Friday, 01/03/2014, at the end of the work shift, I was made aware that an Allen Bradley Ultra 3000 Digital Servo Drive faults occasionally with an E05 (Motor Over temperature) fault. I do not work in the area and was unaware of this problem. Our boss wants a solution. I talked briefly with the guy who runs the sealing equipment in that area and he told me the drive gets this fault a couple of times a day and he cycles power on the Ultra 3000 to clear the E05 fault and then the equipment will run again.
My boss said he notices it faults everyday about a half an hour after production is finished, equipment is idle. His office is only about 25 feet away from the equipment so when the Ultra 3000 faults an Alarm horn sounds (drives him crazy) he has to come out of his office onto the plant floor and silence the Alarm horn.
The operator of the equipment, in that area, said he also leaves the door of the Ultra 3000 Digital Servo Drive cabinet open to cool the drive control. But as I sit here at home (Saturday) thinking and writing about scenario I am realizing the OT Fault is on the Servo Motor.
These Ultra 3000 Digital Servo Drives are brand new to me – no experience / training. I do not know at this moment what type/brand the Servo Drive Motor is - but do the Motors actually have a thermal switch/sensor on them? I’m also thinking I should feel the Drive Motor to see if I actually feel any excessive heat.
The Ultra 3000 drives are on Device Net and we use A/B RS_Logix5000. On Friday, using Device Net, I quickly looked at the many parameters but do not know what they all are or if I can adjust any to get rid of fault - if Motor is not actually overheating.
If anyone can give me advice I would appreciate it. I would like to have some sort of a plan so when I go to work on Monday I can try and solve this problem. Thanks in advance.
