Dear all, would anybody please know if it is possible to select a ramp for analog output selected by multiplexer ? I have basically four inputs (from TD) and they determine what voltage goes to my Micromaster inverter. I would like to use a ramp but only when one of the inputs is selected (F4). Not for the others. The reason is that the machine can not initially handle a load of material coming of it. So I was thinking either to use a pulse relay output for first time period where the stop time is much longer than the run time (without alternating the frequency = no ramp), or use a ramp for the initial period to slow down the motor to the minimum revolutions. I am not sure which of these is feasible, or easier to implement. Thank you very much for any hints. Yours Sincerely Karel AttachmentSaw Dust Drum.zip (453 Downloads) |

Hi, with a block ramp you can set the parameters L1 and/or L2 over a pointer to an other block (counter or analoge blocks..) - perhaps that solves your question. In addition i give you some circuits and perhaps you can find some ideas to create your own ramp-function witch you can control ever you wont...
