ZUKED inverter

[john fletcher 1Participant @johnfletcher1]

I recently purchased an inverter as shown. Has anyone already programmed a similar item. If so would they like to share their experience ? A copy of their program would be much appreciated. I am a complete novice on such matters.

May be a CW100 Manual here.

Comment: this is a super-cheap VFD, £28 from AliExpress, and although the product might be OK, very low prices often mean  “too cheap”.  Have to try it to find out.   Buying one second-hand without a manual is a serious gamble!

Even if brand-new, I distrust products with 5-star reviews that say:  The shipment came much earlier than the delivery date – 10 days. The merchant is very kind, good, responsive, and always ready to help with advice, information, guidance. I recommend this merchant, this institution. I have not tried the frequency inverter at work, I will give feedback further. I would give 10 stars. Thanks.   My bold – note review praises the merchant, even though the product hasn’t been tested at all.  Oh dear!

Another worry: the device is labelled “DANGER 5 min“.   I guess this refers to the duty cycle, that is the VFD is only rated for 5 minutes at full power, after which it has to be left to cool down before starting again.    Even though 5 minutes is ‘good enough’ for lots of hobby machining, the limitation is too risky for me.   Really bad if the electronics fail, and frustrating if the VFD keeps shutting down mid-job to cool off.

As to programming, this may not be a problem.   Although VFDs come with hundreds of programmable settings, recently made VFDs almost always come with factory settings that will do the job without the user having to change any of them.    Wire up as per instructions and try it.   It should control from the keypad and knob.   May be necessary to change a couple of parameters to switch to a remote speed control pot, or maybe to limit max speed.   Only if unlucky might it be necessary to dig deeper.

[Robert Atkinson 2Participant @robertatkinson2]

I’d second SoD’s comments.
The terminals clearly are not protected so the unit MUST be put in a suitable enclosure.
EMC and electrical safety compliance is anyones guess.
Did the supplier provide a manual?

Hi John. Since noone has answered what you asked the most of the imported far eastern inverters have a pretty much standard geometry. Find a similar one to get a copy of there manual & try it. Also try manuals.lib as there should be some on there which may assist you.

Steve. P.S I hope this positive comment is of some use to you.

 

[Robert Atkinson 2Participant @robertatkinson2]

The OP did not ask for a manual. Neither has he responded to my question as to if one was suppled with the VFD.

Using a manual for a “similar” unit can be problematic. Even similar units in the same range may have different parameters. Evn different firmware versions can change parameters. As SoD says try the defaults first.

It shoud be noted that VFDs are not consumer appliances. They are complex components that are intended to be designed into systems by competent engineers. Not picking on the OP, but if the buyer can’t read the manual and at least ask about a particular parameter they should not be using the device.
If it is not supplied with a usable manual in the language of the country it is sold in it’s not fit for purpose.

Robert.

[Martin of WickParticipant @martinofwick]

Try contacting the supplier for a manual / set up sheet.

Try searching for a manual based on product code.

This is the link sort of thing you are looking for. Although it is associated with the ZUKED brand, I would be very cautious in assuming the parameter set up is as per this information. It would be a minor miracle if it was. Look through the product specifications to find. Couldn’t find a way to download though. It may help with initial connections after which you are in trial and error land. Remember these things output dangerous voltages and currents.

Even the Chinese realise there would be little point in making a VFD with a 5 minute duty. The 5 minutes warning almost certainly relates to the time to allow capacitor discharge before you stick your fingers into the electronics.

In any case, you will need to mount it in a suitable project box if you intend to use in the operationally. If you want buy inverters from some bloke called Ali, ask the vendor to provide manual first, sometimes there is a rendition of the parameters sheet in the specification section associated with the product.

Hi John,

I googled this it gives you all the details if you scroll down their web page.

Hi Steve,

Can you see my post #753702?  It’s the first reply to John’s question and it starts “May be a CW100 Manual here.”

I ask because I’m developing a suspicion that the forum is displaying posts erratically.   Many reports of images inside posts failing to appear, but I think the forum may also be randomly failing to display entire posts.  If a bug, it doesn’t effect everyone at the same time – some see the missing item, others don’t. So far I’ve failed to catch a screenshot, and the developers need strong evidence.

