    If it alarms when you command a split degree, that means the option was not spe'd at the machine purchase. The solenoid you are hearing during a normal 1 degree index is not a brake, it is the...

    How the control handles the tool changer is determined by the machine builder's ladder logic program.

    The Meldas 500 series have a tool "registration" screen that most builders will use. On the...

    So what happens when you try to run a program with a split degree command?

    IIRC, there was an M code that had to be commanded to engage the brake after commanding a split degree movement. At...

    The 15 is a fabulous control. Top of the class in its day. As far as getting an old one running after a long shut down it could be easy, or next to impossible. The control CNC and PMC parameter...

    On some Mori Seikis of that vintage you can split degrees. There were a few configurations. A 5 degree index, a 1 degree index, a 1 degree index and split degrees, and a full 4th axis. If you have...

    I also rarely use the spindle override on my 30 taper machine. I used it recently for the first time in as far back as I can remember. Doing a 5/8-11 threadmill for the first time. When it got in...

    Should be 2011 for backlash at rapid and 2012 for backlash at feedrate.

    It has been over 20 years since I touched a 3 series, but it seems to me that if you pressed a key for an axis (X,Y, or Z) then pressed the CAN button it would zero the readout. Only zero'd the...

    Is there a cable connected to CD1 on the main board? If there is trace it. If not, then that is where you will need to connect to and the style connector you need.

    You do have the rigid tapping option. Without the Enshu instructions for rigid tapping you are going to have to figure out what Enshu wrote into their ladder logic to enable the rigid tap function. ...

    Are you looking to test your code or find out about tolerances, warping, etc?

    If it's just to verify your code, take the money and time you are thinking about spending and invest in software to...

    DC motor with encoder can run in velocity mode if the controller is fitted with F/V conversion. Old Fanuc systems are a good example of that application. I suspect that the OP's machine does use a...

    This is interesting. What function on a mill uses spindle CS Contouring? I have only seen that on live tool turning centers.

    That's because it was the machine builder, not Fanuc, that decided to use an M code to turn on the mirror function. Should have been documented in the machine builder's programming or operation...

    Before getting too deep here, are you sure the machine has rigid tapping? It is an optional function that would have to be spec'd by the machine builder or buyer. What is the content of parameter...

    Don't know why Okuma did the dual encoders. This was on 80s to early 90s machines. No idea if they still do, but I doubt it. The CNC did compare the feedback of the encoders. Because Okuma...

    Older Okuma HMCs all had dual encoders standard. One on the motor and one on the screw. Have seen a few lathes with encoders on the screw when using a timing belt connection between the motor and...

    In general, scales are a good choice.

    Scales are not a cure-all for machine accuracy, but in most cases they help position accuracy. Adding scales to a poorly designed machine won't make it...

    wmpy was talking about the Fanuc motor behind the spindle motor.

    BTW, the Mitsubishi SuperLine motor is AC 3 phase, not DC.
