New Build 1000x600x200mm (newbie)

Hi,
Don't make it more complicated than it is. And RTFM. Read the manual i mean Ok i read it for you so:

What you need to make all work in real life and what you would actually use are exactly 6 things:

1. connect the 3 wire cable to the VFD to power it - 2 x 230v AC wires to L and N to power the VFD and connect ground wire to PE

2. connect U V W to the spindle and the shielding of the cable to the spindle ground or body.

3. connect one of your BOB relay outputs to X1 and Com. When the relay is closed by Mach3 the spindle will start

4. connect via 2 wire the 10VDC output from the C6 board to the VFD, where +10v goes to AVI and ground to COM on the VFD. Thats the spindle speed control

5. optional: split the estop wire and connect both sides to the Y1B and Y1C, so when the VFD is powered all will be ok and the continuity normally closed, if the VFD trips due to bit dig in material or whatever the contact will open and CNC will Estop.

6. program the VFD:

assuming you have bought 2.2kw water cooled spindle you must leave all default and change only the following:

P002 just check if its right for the motor you have bought, 220V default value
P003 400


these 2 are not clear to me. Normally on other inverters its the only place to say the motor accelerates and decelerates for 10 seconds. But in the manual i saw other place also. So - program them as bellow and if the motor continues to accelerate after 10sec and is not completely stopped after command for 10 seconds, then clean them both to 0
P013 10 and remember at mach3 to make for 10 seconds spindle start and stop delay at the spindle screen
P014 10


P021 400
P025 0 this when you have successfully control the start run and speed via mach3. You wont need more to touch the VFD for any reason after that

P064 1 again-you don't need to touch the VFD once all is working, all can,should and i would say: for the sake of not forgetting something - must be done via Mach3 Do yourself a favor and buy a good screen like MachStdMill

P065 1 same what i said above

P067 0 believe me on this, you don't need reversal . the only thing that could happen is you make a mistake and break expensive bit, have been there, done that


PS. Thats it, its not so difficult. Check again what i say for any mistakes and be happy chappy

PS2. Yes, my VFD has connected PE ground both to the ground of cable that powers the VFD and both to the spindle cable and hence the spindle ground. Difference is that i have the separate ground connections on the VFD to do that / Mitsubishi brand/ So i believe both ways is ok. Even if you don't connect Spindle ground to VFD ground it will work, but remember to properly ground the machine itself
