...So the H016 is some indication of speed (Hz?) - what was the error code?

Also... did the spindle start to spin?, or at least grumble a bit?

...and have you seen this post...

...I've not reviewed it in detail - but superficially it looks good.

Didnt do anything or any noise


Interesting ...........got to go back to work so will let the Mrs have a go , told her it will be ok to stick her fingers in the VFD wiring

Hi Doddy
Just seen this ,,,bugger .never mind onwards and upwards.
Here is a few photos of the VFD that i purchased today , I bought this one as i didn't want to go and spend a load of money on a real good one yet as i would like to see if this set up works first and if it is viable .
The wire for the spindle was marked from 1 to 4 to start with so i soldered Wire 1 to pin 1 . Wire 2 to pin 2 and so on ( this was on the socket for the spindle.
And using my tester on the connectivity setting i tested each wire and connected them as follows

I connected the No 1 wire to the V
No 2 wire to the W
No 3 wire to the U

Then i pressed run and turned up the speed and at H 16 an error message came up.
any ideas please

I do think that VFD parameter setting is the way forward on this. But, just thinking about the wording above - I understand about 1 to V 2 to W and 3 to U - that's fine. Provided that the wires 1-3 on the motor are connected to the windings. 95% convinced that they will be, but work checking. You said "using my tester on the connectivity setting I tested each wire" - I don't quite understand your meaning. If I was testing which 3 of the 4 wires then I'd use a multimeter on the resistance range, and measure between wires 1-2, 2-3 and 3-1. These should all read about the same - somewhere around 1-3 ohms (I'm throwing a bit in for meter leads etc). And 1-4, 2-4, 3-4 should be open-circuit (possibly a high value if 4 is connected to the spindle metal enclosure - especially if held in your hand whilst measuring. If I squint hard enough at your words I could guess that's what you mean, but it's worth checking. VFDs don't particularly like having no load connected, and hate having a load disconnected when running, so worth to double check your understanding of your wiring before you power-up again.

Let us know how you get on with this, and the parameter setting. Oh, and note down the original settings for each parameter changed, if already set to non-factory setting in the manual.

Sorry Doddy what i meant to say was with my tester i made sure that the wires went to the correct pin as the wires only have numbers on them with no color to them .
we have copied and put in the parameters from the attachment you sent and here is the result .
The spindle was wining as if it was turning but didnt move until i gave it a spin by hand but once it got to 32000 or there abouts it shut off and ERROR 6
and on the instruction sheet it says error 6 is OVER CURRANT PROTECTION

[Doddy]

Okay, Pete. It's important now to make sure we're on the same page. As tedious as it sounds, can I ask you to post the settings on the VFD from P000 through P127. I know it's a ball-ache, but it's important that we don't make assumptions on what's set in the VFD. Just do it in blocks of 10 - it'll take 10 minutes no more.

For one thing - "32000" - you shouldn't be able to display that, let alone get the spindle to spin at that.

Thanks Pete, appreciate that took a little time. Similarly it's taken a little time to review that. I can see where you have applied the settings linked in the other post on the same labelled XSY-AT1 VFD. Looking at your photo of your manual - there's some small conflict between your printed manual and the settings in the other thread. It could be that different variants of the XSY-AT1 have different settings - good old Chinese crap.

*** FIRSTLY - LOG ALL CHANGES MADE FROM THE ABOVE PARAMETER LIST FROM NOW ON! ****

*** SECONDLY - CHECK THAT YOU'VE VERIFIED THAT YOUR SPINDLE IS WIRED CORRECTLY *** - I'm concerned that you wasn't getting rotation originally - that suggests that your wiring to the spindle is incomplete (one wire disconnected could result in this - you wouldn't get the three-phase rotation with only one coil energised (okay, the other two series-wired in parallel with the first - that would explain why you needed to spin the spindle to get rotation).

DO THESE BEFORE CONTINUING - If there's problems with the wiring then ignore the following...

