Hello unique; The first download available in the following FAQ shows an example of Profibus communications to a MM4 drive with Load/Transfer instructions, without wholeconsistency (SFC15/14). In LAD you can use MOVE instructions instead of the STL instructions Load/Transfer. MICROMASTER 4 (MM4): Are there program examples for the Instruction Manual of the MICROMASTER PROFIBUS option module? |

When you use PROFIBUS, why do you transfer the setpont via analouge signal? If you use PPO3, you can simply use the MOVE command to copy the data to/from drive. The sfc14/15 make shure the data consistency is larger then 4 bytes. In the attachend extract of a PDF document, you can see how to do it. The document shows how to connect a G120C to a S7-1200, but it's the same for MM4 ! I don't know if the speed reference is P20o0 in M44 too. If you use a other SIMATIC, the conversion block (Real to INT or INT to REAL) is different. AttachmentC:\Seiten aus 56749384_SINAMICS_G120C_at_S7-1200_DOKU_v10_en.pdf (188 Downloads) |

Hi dchartier , How to providerefrence value and speed for scaling my desied frequency(Hz), like 4000hex please can you explain 4000hex=100% 2000hex=50% and so on... |
