Hello Mr . I replaced the VLT 5000 via FC302 MCA101.are this OK or not . I did the following . add the GSD file then I used the PPO 1 the same DP ID in old version .it's show online. The frequency inverter start/stop via PLC .Still acult speed not go to PLC. I think setpoin go to FQ. due to now it work only 22.9hZ. Please help me for get the AV of speed. Please see the attachment Best regards 00967730520229. ------------------------------------------------------------------------------------------ Attachmentsami.zip (294 Downloads) |

Hello ENG YCS; How have you setup the main reference value (MRV) of your Profibus telegram? You should look at the Danfoss manual for the MCA 101 Profibus communication: files.danfoss.com › DrivesPDF Siemens S7 PLC and FC 300 Profibus - Danfoss See the screeshot below: remember that he speed reference is a percentage of the parameterized maximum speed on the drive, as per the table shown. Hope this helps, |

Hello Eng YCS: Have you selected PPO6 as Word consistent or Module consistent? Word consistent would make each section of the telegram addressable individually, Module consistent means you must use a specialized function SFC 15 (DPWR_DAT) and SFC 14 (DPRD_DAT) to monitor or write the complete telegram as a single unit. Word consistent is easier to handle fror a beginner S7 programmer. Look at the following page from the Danfoss FC300 Profibus manual I have suggested ear;ier, it describes how to select and address a PPO6 telegram. http://files.danfoss.com/download/Drives/MG37G202.pdf Notice that the address you select must match a drive parameter 9-18 Node address. And the selected address (generally above 256 for a S7-300 PLC) is a Peripheral Address, not part of the PLC's image table. Therefore to read or write, you must use peripheral addressing, for example PIW 256, PQW 256 (instead of IW/QW256). Hope this helps, Daniel Chartiier |

Hello ENG YCS; As far as the 4AX/2AX areas are concerned: You are comparing 2 different telegrams, PPO1 and PPO6. Look at the word document below. Both use 12 bytes (6 words) to transfer data to the drive, but: - PPO1 uses the 4 first words to read/write (4AX, 4 analog in/Out) to the parameters of the drive, this is called the PCV zone in Danfoss parlance.next you have a separate area 2AX for the control word and speed reference (CTW/REF). -PPO6 has no parameter zone (no PCV), so it has only one PCD zone; no need for a description of different areas, such as you have in PPO1. The PCD zone starts with 2 words (CTW/REF) and adds 4 words of process data (PCD2 to PCD5). Again I can only suggest you read up on the FC300 manual suggested in an earlier post so ypu can get you head around the drive telegram concepts, and practice starting and stopping the drive (using the CTW) and changing its speed and rotation direction (using the REF). Hope this helps, Daniel Chartier AttachmentFC302 PPO6.docx (327 Downloads) |

Hi Dear . I replaced the PPO type 1 to PP0 type 6.and made some changed in the device specific parameters. 1-auto configuration from disable to enable 2-P915/2 from none .To torque limit motor mode. 3-P915/3 From none to ramp 1 ramp up time. Then download HW configuration only to CPU . no profibus error the three FC302 show online in HW. but no data send /received between PLC master and FC302. Then return the PPO type 1 .the communication it OK and the FQ can run from panel .In auto mode only master not received the acult speed value. Please see the PDF if necessary changes the program . Best regards . AttachmentFC170.pdf (308 Downloads) |
