Mp#1-Put together a water manifold sheild to help direct any future leaks.
Mp#23 robot- Made a sprue gripper extension to pick offset runners (work order request). Helped them get it going.
Mp#21 robot- Replaced a section of tubing that had blown out.
Used 10x6.5mm metric tubing.
Put the new molds in the tool room.
Call if there any questions.

MP-23 Control power kept kicking off. Mark and I checked it out; found the 3 amp control breaker was bad – replaced.
MP-5 Installed “T” for gauge @ pressure transducer port.
MP-8 Made a fixture to check for bad ends on fan housings.
MP-1 Cleaned up water under clamp. Cleaned & checked operation of cabinet fan.

MP01 is still down with the servo drive alarm. Mark is still doing some investigating before we send the thing in for repair.

Mp#1- Motor power goes off after 1 second, then alarms "5E33" Clamp axis driver error (regeneration abnorm).
Checked it out, found wires burnt open from what appeared to have gotten wet. Repaired regen circuit wiring. Alarm on servo amp cleared but alarm on machine display still comes up as before.
I downloaded the Yaskawa manual for that particular servo amp and motor, it indicated that there were maybe a few solutions to this error.
1. Replace the servo pak
2. Replace the regenerative pak (it could be defective I suspect).
3. Repair wiring to regenerative pak.
After making the repairs and reading further, I found that resistance specs for that servo pak model was 2.4 ohms. We have 3.4 actual now.
This is why I suspect a faulty regen pak.
There is reference to an incorrect pulse count vs. pulse set value, this is supposedly a result of this cause, which may be cleared (with the host controller)if I knew how to do that.
We would likely need that digital operator that we just now ordered to do that?
I turned over everything I had to Mark when he came in and I think he is going to see about making sure that any internal faults get cleared and seeing what else can be done aside from ordering new expensive parts.
Call me if you have any specific questions.
Also worked on the Hot stamp press on #20. It was not reading the down switch and had to be set-up correctly.