Embarrassing to one and all if posts are going temporarily AWOL!  A few times recently, after reading what others have said on a subject, I’ve typed answers only to find someone else got there first.  Makes it look as if I couldn’t be ar$ed to read other contributions, which is rude!   As I have no memory of their post, either I’m going potty or their contribution wasn’t visible when I scanned the topic!

Last point; Steve’s advice that John should to find and follow the manual of a “similar device” assumes that the internal electronics and terminal connections of VFDs are identical, which is dubious!   Not a completely daft gamble because cheap VFDs from different makers might be based on the same chip set and implement the simple example circuit often provided with the data-sheet.  Or be rebadged versions of the same unit.   But beyond that there are many VFD variations on sale, making it unwise to assume manuals are interchangeable.     If Steve knows of VFDs with identical manuals, be useful to publish the list.

Hmm that appears to be a completly different VFD….

[Dave HalfordParticipant @davehalford22513]

More like one of this series

[john fletcher 1Participant @johnfletcher1]

Many thanks to all who have responded to my request, which was  posted by my granddaughter, I personally haven’t facilities doing pictures. I have been using inverters in my workshop for more than 30 years so not an exact novice here, unfortunately I’m not familiar with the latest terms. Not bosting here, but I could possibly be the eldest active member of this forum. The inverter was supplied with a manual in good clear English, no spelling errors, unfortunately many of the terms I have never heard of. I have a large sheet steel box in which the inverter it will eventually reside. As one contributor suggest, I will wire it up using CY and see how it goes. Many thank once again. John

[Martin of WickParticipant @martinofwick]

In which case leave all you are not familiar with as default settings and just check review the obviously useful ones such as:

• Parameter settings are as you wish for keypad and VR control or for analogue via the multifunction inputs
• acceleration / deceleration times ie  just the 1st acceleration time (unless you are invoking rotary switch multi speed control)
• braking type (as coasting or decelerating) assuming you are not using dc braking and a resistor
• maximum and minimum frequency settings (some come set at 400Hz for CNC spindles!)

Others you might find include

• start direction
• max motor current or rated power / rated current

probably some obvious ones I have forgotten,  sure others will add to list

[john fletcher 1Participant @johnfletcher1]

Back yet once again folk, all working straight out from the box. As I have previously said the enclose instructions are in good English no spelling errors. The booklet/instructions are as Dave Sillyoldduffer published CW100 Manual. I would like to have forward and reverse facility available, as much as I try I am unable to understand all the terminology used, could be the age thing. I’ve spent a considerable amount of time reading XSY- AT1 VFD on youtube and others. So, if anyone can point me in the right direction it will be much appreciated, or better still, a hard copy of what they have done. John

Agreed that 5 mins is probably capacitor diedown period.

There should be covers for all of the connection areas.

How do you control in if it is in a box ??

Best to wire in a remote control unit to it.

I have one that looks similar but it is fully insulated with integral junction box top and bottom. The fan is at the bottom rear and vents bottom front and has  no vents on top.  Instructions say use in dry ventilated dust free  area.

[peak4Participant @peak4]

John, I don’t know if this is any help or not, but it’s some notes I made when programming a cheap AT-1 inverter/VFD; as I recall this was when I set up my Herke tapper, with momentary push buttons & variable speed/
They made sense to me at the time, but it was a while ago.

For anybody struggling with the XSY AT series VFD manual cryptic control parameter descriptions, based on my limited testing. I hope this will be useful to someone. Further details set out below:

As suspected, all 6 of the analogue inputs are configured as active high, meaning the control logic is activated by an input signal and not an interruption of signal. There appears to be no way of changing this.

The VFD in its default state set no signal input to the non running condition.
The permissible control inputs are restricted, but do allow for continuous contacts via a latching switch (described as ‘wire’ switching, or momentary contact via a non latching push button arrangement described as ‘key or keying’.

The more useful input parameters for the 6 analogue input block locations 50 to 55 are as follow:

PARAM 1 wire control stop This changes the VFD default condition to run on power. With contact between com and terminal, the attached motor will not run. with no contact, the device will revert to the previous control state. It is unlikely that many workshop users will need to use this parameter.

