Dear ni lar, We should consider different possibilities and scenarios. You may control speed of a Motor as a parameter to cool a medium in a machine, in this case you may use PID controller function blocks which are capable of scaling and un-scaling, see the following sample: Standard PID Package - FB41 Samples If you only want to change the speed of a motor to adjust the speed of a conveyor, you just need to process the value calculated by logic or selected by operator by FC106.So, please consult the online manual of STEP7 as I attached it here. About the wiring , please consult the manual for VSD and analog output modules in the following link(Chapter6): SIMATIC S7-300 S7-300 Automation System Module Data Best regards, Hamid Hosseini AttachmentFC106.pdf (81 Downloads) |
