220 vfd

[transformer82]

I thought I had this post on the right part of the form but ill try here.....ok I bought this vfd its a kinda 2.2/220v vfd model kd200-00220s2 I tried to contact my supplier and the company with nothing...it says 220v and from what I know is that RST + ground for 220 but mine only has scews terminals with ground R and T ...here are some pics thanks to all advance

also theres a pic with jumpers have no clue theres nothing in the manual

This is mostly likely because this particular VFD only requires 220V into R & T. Make sure you also connect the Ground. The motor connects to U,V,W.

The jumper settings will need to come from the VFD manual.

The other connections on the green terminal strip are pretty common you can look at Hunyang manual . The terminal with S-,S+ might actually be a modbus connection, but again you really need the manual, especially because you need to know the parameters that must be programmed in the VFD.

Looks like you have the Kinda VFA manual in the picture it should have all the info you need?

As I figured the S-,S+ is the RS485 modbus interface. You don't need to touch that until you step the computer interface to allow you to control the VFD from a computer.

Attached you will find the manual that has all the details and connectors on the VFD.

there absolutely nothing for wiring and I cant find anything for the jumpers ....vfd to spindle is not the problem ...but only having RT through me way off.. and anything is the crapy manual was pics of 3 phase input RST....so form the last reply R and T are my hot....leads.. and of course ground.... as for setting parameters all they say is different % but ill get through that part ..just trying to figure out the pins 123

[transformer82]

so the s- s+ is that the same as pwm? I'm new to all the vfd

[CNCMAN172]

Look in the manual I uploaded in that RAR file it has detailed instructions. RS485 is NOT a PWM interface. This is a differential interface that sends messages back and forth. There is a language interface call MODBUS that allows you to control the VFD using Mach3,Mach4 and many other CNC software solutions.

The wiring of the VFD is detailed in the manual I uploaded for you. You are only going to two connections for R,T for the 220VAC. You also need the GROUND. Then U,V,W go to the motor. I HIGHLY recommend you read the entire manual I uploaded before you connect any power to the VFD/Spindle. Also keep in mind you must set the parameters correctly before you attempt to spin the spindle with the VFD. You can burn out both units if the VFD is programmed incorrectly. This is really important. I have not seen this particular VFD but the parameters are most likely very similar to the common VFD you see on this forum like Huanyang, and others.

Look at the manual and let me know if you have questions. Good way to spend a Friday night.

thanks a lot cncman172 that pdf has a lot more then the manual I have thank you

Glad that helped you out.

Here are the setting you need to change on your VFD, after reviewing your manual. This VFD is actually a pretty nice VFD, these settings should get your started. Your VFD has something called auto-tuning where it sets several other parameters by itself, similar to what some Servo Amplifiers do, so that is something new I have not seen on a VFD, so that is pretty nice.

Try setting these parameters, please read the sections of the manual I have highlighted below.

Russ

Read Section 4.2 on modifying the parameters
Read Section 4.8 on Auto-tuning


Initialize basic parameters F0 & F1 groups

F0-00: Inverter model cannot be modified by user, it gets set automatically
F0-01: Control mode 2 V/F control
F0-02: Running command source 0 Keypad, this will get changed if you use Modbus or other method to control vfd
F0-03: Main frequency source A selection 1 Keypad potentiometer
F0-08: Keypad reference frequency 50 Hz?? Not sure what this should be, probably 400 Hz as well but you might need to test it with different values. Maybe MAC on cnczone has seen this one before?
F0-10: Max frequency 400 Hz
F0-12: Frequency upper limit 400 Hz
F0-14: Frequency lower limit 100 Hz this will be about 6000 RPM, the manufacturer recommendation
F0-15: Carrier frequency Model dependent?

F2 Group: Motor Parameters
F2-00: Motor type cannot be modified by user, it gets set automatically
F2-01: Rated motor power 2200 this is for a 2.2KW spindle motor
F2-02: Rated motor voltage 230
F2-03: Rated motor current 9.6 amps
F2-04: Rated motor frequency 400 Hz
F2-05: Rated rotation speed of motor 24000 RPM
*F2-06: Stator resistance
*F2-07: Rotor resistance
*F2-08: Leakage inductance
F2-09: Mutal inductance
F2-10: Current without load

* updated automatically with auto tuning.

thanks a lot russ .. I tip the hat to you good sir..

[CNCMAN172]

Please be very careful when you test your setup. There is lethal voltage on the VFD both incoming power and outgoing power. For your initial tests I recommend you have water pump hooked up to the spindle. People forget this and get really excited when it starts running and start playing with the speeds and sudden the unit gets red hot and burns up. If you power it for 15 seconds that will not happen, but do your self a favor and just setup a simple bucket with the water pump and then you can run it as long as you like. If it does not sounds smooth as glass when it starts something is wrong turn it off immediately. You have something set wrong.

Before you wire the spindle to the VFD always check the connector on the spindle and measure the resistance of each connector pin to the spindle body. Many spindles have 4 pin connectors but they do not have the four connection actually wired internally to the spindle. You should only find one pin with a low resistance measurement to the spindle body, that will be the ground pin. If you find more than one pin with a low resistance to the spindle do not start the motor and do not hook it up the spindle is BAD.

Make sure you have a ground that comes from the 220VAC source, and that needs to travel along with L1 and L2. You do not need any other wires for a test other than the incoming AC power and ground and the four wires going to the spindle motor. U,V,W and GROUND.

The spindle cable needs to be 16/3 with GROUND and braided shield. Do you just use the black SO cord you can find and Home Depot or Lowes. You need the cable with the braided shield. You need something like this one on ebay, if you fail to use the wrong type cable you will get the motor to spin but you will have so much EMI noise in your system it will give you constant ESTOP errors and crash constantly. Start off with good cable and avoid all those type headaches.

This thread is a huge help! I got my KD200 VFD to work with my 1.5KW spindle, but it is running at 1/10 speed?! Minimum RPM is set for 6,000, and I am getting 600. Same goes for the top end, 2,400 NOT 24,000. Any ideas what parameter I messed up?

[DingbatCA]

Got it (1.5KW 24000RPM Water cooled spindle, adjust accordingly).
F0-10 and F0-12=400Hz
F2-01=1.5KW
F2-02=220V
F2-03=7A
F2-04=400Hz
F2-05=24000RPM.

And if you want to display the RPM during running, then you need to set:
F7-03=401F
F7-06=0.6
F7-12=0

Here is the "how to" link:
Kinda setup in Russian

To reset your Kinda KD200 to its factory defaults:
F0-27=3

Many thanks to the good people at kinda-vfd.com for helping me figure this out.

glad you got it up and running .. I love mine works well my only problem with mine is I cant stop it @ max speed with out the break installed .

Look for the Parameter F0-18 for Deceleration start this at 10 and then reduce it, 2 to 5 is not uncommon for these drives depends on what spindle you have, and it will be fine, you have not set all the important Parameters this is one of them, by not setting all the important Parameters you can damage the VFD Drive

just tryed it and was a no go did not work 319hz i tryed to stop it and throught a error.. but it will shut off no problem @ 260 hz

[transformer82]

just set mine to 20 for f0-18 to 20 and now at 400hz 24000 rmp shuts down good

[mactec54]

So what parameters have you set, there is obvious some that are not suited for your spindle

Set higher with the deceleration setting

what was the error Fault ???

Try these parameters ( 1 ) at a time

Set F0-24=1

Set Fl-07=2

[transformer82]

f0-17 is set at 10 so was f0-18 raised it to 20
