Hi Guys
We have a conveyor cabinet (4years old) that has 14 powerflex 4's for 14 1hp motors. Today after powering up, 2 drives would not powerup. Incoming voltage ok (460v). We ordered in 2 drives and replaced. When we powered up cabinet after changing, NOW 3 more (different) drives will not powerup. After about 10 minutes with power on, 2 of the drives then powered up. Changed out last drive. Powered up all ok but 1 drive took about 5 minutes to power up. Any toughts on what is happening here? Somebody must of ran into this problem before. Today I removed all MOV jumper links. Not getting much help from AB tech. I would perfer input from the guys on the frontlines.
Thanks
