MicroMaster 440 is link to the MM440 manual. Function diagram 5000 (page 290) describes speed setpoint channel. Parameter P1070 is the main speed setpoint. By default, it is connected to the analog input. It can be changed to be mapped to the Profibus message frame on function diagram 2700 (page 271) Parameter r2050[0] is the control word 1. Speed setpoint can be either mapped to word 2 (16 bit setpoint) or word 2 & 3 (32 bit setpoint) if finer speed resolution is needed. Parameter P2000 is the scaling factor for speed setpoint and feedback send/received over Profibus. Commissioning wizards in Starter make most of those interconnections automatically. |

Hello, due you have a Technology CPU there are two posibilities. The 2nd is more likely: 1. Your MM is connected at the left connector. It is controlled by the PLC part and you can axxess it, like in the MM manuales described. 2. Your MM is connected at the right connector. It is controlled by the Technology part. You have to define a seed controlled axis in T-Config and use MC_Power to enableit and MC_MoveVelocity to send the setpoint. Here is the Manual and here a Getting started |

Dear syd-b, If you want to control your drive through your TP177B using PROFIBUS, I would recommed that you do the following: 1. Using WinCC Flexible create a field for your speed set value(assign for example PQW274), and another one to show the actual speed for your motor (assign for example PIW258) . 2. In your PLC program open HW config. and assign you drive to Profibus network then click on it and choose the Telegram type. ( for example choose PPO3 - Screen shot) That will grant you two words to Send and two words to Receive. 3. open your OB1 and create the simple networks showen in the screen shot. 4. Start Quick Commissioning first for your drive using BOP. 5. Set the address of your drive using DIP Switches on the PROFIBUS optional board. 6. Connect your Profibus cable. 7. Send the On command for the drive through CONTROL WORD, then Send your SetPoint. For more info. Read: Commissioning PROFIBUS optional Board. AttachmentScreenshot.zip (153 Downloads) |

Hi, I connected the MM440 to the drive port and I configure it with technological function. I called from ob1 the fb401 and fb414 but can´t make drive work. The db2 is where all data was saved from tech function. What could be the problem? Thanks. AttachmentScreenshoots.zip (101 Downloads) |

The drive will not run until the MC_Power shows a "true" at "Status" Tryto call a MC_Reset with a rising signal at "enable" to reset the TO axis. Make shure the MM440 is ready and has no fault. When you open T-Config or view the Error-ID of MC_MoveVelocity, you will see there is a fault. Try to follow this manual http://support.automation.siemens.com/WW/view/en/48358172 It is for the SINAMICS S120, but the configuration of a MM440 is very similar (due it is made with Starter too). You will have other meassage frame types and you do not need the iscochrone PROFIBUS. Can you post your project? |

Hi, I attached the project I hope you can help me. I´ve tried what you said to reset the drive but it doesn´t work. Thanks. AttachmentREDES PLC.zip (120 Downloads) |
