• How do you connect a VFD with R S T to 220 power single phase?

The below information is for your convenience; however, please seek the guidance of a professional electrician that is experienced with VFDs and electrical motors of this type.

A VFD (Variable Frequency Drive) for CNC Spindles that have input terminals labeled R, S and T will typically use the R and T for the Black (live) and White (neutral) connections and the PE (protective earth) will connect to ground (green).

Check this image for reference:

With the YL600-2S VFD, we have found that the R and S terminals are used where the R is live and S is neutral. Connect the PE to the green ground connection.

• AM NOT SURE HOW TO SET THE Z AXIS TURN ON/OFF LASER WHEN CREATE CODE. KNOW THAT ITS TYPICALLY Z-AXIS MOVEMENT DOES THIS - BUT YOU DONT SHOW ANYTHING HOOKED UP IN PLACE OF AXIS.

When the z axis is going down, the laser turns on. When the z axis is going up, it turns off. The z axis directions is only a signal that is either 5v or 0v. That determines the direction. In vectric, you will need to set your machining operations with a very very small depth so the time it takes to get to its final depth is a very short time.

• THE GANTRY MOUNTED SPINDLE WATER COOLER PUMP THAT I PURCHASED DOES NOT OPERATE NO MATTER HOW CONNECT THREE WIRES TO TWO WIRE POWER SUPPLY.

The 12V power supply has 3 terminals for AC in: N, L and earth ground. The output of the 12V power supply has 2 DC + and - terminals. Cut the connectors off of the ends of the fan and pump wires. Strip the red and black wires of both units. The fan will connect to the 12V power supply red to the + and black to the -. The pump will connect in the same way, but the white is not connected.

If you have a pump that has a grey and black wire on the large connector, the grey is the 12VDC V+ wire and the black wire goes to the V-. The extra wire does not need to be connected.

• How can we check our 1.5kw spindle. we get a dL error after we start to cut. it spins up fine. We checked IGBTs in the VFD and they're not shorted. We suspect intermittent short INSIDE the spindle. What do you think?

dL usually stand for a short that is occurring within the spindle or spindle wiring. I would recheck the wiring going from the VFD to the spindle, as well as the terminal on the spindle where there should've been some soldering required. We usually tend to either heat shrink or use electrical tape to cover the terminals so no contact or arching can be present.

Also depending on the VFD you have please adjust the setting pd008, to the voltage that is required (110V/220V).

• DO NEED TO SQUARE UP THE MACHINE AND IF SO YOU HAVE INSTRUCTIONS OR VIDEO FOR THIS?

The eyebolts are used in the squaring of the machine. I would use a standard carpenters square and first run the end mill along the edge of the square to first make it parallel with the long axis. Then run the end mill along the other edge with the short axis and adjust the eye bolts and chain according to the angle that the machine is out of square.

• How to display RPM instead of frequency on the VFD? I have the 2.2kv 110 volt spindle and inverter.

There is a button on the front of the VFD that will cycle through RPM, Freq, and a few other readings. If there is a >> button on your VFD, that will work. If there is a mode button on your VFD, that should works as well.

There is a >> disc button but it does not cycle through the display modes.

Is there a parameter setting to make this button work to cycle thru the display modes?

setting the starting rpm

the vfd will not start the motor

Any progress on this? I have the same issue.

Mine is a YL620-G-5.5Kw

That model will not be able to show RPM. You will be able to show the frequency, which can be used to determine the RPM. RPM equals the Frequency x 60.

There is an Icon for RPM at the top of the display I cannot cycle through the different options to see the RPM

At the top of my control panel is has 6 different lights which indicate what your seeing. in order from left to right they are COM, ALM, DISP, RUN, Hz, RPM I have seen the ALM light up on initial set up but that was fixes with a parameter change. The run light shows up when i turn the spindle on and and it is running. I am however not able to get any of the other lights to show or to get the RPMs to display

If you do see an RPM light on the display, that panel sticker may be a sticker used for many types of VFDs and the RPM is not used. There is parameter: P00.24 which allows you to pick what to display. The choices a
re:
0: Display current target frequency. This will display your knobs, potentiometer, setting, not the actual spindle frequency.
1: Display electric machinery run frequency. This will display the actual frequency that the VFD is currently sending to the spindle.
2: Display electric machinery run current: this will display the current the spindle is currently drawing.
3: Display input AC voltage. Self explanatory.
4: Display mother line voltage. This will display the actual voltage at the input.
5: Display output voltage. This will display the voltage at the UVW terminals for the spindle.
6: Display speed paragraph number SPx. I believe this displays which frequency is being selected (P07.00 to P07.07, or 1 to 8 respectively).
7: Display inverter temperature. This is the temp of the VFD, self explanatory.
8: Display input signal X1-X3/output signal. This simply shows the inputs/outputs associated with the external terminals.
9: Display user variable. This one I have not delved into, so it may be something to look into.
10: Display user count value. Same, this one could be useful.
11: Display temporary debugging variable. Haven't tried this one, so I can't inform of any useful information but it won't pertain to this subject anyway.
12: Display automatic multisegment run step and time. I haven't delved into this one either, but it won't show RPM.

• Is there any negative to using the 110 volt VFD compared to the 220 volt VFD?

The 2.2kW spindle will have the same amount of torque and strength using either the 110V or the 220V inverter. Nothing will significantly change in either application since the 110V inverter has a small step up transformer which will increase the voltage from 110V to 220V to run the spindle efficiently.

I'd like confirmation on this -- isn't there a cost in efficiency to having the 110v step up to 220v?

• I want to know when the second video on vfd (YL-600 2.2KW 220V) parameter will be available?

We will be starting that video shortly. We want to make sure we convey the information clearly. The parameters on the VFD are extremely extensive and is difficult to explain the parameters that will make sense to the average customer. We pride ourselves on making videos that send a clear message to customers and viewers that have never seen this technology before. Making an educational video of this topic is difficult.

• How to I calculate RPM based on hertz displayed/set on the 2.2kw VFD (110V AC version)?

To calculate RPM use this formula, in which you will have to find RPM's when you have Hz.
1 RPM = 0.01666666667 Hz
Formula: 0.01666666667 × RPM = Hz
On our VFD if you select the >> button about 3-4 times, it will change from Hz, A, or ROTT.
When the LED's are lit on Power, FOR, and ROTT, you should be able to see the RPM the spindle is running at, our maximum setting for these spindles is 400Hz / 24000 RPM.

press the shift key on the key pad and the led at the top of the display will move to the right until the Rot (RPM) led is lit the display will now show RMP

• I HAVE NOT SEEN ANY REFERENCES TO ENCODER FEED-BACK CAPABILITY IN OF THE HARDWARE YOU SELL. THIS A SUPPORTED FEATURE WITH HARDWARE/SOFTWARE SELL?

I haven't delved into using encoders with stepping motors too much. From my research, you need to have a controller that can provide the closed loop control, rather than software handling that process. I have also found from my research that using encoders on stepping motors is generally used to stop the machine in the case that the motor failed to achieve the commanded position for some reason and gives the user the chance to correct and continue with the job.

If you want proper closed loop control, it may be best to go with servos and servo controller that provide the closed loop control within the real of those two components.
