Reply with QuoteHere is the setup that I used with my 2.2Kw spindles and HY02D223B VFD. It should also be similar for the 1.5kw air cooled with a few exceptions in the VFD setup.
First, disclaimers, this works for me, but setups vary so you are responsible for making sure it works for you, secondly I am not an electronics engineer or electrician and we are dealing with high voltages here so treat appropriately and double check everything.
Finally this is for setup in the USA with US voltage, it may be different in other countries
So as I mentioned I am using the 2.2kw water cooled spindle with the HY02D223B VFD, CNC4PC C11 BOB and of course Mach 3.
First the physical connections;
1. Power into the VFD. I am using 220v 1 phase with 2 hot lines and 1 ground.
Connect the ground to the terminal on the VFD marked with the ground symbol on the bottom left. Connect the two hot leads to the terminals labeled R and S (does not matter which goes to which and I believe you could also use the T terminal but I have not).
2. Power from the VFD to the spindle. You need a 3 core cable to connect the terminals in the VFD labelled U, V, W to any of the 3 pins on the spindle connector, again it does not matter which one goes to which pin.
3. To control the speed of the spindle from Mach3 you need a BOB (like the C11) with a variable speed control that converts a step signal to 0-10vdc. You need to follow your BOB board instructions to calibrate this, but basically you need the output from the BOB to equal 10v when you select maximum RPM in Mach 3 for the spindle.
Connect a cable to the ground and the 0-10v terminal on the BOB, then connect the 0-10v to the terminal in the VFD labelled VI and the ground to the terminal on the same row labelled ACM (there is a second one on the up row of terminals).
4. To control the power on and off of the spindle from Mach 3 you need a BOB (like the C11 from www.cnc4pc.com) with relays. Again follow your BOB's instructions for setting them up.
Connect a wire from the relay (I connected to the normally open side) and from the V.in on the relay to the terminal on the VFD labelled DCM and a wire from the NO terminal on the relay to the terminal on the VFD labelled FOR.
Okay that is it for the physical connections, now onto the program items on the VFD you have to change.
PD001=1 (this means you won't be able to run the spindle from the VFD as you have now given control to an external terminal - Mach 3)
PD002=1 (this means you won't be able to change the spindle speed from the VFD as you have now given control to an external terminal - Mach 3)
In this order
PD005 = 400
PD004=400
PD003=100 (this is particularly important for the air cooled 1.5kw spindle to prevent you burning it out as the cooling fan does not come on below this frequency)
PD008=220 (this should already be set but just check it)
PD044=1 (this set the FOR terminal to be run rather than put the spindle into CW direction)
PD072=400
PD141=220
PD142=8
PD143=2
PD144=3000
That is it, you now just need to make sure you have set Mach 3 up correctly as per your BOB.
Again, this works for me, but I make no guarantees for any one else setup.
Hope this helps
