    M01 0004 alarm means that an external interlock input has been read by the PLC and sent to the CNC. I'll try to get some time tomorrow to look at how that is implemented in the ladder on my machine.

    Can you verify the M04 operation error? I don't see that one in my info. Post the entire error message and any codes on the alarm line.

    Not only location can affect a potential customers quoted sales price. When I was doing field service, I saw several times where a customer that is known or rumored to be a PITA got quoted a higher...

    Only if all features are created in the same operation. Many turned parts are processed in two operations where the accuracy of the second op workholding will introduce a concentricity error.

    Should be a number after the Y51 alarm that will help determine what the parameter issue is.

    The EX1047 alarm says that your PC spec parameters have been cleared. To set those you have to turn on...

    Quite often the case when thermite notices a thread. I suspect alcohol and an old man's memories may have something to do with it. At least that's what causes me to ramble occasionally.

    Easy enough to check. Scope test pins 3 and 4 to 0V. Should get a wave form P-P at .35-.5V. DC mean voltage at ~2.5V. Frequency based on speed (helper turning spindle or motor by hand). If you...

    Not sure. I'll try to get some time today to research those parameters. My M50 does not have them in that range. Do you have those parameters as hardcopy? If so, post a couple pics of them so I...

    And 40 taper is so weak compared to 50 taper. I don't get the constant 30 vs 40 taper argument. They have different capabilities. Each will outshine the other when playing to their own strengths

    Parameters 1-16 are the option and configuration parameters. There is a method to enter those at the control, but I have never been able to figure it out or learn how. They are entered when to...

    Just because an indicator light turn on and off on a prox sensor, does not mean it is working properly and sending the input to the control. You need to verify the state of the input signal at the...

    Many of the parameters will be very specific to that machine. Unless you find someone with an identical machine to get them from, you should try getting them from the manufacturer.

    I have only used 98 and 99 in parameter 38. Then setting the GOP parameters and cycling the power has restored the operation panel. After that then you will have to address the issues with CNC...

    Your control is built on Mitsubishi hardware with the Mori U/I and touchscreen.

    Start by initializing your GOP parameters if you have them all backed up. Do you use the "conversational...

    My schematic shows that pins 7 and 8 are the outputs of a quad comparator (LM339) at location MG7. The inputs to the comparator are the outputs of a dual op amp (LM1458) at location MF3. Seems like...

    When you say you are " bringing to life" this machine can you further describe what the condition was and what you have had to do? This helps a lot in narrowing down the possible problems.

    Those alarms are from a Yasnac control. Dan's suggestions are a great starting point. Kind of feels like a power supply issue. Need a little better back story too.

    I got my CNC and PLC backwards in the earlier post. Yes, Y addresses are PLC outputs to the control and machine. Y208-Y215 are the PLC outputs to the control for the various modes.

    Not just Siemens. Pretty much every controller has gotten some bad rep due to poor integration by a builder. As would be expected, most cases where the machine builder is also the control builder...

    I have always used a 4mB SRAM card to do the backups because it always works.

    I have never tried this with a tool registered as a sensor, but on many Mori mills, M33 returns a tool in the spindle to the magazine.

    The folks that grind spindles in place as a biz have their grinder on its own set of ways. This eliminates the condition of the machine from introducing error in the grind.

    Not at the CNC level, but the mode selection can be changed by the PLC during auto operation if the machine builder wrote some logic to do that for some reason.
