If you think it is the servo drive (MR-S..) try and swap it with another servo drive. Test the motor first to make sure it is not shorted though, but this most likely is not your problem.

It's probably a problem with the CPU card. Unfortunately it is one of the harder boards to change because it also contains the memory (Params, Programs, Tool Data, Ladder, Software....). Take a...
Take a look at the servo drives in the electrical cabinet. They should be labeled MR-S... What is flashing on the drives?
Hi Chandru
If he has an FX709 then there is only one board in the op panel. This is the second generation of the M2 controls.

The LD1 light should turn on in a normal situation. What...
You can change Y238 to 0 through the PLC I/F page. Under DEVICE type the address (Y238), under DATA type 0, and under MODE type 2 and then try to format. Do not power off and on before formatting...
It's definitely a problem with your servo system. One of your drives should be flashing alarm 43. If there is another amplifier/drive with the same model number (MDS-....) try to swap it. Make all...
For what type of controls, Fusion, Matrix...?
I hear that Kitamura is using Mitsubishi controls on thier machines.
Anyone have any opinions or experience with the Mitsubishi controls? Just wondering how good or bad this could be.
You can swap the encoder very easily to a new motor. As long as it is the same motor model it will mount up fine. Just make sure you line up the encoder shaft with the pin on the motor shaft. Also...
I worked on a mighty with a 500 control a long time ago that was doing something very similar. My memory is foggy but I believe there was a problem with the clamping mechanism for the tool on the...
You may be able to check if there is a backup of parameters on the Hard Drive of the control. Go to Data I/O page and press Hard Drive button. Press Directory Select and choose one of the...
You cannot write or read parameters to those drives. The parameters get downloaded automatically when it is hooked to a Mitsubishi CNC. There is no PC software out there that will do that like a...
It's a little known fact but I believe if you change the time zone on your pc to North America you can download from meau.com.
have you searched on Mitsubishi Electric Automation Inc. - MEAU Home You can find many manuals. I found two for FR-SFJ on their website.
Put the machine in HOME mode and push the EMG stop button. Press and hold RESET and then press the down arrow key. You should see a cursor on the time blinking. Input the year as YY.MM.DD and...
It sounds like your drive is in constant alarm state so that is the first place you want to look.
Alarm 24 means that one of the motor cables is shorted to ground and a 32 alarm is an...
I beleive the disk is in a special format that cannot be coppied with a regular PC. You will have to get a copy through Mazak or Mitsubishi.
The MRS servos are digital so even if you had the pinout it would do you no good.
shanthikiran, we need the rest of the numbers after the M01. There are many different M01 alarms so it is too difficult to tell you what the problem is without the rest of the numbers.
You may need to format the control. This will clear all of the machining programs, Tool Offsets, and Work Offsets but will not clear the parameters. It's not a difficult procedure but there are...
It sounds like you are describing the display on the CNC. I looked it up and I don't see an alarm that starts with a 2. Is it possible it is a 2 with the middle led off? If so this is a Z alarm on...
The memory board has a capacitor that will hold a charge for about 30 minutes which retains the data in the memory. If you can change the battery within a half hour you shouldn't loose any data. If...
E51 File open error. It's related to the battery problem.
First would be to get the battery replaced, which is obvious, but if it's not replaced you might have to do this all over again.
On with...
It sure does. You are hitting the software stroke limits set in the parameters.
There are two places the software strokes are set up.
1st place
Press the Parameter or Tool Parameter button. Go...
I agree.
If you can post the line in your program where this alarm occurs plus the line under it maybe we can tell you better what might be wrong.
There is a four digit number that comes after the M01 Operation Error. If you can get that number then I can give you a better description of the alarm and some possible causes.
Yes you will have to reset the home position. If I remember correctly it should be as easy as putting the machine in zero return mode and sending it home. Because all Mazak's have dog switches it...
The battery for the servo system that backs up the absolute position is getting low. 9f is a warning for that. Look for a unit called MDS-A-BT#. It will need to be replaced.
The alarms you see...
What kind of PLG is it? Do you have two gears with two sensors and a preamp board? Most T32's used this combination for C-axis and they are tricky to set up. You will need an ocsilliscope to...
It would help if you could get the alarm number that is flashing on the drives. This will help to narrow down the exact alarm that is causing the problem.
