text: <s>[INST] information hi, my name is Luca, I just started using Rockwell.I have a question? With the power flex 40 i can monitor engine load and then adjust the speed. es. A motor that is moving a propeller in a dense material. if the motor go to 30Hz and at some point starts to grow absorption, the motor have difficulty Then increase the frequency and forced the motor a higher speed. My problem is...how do I monitor the uptake? the power flex40 has a parameter or do I put a current sensor. PS.sorry for my english [/INST] Hi Luca, and welcome to the forum ! There are parameters that you may use to get informations about the motor current and speed...see the User Manual, chapter 3-3, Display parameters...there is for example the d003 - Output Current ; you may monitor this parameter to see how many amps the motor is absorbing.Now, if you need to retrieve this informations from a PLC, either you may use an Analog Output of your drive, setting it to be proportional to the Output Current (A065), and wiring it to an Analog Input of your PLC, or you may use a communication option module or the embedded RS-485 port to exchange data with the processor. If you will opt for the second option, please post again with the PLC model and the communication option you would like to use, a Forum user will be able to suggest you something that helps. - fuzzy logic \\n </s>
