Thanks for the help! We called FAGOR today,and finally found the problem. It was 3 simple parameters. The spindle speed MAXGEAR1 through MAXGEAR4 must be set accurately. The value is how the control and drive scale the RPM. Next the voltage values in P37-P40 are how the control syncs the spindle speed. You can use the values,and a hand held Tach to accurately set the spindle speed, to the indicated control rpm. Lastly the voltage param for the spindle drive output must be set to both + . The control default set is one is + the other - . The yaskawa drive wants only a + POS value for speed control,on a three wire hook up. Thanks Again for your help. |