PARAM 2 keying stop should really say key start/stop This uses a single non latching push button control to activate the motor. Push the button once for on, push same button again to turn off. It requires a contact set that is NO, or ‘push to make’ linking com and the terminal set as P2. useful if you only have one button!

PARAM 3 keying operation This changes state from default non run condition to the motor run condition and uses a single non latching push button control with a contact set that is NO. Pushing the button starts the motor, further button pushes have no effect unless the status has been changed by the input to another terminal.

PARAM 4 stop keying This changes control state from the run condition to a stop condition and uses a single non latching push button control with a contact set that is NO. Pushing the button changes motor run state to motor off but will have no effect ( it may however interrupt jog mode if pressed during jogging ops). P3 and 4 are used normally used together to effect two button RUN and STOP controls (if that is what you want).

PARAM 5 and 6 wire forward operation wire reverse operation These require a latched contact between com and terminal. Forward and reverse are relative conditions, so need to be set in the context of your particular application. used if a toggle switch or rotary switch operation is required. For example, you might set com on the centre of a 3 way switch wit rev one way and forward as the other. HAVE A CARE as leaving the machine switched to run and starting the VFD a couple of days later without remembering will result in a start up on powering the VFD. you may want to set parameter 1 in location 65 to avoid this.

PARAM 9 wire reversing switch This changes the run state from forward to reverse. When latched, setting the motor to run by another terminal, will cause the motor to run in the reverse direction. Unlatching will restore the original direction of rotation. Normally used with a simple toggle/rocker switch in conjunction with a wire run or key run input.

PARAM 10, 11,12 keying commands These are not well described in the manual.
P10 should really say Key forward/reverse switching). They are all momentary inputs requiring non latching NO push button control.
P10 allows a single push button to change motor direction, pressing the will reverse the current run direction and so on backwards and forwards. This function will only operate in conjunction with other keying commands (ie P3 or 11 or 12 in the active condition).
P11 will start the motor only in the forward direction,
P12 will start the motor only in the reverse direction.

PARAM 17,18 jog forward / reverse Self evident, use if you want a jog function. Can be used with a latching switch to connect com to terminal to hold in jog or NO non latching if you just want to ‘blip’ the rotation for a part rotation. See params 86 onward for controlling the jog frequency braking etc.

PARAM 19 E stop FWIW, a stop switch and all round missed opportunity. Requires a NO contact mode for your e-stop input. Can be implemented as latching or instant. Latching is preferable as it sets an interlock and prevents normal or jog start until unlatched. If you don’t have a latching e-stop, I suggest you also wire into another terminal set with P16 so it sets a fault condition at the drive as ERR 9 preventing further unwanted starts until the cause of the panic has been sorted and the VFD re-set.
Unfortunately, there appears to be no way of setting a braking function on the E-stop, the condition when you most want to stop the rotation instantly. You can set the brake to operate on the normal stop where you don’t really need it, but it doesn’t implement in the E-stop. Grind your teeth in rage if you will, but remember how little you paid for the device.

[Martin of WickParticipant @martinofwick]

So John,

How are you running it at present?

How do you want to run it, off keyboard on unit or preferably remotely via home made pendant with pot and switches?

If running off unit, have you tried pressing button M-FUN to invoke rotation reversal?

If remote control, what type of switching do you want – rotary  ie run forward / stop run /reverse or push button  stop & start, push button reverse / forward E stops etc etc ?

Is the CW100 manual what was included with your inverter?  The type controls have to be selected by parameter type listed on page 17 (assuming that the manual you have is correct and not some random product off the internet).

It is unlikely that protocols for the AT-1 will be of any use with your unit. Pleas do not start randomly changing parameters until we can confirm your manual is the correct one.

[SillyOldDufferModerator @sillyoldduffer]

My brains are frazelled by belly ache at the moment so this may not work.  Worth a try though because it’s simple.

By default the CW100 comes with terminal DI1 set to ‘RUN FORWARD’ and DI2 set to ‘RUN REVERSE’.

With the unit turned on (usual precautions), try connecting terminal DI1 to GND, my blue link above.  Fingers crossed, the motor should run forward.

