Hi, The MANUAL does state very clearly what 2 & 4 mean in the F011 description, did you manage to read this? But does it really add any value to the end result - either the drive, cable or motor have an issue. There is an overcurrent, it is clearly higher than the set threshold, drive trips to protect hardware - end of. Myself, if the application permitted, I would disconnect the motor power cable, change the operating mode to V/F and check if the drive still trips with F011 to test for faulty output stage. Clearly, testing the cable and motor would also be a sensible thing to do. Have you clamped the output cores to get an idea of current readings? Is the mechanical system free to move? Is the encoder direction correct? Back to basics is always the best approach. Regards, Graeme |

Thank you for the manual Graeme. The manual that I have did not have any fault values in the overcurrent fault. Maybe I was looking in the wrong manual. Anyway, I am pretty sure it's not a cable or motor winding issue because this problem occurs only when our film production line is put to "thread-mode". When this mode is activated the speed of the production line is reduced from 280m/min to 8m/min. Speeds of all the motors are reduced accordingly. This is the only instance when this fault occurs only in this motor. It didn't happen before. However, If we manually reduce the speed gradually from 280m/min to 200 to 100 and then 8m/min then this fault doesn't occur. Therefore I was interested in the fault value to find more information. |