Anyway, hopefully you made a note of the original values for those changed as I'd suggested?, because some of the parameters mentioned in the link are not included in your (shockingly poor) manual, for example

P078-P085 - not described in your manual, the link I provided says to change from 3000 to 7000. What were these originally set to? (another manual for this VFD says this is the overcurrent settting, so I can understand the value of 7000 (your motor is rated at 6A - or 6000mA). If you have the original values and these were set to 3000 - these could indicate that the parameter is simply excluded from the manual for some strange reason.

Other thread recommends:

P068 = 220 (under voltage setting) - your manual defaults to 160/270 (220V/380V variants)
and
P069 = 255 (over voltage setting) - your manual defaults to 300/500 (220V/380V variants)
... I believe the defaults in the manual to be honest - you can expect your voltage to be measured by the VFD around the min/max of 220/255... I think you need greater head-room - the manual defaults appear sensible. I'd recover these parameters to these. (P068=160, P069 = 300) unless you encounter other problems. Erroneous values would result in over/under voltage errors - you're not currently suffering these.

P067 = 28500?, your manual claims a default of 32500 (I struggle to read the text in the photo) - that parameter should not have been changed - I'll assume you didn't and the value was different to the manual's default value. P067 = "Voltage coefficient"... I've not got a clue what that refers to, and the manual doesn't explain it. There's no near-neighbour in other VFD manuals that I've read.

P021 is listed in your manual as "Reduction Ratio" - default 1 (range 1-100),the link and your setting is 2800 (other manual says - RPM/50Hz). What was the default value if/before you changed this? If this was previously set to 1 (as the manual indicates) I recommend you reset that back to 1. If the default before you changed was 2800... then your manual is just wrong. Let me know the original default value set in the VFD.

P024 is listed in your manual as overcurrent protection buffer - default 3 seconds, link sets to 6 - I'd recover that to 3 to be honest, at least for now. The spindle should get to speed within that time and the current should be stable. Reducing from 6 to 3 may INCREASE the frequency of overcurrent trips, but will protect the VFD/spindle. If




P034 controls the spindle acceleration - the manual claims a default of 50Hz/S (takes 8 seconds to get to 400Hz - max RPM) - your value of 25 will take 16 seconds - very slow to accelerate. Ironically, an online version of the manual says default should be 25Hz/S (so your VFD defaults appear to be consistent with the online manual, not the manual provided - go figure!). P042 is the deceleration - similar. That parameter should not have been changed from the other link - so I assume the value 25 is the default and the manual is wrong? Jazz suggested slowing down the acceleration... I'm cautious - it's already chuffing slow. Worth playing around with, though - try the manual setting of 50 will either improve, or worsen your experience - try it - it shouldn't break anything. Remember to recover to 25 if 50 worsens things. You could try 20, or 15... but it will have a detrimental impact on spindle accel time.

Spindles will take more current than they're rated for during acceleration. I'm really hesitant to recommend the following, but in the absence of any obvious accelaration-over-current setting, and with the P024 set to 3, rather than 6 (as above)... and if P078 was originally 3000, now 7000, then try this at 8000. If, during accelaration the spindle current exceeds the 8A for the time set in P024 then it'll trip. I'm hoping that reducing P024, and tweaking P078 up a little, that the VFD won't trip during the critical acceleration phase, and the spindle will get up to speed. I'm not keen on this solution, but we're fighting a VFD of limited settings.

OK bud
Am checking my wiring from the start again . I wired as i said 1 to pin 1 2 to pin 2 ect but as another check is there a color code used as in say RED to U or Blue to W and so on

[petesos]

Hooraaaaaay this poxy chinky spindle has finally started up and spinning and the problem was in the wiring now its running in reverse but that just needs a wire swapping over i am sure ?????? .
The wiring from the standard black box that came with the machine was all marked from 1 to 4 and no colored wire So for anyone who has bought one of these i sugest you just unscrew the wiring jack on the top of the motor and check fromk the colors if that makes sense and not rely on numerics that someone has written on them .
But now to swap the wires to get it running the right way .......any ideas please

What is the best speed to run this spindle at

8 seconds is about the right amount of time to accelrate to 400hz. So if it's not working with 16s then it will only get worse.
What's causing it I've no idea and I can't read that manual very well because the pictures are crap.!