And similarly, connecting DI2 to GND, my red link, should run the motor in reverse.

If it works these terminals are the starting point for designing a practical control circuit.

[Martin of WickParticipant @martinofwick]

Simple, possibly Ok, or simply disastrous, without clarifying at what stage in the set up the OP is at.

The MFIs will only operate in the way you describe if the control input function parameter has been correctly set for terminal input and likewise the switching parameters are set for latching (and not 3 wire or multi frequency or whatever weird and wonderful control options may be available).

You are making heroic assumptions that the CW100 is the correct manual for the unit and the OP has implemented (or attempted to implement) a pendant terminal control using latching switches.

We would do well to await more information from the OP.

Elf and Safety gone mad Martin!  Nothing heroic in what I’ve suggested; it’s not wild guesswork.

1. John confirmed the manual that came with his VFD is identical to the CW100.  We know what we’re dealing with here.  Stay awake at the back!
2. Nothing disasterous will happen if the control pins are grounded as a test.  The possibilities are listed on page 17 of the manual and it also defines all the defaults.

Up to John what he decides to do with our suggestions.  I suggest mine promises progress whilst Martin’s doesn’t.  Given what we know I think Martin is excessively over cautious.

Dave

[Martin of WickParticipant @martinofwick]

So…….wild guesswork, Hmm, I will let others be the judge of that.

SO YOU already appear KNOW, by some mysterious means, that the parameters P0 02 and P0 03 have been set correctly by the OP for terminal control? I can assure you that merely connecting D1 or D2 to ground will have no effect on anything unless that change has been implemented and suitable terminal switching in place. Without that, your approach will result in precisely zero progress!

In the event that P0 02 03 have been configured, it is true that the D1 and D2 are set for latch control in forward and reverse, BUT how do you KNOW  that the OP wishes to use a remote terminal – remind us how exactly? Is latched switching what he wants? maybe he is trying to implement 3 wire control or something completely different.

Maybe the OP (and we don’t KNOW how the OP is operating or wishes to operate this device or what he is using it for) is attempting to run purely off the unit keypad and cant find the reverse at that point. If that is the case the M FUNC may need to be configured correctly in Parameter P7 01 (assuming the manual is the correct one).

It is, Dave,  simply to do with fully understanding all of the OP requirements to come to a useful solution rather than wild guesswork, or the firing off of random suggestions of dubious time wasting value.

 

 

[Martin of WickParticipant @martinofwick]

Further, for the benefit of the OP I would suggest the following.

There is no point reading an incorrect manual (for the AT-1). It will be of no use. No use whatsoever. And no point requesting somebody else’s set-up either – Suppose they had it set for a 400 Hz spindle, with signal input control for advanced loop control motors. Their settings would be at best no use and at worst dangerous.

To save time, it would be helpful if you could tell us what you are using your VFD for, how you wish to operate it and what type controls you would like to implement for the piece of equipment you intend to use. Clearly, if you have used these devices before you will have a preference for particular control methods. If you do not wish to do this on the forum you are free to PM me.

I would, as others have done, encourage you to use a remote terminal or pendant for control in any final installation rather than directly accessing the unit, so much safer.  That is not’ elf and safety gone mad’ as some may suggest, but simple risk mitigation.

The VFD set up looks relatively simple, and the manual (if correct) while not comprehensive, is adequate for setting most of the usual workshop operations.

 

 

[john fletcher 1Participant @johnfletcher1]

Well, many thanks to all respondents. I should have been more clear on what I would like. I have a Myford lathe controlled via a 30 year old inverter which developed an intermittent fault, a nuisance. The lathe has a remote  control box with latching and push button switches, wired up and installed by me. CY wiring to the motor and screened for the controls. As the original inverter was a pcb 180 X 260 mm it  was mounted in a ventilated steel box. I had remote, for/rev/jog and speed control, I would like to have the same again. Worked well, never had any problems with the chuck running off.

I have read CW100 manual as suggested by Dave and cross checked a lot of the listed items, they are the same. I think one is a copy of the other, as far as I can see both manuals are the same, only difference one manual has larger pages, so the page numbers are different.
