Hello ellcap; Frist, have a look at the parameters linked to gain values of the MM4 PID control (see attachment); it is taken for m the following document: MICROMASTER 4: USS:Closed-loop speed control with V/f characteristic control using PID controller operation and encoder https://support.industry.siemens.com/cs/ww/en/view/24288661 Next, look at the following tables, examining MM4 parameters that can be accessed through the PZD area: For MICROMASTER 4 and for SINAMICS G120/G120D frequency inverters, which parameters can be read-out using PZD? https://support.industry.siemens.com/cs/us/en/view/23642364 Notice that P2280 (Gain), P2285 (I constant) and P2274 (D constant) are not mentioned, so they cannot be accessed through the PZD area of the drive over Profibus-DP. So you will have to setup comms using the PKW mechanism to reach and wrtite values to these parameters. Hope this helps, Daniel Chartier |
