Hi friends,

Check on Your machine panel, for a similar axis drive and you could exchange them (eg. Swap drives on X axis And Y axis) and see if the alarm 8 problem shift to the other axis. If after swapping,...
axis amplifier
The Alarm 8 problem originates from the Fanuc servo amplifier and normally it occurs because of its internal components failure rather than any mechanical failure on the axis. I have solved many such...
It could be the video signals cable between Cnc and the crt. I had similar issue with Fanuc OM, where the screen is "intermittently" not stable. As the saying goes, "at last" I took the video signal...

Ref. Tamagawa AU5589-6590-1382.. it is the spindle magsensor amplifier PCB & feeds amplified signals into the spindle drive.
It requires +/15V power to operate. The outputs PA & PB are...
UPDATE: For the benefit of this forum users, here is how I worked around this problem and solved the "issue" by the following method.
1) Set both APC and APZ = 0 (PM 1815 for B), an alarm will...
300 APC Alarm : B axis need ZRN; 309 APC Alarm : B axis ZRN IMPOSSIBL.
We have these two alarms on an OKK MCH-600 Mill. In addition, CNC also throws up Alarm 90 (REFERENCE RETURN
INCOMPLETE) when...
Does the B axis gets clamped after positioning to a certain angle, before the heavy cutting / rough milling is commanded? If no, then Try clamping B axis. Other possible reason could be the B axis...
Dear sir,
May i request with you for turret procedure?
this is my email : [email protected]
Appreciate your help. thanks.
Hi cnc2149,
Thank you for the motor and Drive combination information. These are very handy and useful, for those of us who wants to ensure good quality in our work. Appreciated.
Alarm 8 is due to internal fault with the internal PCB circuits. we may need to repair these drives in order to use them.
Fault may be with the feed rate selector switch. you may check the switch status on the diagnostic screen.
After you got the motor repaired, did you get the encoder re-aligned to the motor shaft so that the poles are in line with the coder signals?
Check the deceleration limit switch for Z reference. could be faulty or the deceleration dog moved off.
Did you check the coupling between motor and the Spindle? Is it V belt coupling?
Rishikesh,
H106 has higher current capacity and its size also bigger. and H104 has lower current capacity and smaller in width. If there is space on Panel to accommodate H106 in the place of H104,...
Dears,
handy information indeed. It will be useful for techs on site very much. Thanks.
Hi, my profession is to repair electronic PCBs on CNCs, Servo Drives etc. Based on the information seen here, I think the TH1 could be a Crowbar protection for the 5V ? (could be a thyristor). Check...
Check the x axis servo drive. abnormal sound on motor is due to fault with its feedback circuits.
Though the rated current on label are different, both these drives use same type of IPMs. On this basis, they both can handle the same power rating.
hope it helps.
Hi,
We have a Mori Seiki SL 204 CNC Lathe with MAPPS MSG-501 Controller. Spindle and Servo Amplifiers are Mitsubishi MDS-C1-SPM & MDS-C1-V2 Series.
Occasionally during CNC operation, Spindle...
Hi LT1TRUCK,
Please note, I have couple of these Heidenhain UV105 POWER SUPPLIES with me.
My answer may have come to you several years late! But I just saw this thread. We are specialized in...
Hi, has anyone encounter a problem with Display, where vertical line appears along side each character?
Attached is the sample picture of the said problem on the machine, a Moriseikie MSD-516 with...
One more suggestion to add: Check whether the belt between the Spindle and the Motor is loose. Tighten if required. (normally it is a toothed one or a V shaped belt)
I sense, this problem bit tricky.. In a closed loop system, everything is a suspect, until you find out the culprit. We have to eliminate one by one. Let me try with my 2c...
