controlling a Sinamic G150 with S7 1200

AutoGen_5759983 Posts: 2 Rating: (0)	Greetings, i want to control the speed of my motor with a simatic s7 1200. I have added the CPU (with a PROFIBUS communication modul) and the CU 320-2 DP in the hardwareconfiguration and established a PROFIBUS-connection. What i would like to know is, how I have to program my CPU in order to send the speed values i want and to receive current values with Profibus. I tried to find information on that topic in the internet already but with little success. I would be really grateful if someone could help me with this problem. Thanks

You can choose different "telegrams", e.g. telegram1 is the simplest. The CU manual descript the meaning of each bit in the telegram, but e.g. telegram 1 has always same meaning: 1 control word, 1 speed reference 1 status word, 1 current value. you can manually set the bit/word values (e.g. control word = 47F = RUN, 47E = STOP, HEX 400 = 100% of speed) or use some ready for use block to do it for you (like SINA_SPEED). A good example (for G drives) is available in SINAMICS G: Controlling a speed axis with the “SINA_SPEED” block
