Problem on yaskawa v 1000

[cleve]

Problems with my programmable spindle drive Yasawaka v 1000 3 hp. AC, . Intermittent problem at first with spindle stopping and not starting with the monitor giving an error code of 105 and the V1000 giving an EF3 error. Now the problem is not intermittent.The motor tries to start and then the error message comes up . Has anyone have or seen this problem before. If so would you know the cause or solution. The drive is on a new Protrack SMX 2 The 105 error on the computer says check the AC drive module and repair as necessary. When you read the error code on the V 1000 it tells you that the spindle has just down from an external problem. I just purchased this machine and am trying to figure out how it all works.
