Daniel_Iceland Posted October 25, 2019 Report Share Posted October 25, 2019 I am using a UMI-022BE-B1 controled through modbus to lift trash bins (on a truck) My problem is that when I am lifting a load and stop the machine fall back around 15 cm before stoping (see picture) I used to run the same machine with Omron inverters there I set the Injector DC-Breaking to stop and hold the load while the mecanical break took hold. But I am gettin the feeling that the Unitronics DC-Braking setting are mostly cosmetic since no matter how I play with them nothing happens. I tried using P013. Short Circut breaking. Both at 75% and 100% power for 3 second and the only thing that happens is that there is no breaking for 3 seconds. I have break resistors connected and have Energy breaking set (P08.37) but I have also tried turning that offf. Does anyone have any experience in tuning the breaking on these inverters? Is there something that I might be missing that turns of DC-breaking and Short-Circut breaking? Quote Link to comment Share on other sites More sharing options...
MVP 2023 kratmel Posted October 25, 2019 MVP 2023 Report Share Posted October 25, 2019 Please try to see P1.08=0 P1.09---P1.12 I'm installed application with high inertia and 3sec stop time (DECC =2.5sec, and DC-Braking 0.5sec) --working fine. Must use Braking resistor connected to VFD. P/S From manual... Remove the yellow warning labels of PB, (+) and (-) on the terminals before connecting the braking resistor; otherwise, poor connection may occur Quote Link to comment Share on other sites More sharing options...
