Hello Mr Einstein I have seen your answer about g120 and i also messaged you in private, i written to you in private to send you an attachment that contain all information and programs you need to know my problem is: We replaced a Masterdrive Simouvert with G120 vfd containing control unit cu250s-2 dp we noticed that the old vfd 'simouvert VC' use PKW to read write commands in 1900 with SFCs 14 and 15 and status words, and use PZD to send reference in PAW 1910 while the g120 has only PZD in interface configuration of starter, how possibly could share command and status in right way ------------------------------------------------------------------------------------------ |

Hello salah; Have you attempted to control your MM420 over Profibus-DP using standard PZD telegrams to read/write to the control word and speed setpoint? As you can see in the "Essentials" document proposed in an earlier post,PZD is the "normal", suggested way of writing these commands to a MM4 drive cyclically, as per Siemens. I have never attempted to use the PKW mechanism to acyclicallycontrol the drive On/Off commands or the speed setpoint, over Profibus. If you happen to find a parameter for the control word and the speed setpoint of the MM420, you probably could find a way to use the PKW mechanism to use them. Note that you cannot use "r" parameters (read-only) or USS parameters for this, only "P" parameters. Look up the MM420 parameter list manual here: https://support.industry.siemens.com/cs/ww/en/view/24525275 Hope this helps, Daniel Chartier |

HELLO, Actually i am blocked with an application that used SFC14 15 to read write Data with DP Slave, but actually it uses PKW mecanisme to change parameter exept for the set point which is use cyclic communication PZD 1 I attached the programs PLC of masterdrive Simouvert VC; you can use go directly to FB100 and DB 100 to see it uses PKW, Attachmentis_5.zip (571 Downloads) |
