Worked on number 22 robot tonight. It alarms while stacking the parts on the belt during the down stroke at random pack numbers. The alarm is displayed as a Y inverter fault and it states the Y speed cannot be controlled. I changed out the y-axis encoder, switched the Y and Z inverter cards, and checked all the connections to the circuit board under the x-axis cover. I checked the different voltages on the main transformer to make sure they were within tolerance and monitored the inverter power supply voltage while the robot was operating and everything seemed ok. I tried changing the y-axis pack speed to different values also.

Inverter Fault
Anytime the Wittman gives an inverter fault, try and recognize which axis the fault occurs on (x, y, or z).
Thanks.

#22-robot stopped once at 1:30 a.m. for a "inverter fault". We powered it down and re-homed it and there were no more incidents.?
Did thorough PM's on robots on presses #7 and #11. They were in definite need of cleaning and lubrication.Also cleaned the control cabinets very well.
Give me a call if there are any questions. I plan on taking Friday the 18th off (last 12hrs PTO).

Wednesday C Shift
Mark extended the y axis up roller switch on the Wittman today so that it could approach closer to the mold before the clamp opens. This switch controls the secondary mold close interlock.
I didn't do anything on the floor.
We did schedule Branson welding training for next Tuesday. I also got a PO cut for training on the Star robots. It will be scheduled for after the first of the year.

MP- 1 thru 8 - Vacuumed oil pans, checked & lubed tie bars, & blew out control cabinet filters.
MP- 17- The oil pan ran over. The oil recovery pump clogged & oil went over the float switch; pump runs continuously. I could’nt find anymore switches;
I’ll check w/ Collin & see if he has one.

#22 Robot
There wasn't enough operators to run the hoky top covers tonight but Charlie and I went ahead and syncronized the robot on 22 with the ejectors. With the robot running at 100% global speed, the ejectors need to be set at 28%. We moved the cups and also dropped the EOAT positive stop bar down to keep from hitting the runner.
Also while setting up number #5 robot the CPU faulted out and had to be cleared. I noticed the pentant light is almost out. I'm not sure if we have any hid away anywhere. If not it I can order some and make them a stocked item.

Tuesday A Shift Part B
Before I left I programmed the Wittman for the Hoky “Top Cover” (80083) that they hung in MP22 today. There was not a set up in the Nissei, so the only thing that cannot be changed on the machine is the clamp full open position and the eject forward position. The only thing on the Wittman that needs to be changed is the cup position on the EOAT. Also, the way the teach program is written right now, you have to time your eject speed so that the ejectors get all the way out just before the robot gets to the mold face (When robot is at full speed. First cycle, the robot will only run 30% speed. To change, in Auto, from the main Wittman screen, hit F6 to increase overall speed and F1 to decrease). First cycle the eject speed needs to be ran REAL slow so that the robot can get there before the part falls off, and as you increase the robot overall speed, you need to increase the eject forward speed.

Tuesday A Shift Days
Hello All,
Not much going on today with me. I was watching an auction most all morning and in meetings most all afternoon while Mark covered the floor.
I did have to jump out the hydraulic filter clogged switch on MP4 today, and last weekend I had to jump it out on MP5. I know you get this alarm sometimes when the oil is cold, but we may also have some legitimate filter clogging.
Thanks

Dec.7th A Shift
We ran the Wittman today on the Hoky Chassis in MP22. Runs well, but some of the lights on the sub-pendant still do not work (Manual, Operate with/without Robot, Auto-Cycle Pause). Swapped the bulb on the Operate with Robot light, and it still did not work. Outputs for lights coming from Card A22 in the Cabinet (Operate with Robot light is Output A5). I didn’t troubleshoot it much past that so someone still needs to figure this one out because it confuses everyone not knowing which button(s) are engaged.
Also got MP 5 tuned in today and dry cycled. It is ready to run. They are going to try and run the baseplate in it this afternoon.

Worked on PM's and cleaned this weekend.
I wired the Dummy plug attached to 22 just like the one Josh was using so it should be O.K.
The only ones that do not have dummy plugs attached to the machines at this point are #2, and #3 presses.

MP 8 – robot touch screen display – “ waiting for download “ – Thought I would have to reload the program; I unplugged the interface cable & plugged it back in
& it came back up.
After the press was started, the left side palm button on the fan housing press broke. I robbed one off the spare press & installed it.
I found two new ones in the assembly maint. cabinet – installed them on the spare press. There is one new palm button in MRO. I put the old one I had
left, in MRO molding spare parts.
