Thread: VFD Settings Huanyang HY01D523B

Hey G'day people,

Small issue with my inverter, well more operator error than anything..

My VFD works perfectly except for decreasing speed of my spindle.

I can increase speed using the up arrow using shift play the number and you can hear the spindle powering up.

Trying to decrease the speed though is another issue, I can decrease the numbers but the speed of the spindle remains constant. I have to power off and power on for it to pick up the numbers I have set.

Would anyone please be able to tell me which PD function controls the decrease in speed..

I've been at this for days now and I give up....

Cheers

Steve

Hi Steve,

Well I'm not a lot of help. I've just been out to the shed and tried the VSD on my drill. While the up and down arrows work just fine above 50Hz, as soon as I go to 49Hz the drill just slows to a stop and wont restart until the Hz is increased to 50 again.

What are your PD's up to PD007?

Hey G'day,

Thank you for replying at least..

Your lucky both your up and down are working mine is just one way atm..

Ok my pd000/01/02 are 0 - pd003 is 400 pd004 is 400 - pD005 is 400 then pd006 is 2.5 and pd007 is .50

I have a water cooled spindle 5w 400hz 24000 rpm don't know if its 2 or 4 poll - every thing is working perfectly my speed pot works fine - worked that out, stop button which stopped working now functions again I discovered that pd026 had to be set to 1.

pd072 and 073 control the amount of control you have with the speed pot.

I looked at pd078 which says up/down speed but that seems not to do much except change the increment at which you can adjust speed default was.01 Ive set it to .1.

So I am at a total loss why I can only increase speed one way and not the tuther..

Cheers and avagreat day.

Steve

Sounds like a strange problem, the only thing I can think of is that perhaps the decelleration time has been set to some very large number..

If you have been pushing buttons left, right and centre without the manual it could be anything.
Before doing anything else I would get a hold of the manual - PM me if you need an electronic copy.
I would then perform a factory reset as per the manual and carefully step through the commissioning sequence as per the manual before starting the motor.
The most important one is the base frequency (PD4) since some units are set for 400Hz and as soon as you switch them to FWD (or REV) the VFD may try and drive the motor to that frequency
I failed to do this on one of my instals - fortunately the VFD cut out before any damage took place but you cannot count on this.

Hey G'day Bob,

I've done a factory reset a number of times, I have the manual as well, I make side note on the manual as to what does what, the English translation is pitiful at best.

Problems occurred when I did my first factory reset.. In my case pd013 : 1

pd004 is set to 400 as per motor specs, the vfd and spindle power up to that frequency over a number of seconds so that's good.

Well I guess Im going to have to go through them one by one until I hit the magic spot - the manual itself gives no clues unfortunately..


Cheers,

Steve

My manual says a factory reset (PB13) should be 8, not 1.

What do you have the minimum frequency set to? PD 7, and PD 11

if your talking about pd007 its set to .50..

Its a strange problem, if I set pd002 to 1 and use the pot for speed control even that is a one way trip I can increase speed but not decrease it.

Ive seen a few people on the forums regarding pd013 reset is 08... and some are 01... it dosent seem to be consistent depending on what version vfd you have..

again thank you very much for going to so much trouble..

this really is infuriating./.. o-O...

Regards,

Steve

pd011 is set to 0 as per factory default..


Regards.. Steve

One thing. Are you assuming the settings are what the manual says when you restore defaults? Don't, there is a fair chance the manual and the VSD do match up. At least mine dont.

What are your settings PD0070-PD0077?
(these really shouldnt effect the button operation, they are for the speed pot....... as I understand it.... but who really knows with these manuals lol)

Stuart

p.s. You say its set to start at 400Hz but you can speed it up? thats makes no sense to me.

Hey Stuart G'day,

Thanks for biting into this one as well,

to answer your last question first, I set it to 400 to see if we can go backwards from that using the down arrow doesn't work. If I set it to 100 I can use the up arrow works fine spindle winds up to whatever. As you increase the numbers the spindle immediately responds but if you again try to reduce the numbers spindle stays at last set speed.

PD0770 to 077, 70 = 0 71 = 20 72=400 74/75 default value 0 76 default 0 not allowable and 77=0 not memorized.

Speaking of the pot same thing when I enable the pot I can only go one way speed up and not decrease speed.

As for the manual lol I have to laugh trying to understand it and to answer your question no I dont assume whats in the manual matches the vfd... In my case there were a number of inconsistency's one which was really annoying was when set to factory default the stop button wouldn't work on the panel until I fell over PD026 DEFAULT is 0 when it should be 1.. then the stop button cut power to spindle shutting it down.


Again thank you for taking the time to read the post.


Cheers,

Steve

Is it possible the push button itself is faulty?

Ray

Just so I've got it clear. If you start at say 100Hz then speed up to 200Hz with the pot, you cant go back down to 100Hz?

Hey Ray g'day,

Thank you for your post...

Button is working fine, if it wasn't the numbers wouldn't decrease on the display...

So it has to be a command not being sent to the spindle itself to actually decrease the speed..

eg speed 400, I can decrease to 100.. spindle still at max revs... stop vfd restart vfd and on start spindle fires up at 100 - use the up arrow increase speed and spindle responds immediately..

Steve
