Hello. First I suggest you to read the manualof Simoreg. Connector is an analog signal, binector is digital (boolean)signal (may have values only 0 or 1). |

I don't know Simatic S7. In PLC you should create telegram with drive (send and receive) according to PPO type that you choose. In telegram to the drive first word must be control word, in which the 10th bit must be always set to 1, this signals to the drive that it will be controlled by PLC. Then connect your PLC control word in the drive using P648=K3001 or K8001. Second word of telegram to the drive is usually the speed setpoint, you must connect it to main setpoint channel. |

Thanks for your guide! I created a telegram in PLC use PPO type 2 . I can understand how to send control word to simoreg . But i still don't know how to connect the speed setpoint to main setpoint channel ?. How can i do? Thanks for your help very much! |

If you send your setpoint as second word in telegram from PLC, then in your case connect it to the P644=K3002 or K8002. |

KSN, Can i see the contactor similar to the memory of simoreg? Because i still don't undestand how can we set a value to the simoreg . If i want to set the setpoint, I must set the parameter P644=K3002 (this is the second in my program) . But, what is the value of the contactor now? . Ps: if my question so stupid, please help me step by step, because i really don't understand how a simoreg store a value ! Thankyou very much! |

What do you mean when wrote about contactor? Ok. Previously you wrote that you understand how to send control word to simoreg. This is the first word of PZD part of your telegram to the drive. Now the the next word of your telegram must be a speed setpoint. I think you have 1 CBP2, so it is 1st CBP in the drive. If you have no problem with connecting control word inside the drive, it should be P648=K3001 (see page Z110 and G180 of function diagram). In this case, next wordin telegram to the drive is your speed setpoint (K3002), you may connect it to the main setpoint channel P644=K3002 (see page Z110 and G135). Now when you set the second word of telegram in the PLC e.g. to 4000H, you can see your setpoint via parameter n733.02 and in parameter r029 (you must see 100%). |

Thank you very much KSN ! So, if i i want my "setpoint" is 2000 rev/minute, i will set my setpoint is : 4000H . How about another value? If i want my "setpoint" is 1000rev/minute, what value i will set to setpoint? How can we change between "setpoint" and "hex number"? Thanks for yourenthusiasm ! |

The value of your speed setpoint depends on the actual speed value selected in P083. Whatdo you use as actual speed now? E.g. if you use pulse encoder (P083=2) and set P143=2000 (here must be the nominal speed of motor), so the actual speed in simoreg (K040 and K067) will be 100% (or 4000H) when drive run at 2000 rev/min. So if you want your drive to run at 2000 rev/min you must set your setpoint to the value 100% (4000H or 16384) in the PLC. |
