Hi, I found the answer - the Arduino GND and +5v must also be wired to the encoder logic of the Gecko. I thought they were opto-isolated in the Gecko internally (step/dir from encoder) but apparently...

Hi, I found the answer - the Arduino GND and +5v must also be wired to the encoder logic of the Gecko. I thought they were opto-isolated in the Gecko internally (step/dir from encoder) but apparently...
Hi, I am controlling the Gecko by an Arduino 256 board.
The step signal works great and the motor turns according to pulse train.
Direction signal has no effect and it has been tested on both...
Hi just so people know I dropped off the VFD and motor in question of at Al's place, he lives in a mansion...
In the meantime I've ordered the water cooled equivalent 2.2 kw combination as an...

I've been doing alot of Arduino based projects lately, seems like the logic end wouldn't be such a big problem, my late uncle left me with a nice oscilloscope maybe I will begin an...
Starting to sound like a good call
This motor doesn't have a connected ground, and I never fixed it. That being said it ran great for the last 8 months. I barely looked at the youtube video. However when my motor runs it only consumes...
Hi and sorry for the lack of updates, has been a very busy time.
The setup did work, but the Hyunyang VFDs don't hold up well, have just fried the second one after a harsh move of the CNC to the...
Yeah I'm fine admitting wrongdoing here if we can find it, the spindle has cost me a lot of time and money already. Memorized the instruction manual, but still unclear.
PD070=1 is confirmed as...
Pd 070 was Set at zero for pot control on the keypad. I haven’t tried hooking up external pot yet. Other settings have to be confirmed tonight. Thanks
I used factory setting for about 5 seconds to see what difference it would make. All his recommended settings have beeen put back into the unit and I have no control over speed far as I can tell....
With me its always the hard way.
I reset to factory settings and ran the motor for a few seconds, and the pot worked as a control. But all other parameters were factory reset.
Since the pot...
I am using the exact settings you posted from page 5:
Huanyang Mactec54
2.2Kw 220v 400Hz Air Cooled
PD000=0 ( 1 For Parameter Lock )
PD001=0 (1 For Remote Control)
PD002=0 ( 1 For 0-10v...
I confirm the settings but my base and minimum frequency are set at 400 hz so maybe the unit is locked at high speed, factory settings seem to be lower. I think Ger said 100 hz is doable? Like 10k rpm
Hi, making an update, I ordered in a replacement spindle and it works. I now have two VFD's that were used to test the old motor.
It looks so far like the initial frequency was wrong (50 hz...
Wmgeorge suggested using a tester that can read up to 400 hz. The reader we used to measure the 150v didn’t have a frequency reading option. Does that invalidate the reading, or does that tell me...
The drive doesn't fault without load, and the drive outputs on UVW without the motor 150 volts, on each pole to ground. According to my electrician cousin who did the reading the VFD needs to put out...
I may buy one of these cheap replacement units:

Sorry I was short had a rough afternoon.
There are plenty of people running these spindles without any special wiring. I want to why the motor ran so good originally with these wires and what...
The wiring is connected. I’m not picking up the recommended wire because it cost over $1000. I have braided shielding that can go on top. I will check the setting tonight but I did go thru the...
What if I bought a new VFD and plugged it into this motor
The numbers are 1.3-1.5
At the moment the motor still runs but only reaches a couple hundred rpm if that in a minute or 2 and gets very hot then the VFD throws an over amp error message. The...
I had an over amp error a couple of times, I can get exact ohmmeter readings later but they were in the range of .5 -.8 last time
If I replace the spindle only, and the drive is faulty, what would the risk be?
What ohms should the windings read to know for sure?
btw Mactec thanks for the suggestions on wire.
What recommendations on a new setup?
What parts of this spindle are salvageable?
The wiring will need improvement but I can't see how that explains the motor not functioning at all now.
It went from running at maybe a couple thousand RPM yesterday to about 100 RPM today and it...
Ok I have changed all those settings over to what you said and with the same result.
Ok lesson learned, must have been 50 hz at some point. This really sucks out $300 bucks now
Is there any...
I’m following the YouTube video on configuration of Huanyang VFD. He put 50hz for US. I have only changed from 400 to 50 for this video. It did not affect the speed for some reason. I am away but...
Hi, I've uploaded a youtube video of the motor in action including throwing the error code.
The motor is making sort of a grinding noise when it runs seems like as compared to near silent running...
How do we know if the preload is correct?
