Hola carioca; The Profibus-DP module for the midimaster is the CB15. Here you will find the manual for this module, including explabations on the control word and the speed reference word. http://support.automation.siemens.com/WW/view/en/7052355 Look at chapter 5, Commissioning, to see how both words can be ussed. Notice especially the note on page 26 that give an example of starting the drive from the control word: first write the value hex(047E) to the control word address (this will be given to you when you configure the drive asa Profibus slave in the HWConfiog editor of Step 7), then write hex(047F). The change from E top F in the last part of the control word acts as a rising edge on bit 0, and this is what the drive expects to start. The speed reference word is simple to control, if you understand how it is built. A maximum speed value has to be set in the drive's parameters (P904). Then, writing hex(4000) to the speed reference word addresscommands the drive to run to that speed once the start command is given; hex(2000) imposes 50% oif the max speed; hex(1000) means 25%..... with all possible combinations in between. The Midimaster interface uses Profibus in exactly the same way as the Micromaster. You can search the forum for Micromaster Profibus-DP connections, many threads have been started on the subject, and they could help you out. Hope this helps, Daniel Chartier |
