Philips, Grundig, Millplus Information Collaboration

Hello!
I have a DMU 50V from 1996, with Philips PG1220 Series, Grundig Millplus control.
Who has images of diskettes with software, please share by e-mail: [email protected]
Thank you so much.
 
I was having problems with my 2000 DMU50V with Millplus 4.0. X53, X04, Z04, and other errors related to the E stop chain usually when opening or closing the door. I received some advice from another member and replaced some of the Estop relays in the cabinet and some of the relays on the DDC boards. That helped a bit and I was able to make parts but occasionally still had to stop and restart to keep the machine going. A few weeks ago, the control stopped at boot with an M71 error (no power to PG1220). Tried to restart but the screen was blank, no power on the PG1220. Power supply for the PG1220 was dead. I did see evidence that at some point, the 5 mosfets were replaced along with a few other components. Ive had the machine since 2015 so it was sometime before that.

Power supply is a Philips PE1927/71. Looked on ebay and there were a couple used units in Europe and Indonesia for $1400 or more. I searched around a bit and saw an identical power supply designated as a PE 1927/23B. It was only 69$ so I bought both that the seller had for sale. I looked it over upon arrival with an electrical engineer buddy of mine and he confirmed it was the same except for the voltage input jumper, which was set to 120VAC on the $69 PS. Installed it, checked the voltage outputs on the test points of the PG1220, and so far Ive had no errors at all after making a few parts. Might be helpful to know as it seems like a common problem with these older DMG machines. Im sure it was just the fets that were bad but it worked out in the end.

If anyone has a schematic for these supplies Id like to get a copy. I searched far and wide and didn't see anything online. Philips sold their PS division to Cherokee at some point, and Cherokee merged with another company so its probably all lost.

Good afternoon.
Made resuscitation of the hard drive, rewrote the parameter file. Bios set up:
1. Submenu "Memory Shadow" disabled
2. BIOS Embedded Extension Configuration BIOS Extension Base Address all disabled
During the boot process, DOS gives two errors:
1. umb upper limit segment address f88a
2. Microsoft Interlnk version 1.00
Connection NOT established
Driver NOT installed

After downloading the program, there are no errors.
When moving any axis in manual mode, error E60 is triggered.

Hi everyone, I just found this forum and it seems like a great idea to try to keep dmg millplus alive.
I have a dmu50v with millplus v310 with a lot of manuals and wiring diagrams.
It will be a pleasure to be in contact with you and to be able to share.
Hello, you have private message, if you can help me with documentation
Thanks in advance!
 
Привет всем . У меня dmu50v с MillPlus 1996 года. Когда я набираю команду T1 M6 смены инструмента, появляется ошибка E252.
кто-нибудь решил эту проблему, пожалуйста, помогите. [email protected]

Hello, maybe you still have the wiring diagram of this power supply or the pinout of the output connector.
I have the same problem now, and I would like to replace this power supply with a similar one, but with a more technological base
 
The problem with the PE1927/xx power supply is a well known problem. The 1927 etc. P/S components have reached their end of life and are VERY DANGEROUS still to be used in the control. The Mill Plus has no over temperature protection, so if the P/S overheats, IT WILL JUST BLOW UP AND BURNING HALF THE CONTROL MODULES. We had several customers, which had the P/S repaired by some local shop, only to having it fail a few month later, taking half the control with it. Sometimes we could repair it, if we had the parts, but the bill was exceeding Euro 15000. The alternative was to scrap the machine .So please be sure you know what you are doing. We at ROBTEC don't even test the repair-controls with this P/S at all, but replace it with a new one.

I looked around for schematics and never found anything for this power supply. I would just keep checking on eBay and look for the exact supply or for the part number I cross referenced in the post above. Mine is still working fine since I installed it none of the other issues I had before replacing it ever popped up again. The other thing I recommend is to put a fan on the chassis to blow, filtered outside air into the chassis where the power supply is located I did that on my machine.
