256 statue word 1 and PIW258 speed feedback , 
I transfer 9C7F to PQW256 to start and 9C7E to stop 
( start PQW256= 9C7F, stop PQW256=9C7E ) .
 I energize terminal 37 and 38 .
also set in the drive ( SIMOREG ) P433.01 =3002 , P648=3001 
I sent 50% to speed set point (PQW258) and start but the drive not move

I don't know what is my mistake and I don't know why the motor
 not move From the Bus

The parameters which I have already set I SIMOREG you can see it 
in attach file in my massage

1- Motor parameters 
P100 . . . Rated armature current (in amps)………….. 33.7
P101 . . . Rated armature voltage (in volts)…………….. 400
P102 . . . Rated field current (in amps)…………………. 0, 85
P104 . . . Speed n1 (in rpm) ……………………………… 2400
P105 . . . Armature current I1 (in amperes) ……………….0,1.
P106 . . . Speed n2 (in rpm) ………………………5000
P107 . . . Armature current I2 (in amperes)………………….0.1 
P108 . . . Maximum operating speed n3 (in rpm)………………..5000 
P109 . . . 1 = speed-dependent current limitation active ……………..0 

P114 . . . Thermal time constant of motor (in minutes) ………………. 10.0

P741 ……………………….. 100.0

And with this massage upload file from the drive (SIMOREG) 
and step file project which I make control to SIMOREG sent control word
 and set point, please check this two files.

Thank you for your replay

Hello Lotfi,

Did you check what I have already answered to your question: communiction between SIMOREG and S7 313C_2DP . And did you read carefully SIMOREG DC Master 6RA70 ?

regards

Thank you for your replay , yes I checked what you told me and I set that prametres to control via profibus P648 ,P433 and I cheched the terminal 37,38 and it is ok .
