if you have a dc axis motor machine and you are doing a high start stop duty cycle on the spindle you may want to put a dwell in the program to let the regens cool off. g4 p1. is dwell 1 second. the dc buss vokltage on the screen is only a feedback and is not to be relied upon. the only way to get the dc buss voltage is to measure it with a meter. if you have hi voltage coming in to the machine ans the transformer set wrong the machine will send the excess voltage to the regens. you can also ohm out the regens and make sure they are within in spec i think the older machines had something like 15 ohm regens. if the regens just get hot from sitting around it is usually the incoming voltage or you need a servo distribution board. |
