Hi mbosko, There is no software problem!!!!!!!!!!!!!!!!!!!!! The error message “position not echieved- -79” is because the software (which is working fine) found a problem. If you have the message “position not echieved”, you have a screen (TV) on the machine.

The machine number 5831039 and 6431245 tells it can be a machine with or without a screen on top. The board AR is for the older version of machines (without screen).

Configure your POLAR D 115 cutter with performance-enhancing options tailored to your own requirements. POLAR cutting machines (in the graphics industry also known as guillotine or paper cutter) are durable, programmable cutters with hydraulic drive units.

The first question would be: “Do you have a screen or not?” If you have a screen you will not find a board AR in the machine. Coloured paper. Thank you for help 'position not achieved' is not error message just conclusion. Yes your machines are from the EMC II (2) generation. To answer your question correct the program 0 beginning with software version V3.0 and later has the following information’s: Step 1: Multiplier for backgauge compensation (EMC only). This is a factor for operating the machine.

Step 2: Special false clamp number 1. The customer could order an additional special size for the steel plate underneath the clamp.

The software needs this information, because the machine generation EMC II has a software limitation for the backgauge movement. Step 3: Special false clamp number 2.

The customer could order an additional special size for the steel plate underneath the clamp. The software needs this information, because the machine generation EMC II has a software limitation for the backgauge movement. Step 6: Slowdown travel. The backgauge motor has two windings for two different speeds. Before every positioning the speed will change from fast to slow. The computer has to do this early enough. The slowdown travel is just information how long it takes to change from fast to slow.

Step 7: Table air cushion OFF by using the foot pedal yes or no. If the operator cuts paper the air cushion should be switched off in the moment the foot pedal is used. If you cut heavy board this is maybe a bad function and the operator likes to have the air on permanently. Step 5: Information about the brake afterung. The service engineer can see the difference between the order (let’s say you like to go with the back to the position 20.000) and the reality (let’s say the backgauge stops at 20.004). The information will before example 0.004. This information if for one positioning procedure only.

This means every position you have to read out this number again. Step 4: accuracy allowance (normal setting 0.008 mm).

This is the factor for the software limitation in case the backgauge position was not good. If the backgauge is not correct positioned the software will stop the automatic function, the number in the display for the actual position will flash and indicates the error. The step 5 can tell you how much your positioning is wrong / off. You have the flashing in the display which tells you the positioning is wrong / off. The step 4 would give you the possibility to tell the computer that you would like to have a tolerance of 0.01 mm. This would mean you have every positioning an error message.

Or you tell the computer that you would like to have a tolerance of 1 mm. In this case the cutting will be not so precise. There for the factory setting is a tolerance of 0.08 mm. The real positioning accuracy in a new machine had been round about +/- 0.02 mm. So far the program 0 This all will not help you! Because the computer works fine. The problem you have is related either to mechanical issues or a wrong measuring of the position.

Let’s start with the mechanical issues. The backgauge in your machine you have to grease every eight hours with the correct oil. Therefor you have a pump on the backgauge. In the operating manual you have a list of possible oil. One of your machines was built in 1988 and the other machine was built in1994. This means the spindle, spindle nuts, etc.

Can cause this trouble. You have to calculate for every year between 50.000 to 100.000 backgauge movements for a one shift operation. The same problem you may have with the backgauge motor brake after millions of cycles maybe the brake has to be adjusted or maybe even replaced. Underneath the table you have a linear measuring device with a trailer cable.

I think in your case the cable is working fine. But the linear scale may have some trouble. The other group of problems is related to wrong measuring. Maybe the linear scale is not just worn, maybe it is broken. The electronic components which are controlling the electrical function for the backgauge stop are older and do not work very precise anymore. Over all If we would make a statistic about the most possible problems I would say 1. Adjustment of the backgauge motorbrake 3.

Spindle and nut gone or Linear scale broken 5. Electronic components This is your situation Coloured paper. If you are in manual mode you can cut whenever and where you want. If you use a program the automatic function is switched off the machine is asking to position again. If the wrong position is always too late (this means like in your example you overrun the requested position) I would check the display very correct.

There is a maybe a situation where the position (for an extreme short moment) is good and then it jumps away. In this case maybe the linear scale is broken or the trailer cable is not free moving, because the scanning head is shaking.

If you cannot see the correct stop for a very short moment I would start checking the backgauge motor brake. Do you know how to adjust this kind of brakes? Coloured paper. Awe come on Coloured paper, I've been watching this thread waiting for your instructions. I have the same problem on a Polar 137 EMC - Monitor, however I have adjusted the brake. Not sure if I am doing it 100% correct because it will work fine for a few weeks, maybe even a month, then start with 'position not achieved' again. When this is happening the hand wheel to move the back gauge is hard to turn.

I adjust brake and everything is ok again for a while. One note maybe this is just a fluke but last Friday this happened, I moved back gauge by hand wheel forward and after a few turns, it got easier to move and problem went away for rest of the day. Back gauge is getting oiled, brake does not seem overly dirty.

I have a POLAR MOHR 115 EMC SN- 5232101. On the front panel there is three windows that shows the digits for when the back gauge moves. The small window to the left has nothing shown. The middle window has a decimal point shown. And the window to the right has a decimal point and a zero shown. When I move the backgauge it's not showing anything in the windows just the same thing I describe. The original problem we had was when you removed the backgauge closer to the knife the digits in the center window would register when you go away from the knife the digits wouldn't move wouldn't change.

So I was told to check in to the linear motion slide I took it apart and cleaned it and I noticed the little glass that was held on by for dabs of silicon for centering purposes and reading purposes had fell enough. So I reattached it with Superglue being very careful and put it back together. When I first turned it on it seemed to work fine for a second or two and then it went to what I originally described in the beginning to the start of this discussion.

Anybody know what happened. It's driving me crazy. Hopefully someone has a way to resolve this problem I have already checked the cable it all ohms out well from end to end on each wire in the shielded cable. The linear slide pick up sensor everything looks to be good the ribbon cables fine the placement of the glass for the reader is perfect. Just need some advice please. Thank you very much.

Dear Sir Good day, hope you are well. After i did study his problem please test this: 1) Measure the Voltage at keyboard and display BT: +9Vdc tolerance 8.4-9.6 max if this voltage is NOT in the range you must to repair power supply for +9Vdc or Replace 2)Measure voltage a Keyboard BR: +5vDC Tolerance 5.08-5.12, if out of range Replace or repair Power supply. 3)I do not sure if you are given the right name to Linear measurement glass, this devices in single term: take the measure by Shielded Cable(special) and transmit to the Computer(CPU) if the Linear Glass or Shielded cables is faulty. You must to replace. 4) By other side, the ribbon cable is very difficult to measure with some Tester, there are special instruments for to do it, Example in test instrument for Network.

But is very expensive. I am recommend to test with some other machine or some colleague that has another similar machine.and test it. Otherwise replace, since Flat ribbon cable transmit Data. 5)Will be a Good idea if you can send me some PICs,where the problem that you are talking about. Since i Know the tech terms, and i do know if you are mention rightly. By other side, maybe you have problem with the PCB Keyboard: dry joint+solder joint+corroded joint. Take some Pics for me.
