We are using G120 VFD drives on wrapping machines that got converted from micro master. Now micro master vfd ran ok, no problems. The G120 has a fault F7807 only when jogging. That means turning drive on and and off several times quickly. Motor where checked and are not grounded. This problem occurred on several machines. What do you suggest would be my solution? ------------------------------------------------------------------------------------------ |

Hello, Because you mentioned quickly restarting the drive please check the de-energization time of the drive. Like mentioned in the fault description unsuitable times could lead to a ground fault. |
With best regards, |
