    2 speed 3 phase motor?

    So, At 60 Hz it can be a 4-pole or 8-pole motor depending on the winding chosen. This is typical in a modern CNC. 3-contactors. This explains how it is done on most Air Compressors. Look in section Star-Delta. It also explains how the safety and interlock circuit work...

    If it is a cooler only, and not providing lube oil to the gearbox, Velocite 4 or 6 is common. If it is also lube oil, a DTE series would be common.

    That is a oil cooler with a attached tank and pump. the temp should be set near '0' and not the lowest temp. It matches the ambient temp at 0. It is to control temp rise from the gearbox / hydraulic systems in operation. Makes the machine more stable during the day.

    2 speed 3 phase motor?

    If the 2 speeds are half / double speeds, It might be a wye-delta switch gear. Very common on modern CNC spindles. It switches over the motor windings for a 'electrical' 2-speed gearbox of sorts.

    Mazak Nexus 200-II M problem

    I am sure that original message has been fixed in the past 2 years. Error 0c can have more than 1 cause. This just means it failed the error checking. If the software reinstall does not fix it, we just replace the entire control.

    Mazak Nexus 200-II M problem

    The reinstall software is already inside the control. But you could seriously mess up your software install if done incorrectly. You could overwrite or corrupt the reposition device and that will brick your machine until Mazak makes a on-site service call to re-set this. Become friends with...

    Mazak Nexus 200-II M problem

    We have had the same issues many times. Windows will boot fine, control will hang on the Mazak Splash screen. Error 0C. When the controls get near the 10-12 year mark the memory card inside begins to wear out. You can re-install the Mazak software and that will usually fix it for a while. Until...

    You don't specify wire size. So I will assume .010. Here is the 2 settings I would start with on my Alpha1-iC. My 'R' technology doesn't work after a software update. So I will not show it.

    Weird problem with Fanuc RS232 blowing fuses

    Fanuc controls feed +24v on pin number 25 on most machines. This is for portable DNC boxes. ( FANUC Handy-File and the like ) That is what the micro-fuse in the back of the LCD is protecting. This is not the multi-amp fuse feeding the entire LCD. Check pin 25 against the Frame Ground (...

    Fanuc 18i Card Reader Errors

    The older 18i series are picky about the cards capacity and formatting. 32MB max. Fat12 file system. Format the cards in the control. If windows says there are issues with the cards after you go from CNC to PC, do not let windows 'repair' the card. Windows tries to change the binary header on...

    Why should I get a Fanuc control instead of a Mitsubishi?

    Fanuc has a much longer life cycle for control support. 15 years after a control is no longer made, the critical parts are still available or a 'upgrade' replacement is available.

    Are milling chucks obsolete?

    Old wire

    Hitachi Seiki VK45 Z axis alarm help

    Record your EXACT version of this board. There were many revisions over the 8 years this was made. Should be 16-02-00-xx for the 'old' version. And 16-02-02-xx for the new version. The new version has a dependency of a matching LSPC board. Not backwards version compatible.
