    Huangyang 2.2kw VFD pd177-180 Errors

    Hello,

    Just got my Chinese 2.2kw water cooled spindle and VFD connected and put it through some tests. Thanks to all the available information out there everything went smooth and seemed to work well.

    However, after successfully testing the unit for a while (20 mins), I stopped it and checked pd177-180 for error codes and each one showed an error code as follows:

    pd177: ELu.n
    pd178: ELu.d
    pd179: ELu.A
    pd180: EEr.n

    From the manual I understand these to mean a Low Voltage fault during accel/decel/constant run as well as an External Interference fault during constant run.

    The VFD is connected to 240V and spindle is connected via shielded 18 AWG wire.

    Does anyone know what common causes for these faults would be? Also is there a way to clear the fault codes? I have not discovered a method yet.

    Thanks,
    Justin

    Re: Huangyang 2.2kw VFD pd177-180 Errors

    After another look through the manual I found the fault clear parameter - pd172. Setting this to 1 will clear the faults.

    Re: Huangyang 2.2kw VFD pd177-180 Errors

    FWIW, I noticed that many of the parameters were already set to what I needed rather than the factory default. It is possible this unit was tested/used and not reset to factory. So I did a factory reset (should've been the first thing I did in hindsight, but didn't know what I was doing yet), cleared the fault codes, and have been testing error free for a while.

    Re: Huangyang 2.2kw VFD pd177-180 Errors

    So, I'm assuming your water cooled spindle is a 1 HP 240 volt 3 phase model (7,000 rpm?) and runs from a 2.2Kw (3Hp) VFD...….not a water cooled 24,000rpm brushless type?

    It is not advisable to do a Factory Reset unless you really have to quite often this can mess up these Huangang VFD Drives

    So did the Faults stop the Spindle from running ???

    Or was it just faults in the fault registry, these can be just from the factory when they tested the Drive or from someone that may have returned it

    So what parameters do you have set, t is important that you have them correct for the health of your spindle and drive

    Re: Huangyang 2.2kw VFD pd177-180 Errors

    @handlewanker HY02D223B Huangyang VFD (2.2KW 11A) with a 2.2KW water cooled spindle (24,000rpm).

    @mactec54 The faults did not seem to affect the operation at all - it seemed to run fine. Here are the parameters I set after resetting the VFD:

    PD001 = 0
    PD002 = 1
    PD003 = 120
    PD004 = 400
    PD005 = 400
    PD006 = 2.5
    PD007 = 0.5
    PD008 = 220
    PD009 = 15
    PD010 = 8
    PD011 = 100
    PD014 = 12
    PD015 = 12
    PD070 = 1
    PD072 = 400
    PD073 = 100
    PD141 = 220
    PD142 = 9
    PD143 = 2
    PD144 = 3000

    Seems to be working fine, temperature is cool both to touch and the water. No faults have shown up yet.

    Thanks for the help guys. This is way I posted here, to get some feedback/criticism before I begin operating it regularly.

    So as I said they where nothing to worry about as what is in the fault report has nothing to do with how it is running, they probably where from the factory testing and where never cleared, you have to be careful what you mess with

    PD003=400 not 120 ( Main Frequency )

    PD007=20

    PD014= is adjustable normally can get them down to around 3s to 6s without a fault

    PD015= is adjustable the same as well

    PD174= ??? ( To Be Set to the VFD Drives Max Rated Output Amps )

    The temperature on the outside is not an indication of the temperature on the inside the water does a good job most of the time though, have the water run longer when the spindle turns off

    Do you have the Ground wire 4th Pin in the spindle connected this is a must to check that it is Grounded to the body of the spindle

    Re: Huangyang 2.2kw VFD pd177-180 Errors

    @mactec54 Thanks!

    PD174 = 11 (Factory default - VFD is rated at 11 amps)

    PD003 sets Speed 1 when in digital operator mode (PD002 = 0) otherwise in external control mode (PD002 = 1) Speed 1 is set by the analog input, in my case the potentiometer on the VFD. Currently, this setting is irrelevant. I set 120 on the initial run, but then switched to analog mode.

    PD007 Can you help understand this parameter, I've yet to quite nail it down.

    PD014 & PD015 Good to know! I have yet to fine tune these.

    Grounding the spindle (4th pin) was the first thing I did. My tests revealed it was not grounded...

    Water cooling - good idea, I will definitely run the cooling system for some time after spindle turns off.

    Again, really appreciate your input, thank you.

    Not at all PD003=400 that's the main Frequency that the Pot or the Keypad requires for manual control you can not set this lower than your spindle max Frequency

    PD007=20 is the starting Frequency 20Hz .05 is to low when you have to jump up to 400Hz or the minimum speed at 100Hz

    The setting of main frequency is limited by the maximum operating frequency.

    Re: Huangyang 2.2kw VFD pd177-180 Errors

    PD007 - Thanks!

    PD003 - My particular VFD works the way I described and is explicitly stated in the manual as such, you might be referring to a different VFD. I have verified that my particular VFD functions this way as well. Setting PD002 = 0 and setting PD003 = 100 the spindle will initially spin up to 6000rpm. If I change the frequency using the arrow keys say to 120hz the spindle spins up to 7200rpm. At this point, I can stop the spindle and go and check PD003 and it will now read 120 (as stated in the manual attached here). Changing PD002 = 1 changes the main frequency to the pot - PD003 is no longer used. As such I can leave PD003 at 120, but turn the pot up to 400hz and on run the spindle will spin up to 400hz (24,000rpm) not 120hz. Any changes done to the pot do not affect PD003 setting, in this case it will stay at 120.

    You've been super helpful and I consider all my issues resolved. Thanks again!

    What you are saying is correct but if you use the Keypad only, it must be set at the max main Frequency of your spindle =400Hz to get the max spindle RPM using the Keypad using the remote control bypasses this part of the KeyPad as you are saying it is standard practice to set it to the max from the start

    Same VFD Drive I have done hundreds of them and repaired them also

    I'm not sure we have the same model (HY02D223B) or version (Vr1.000). This is not how mine works. P003 does not prevent max spindle RPM if below 400 (max Hz of spindle) when using the keypad. I'm done here now, but as a courtesy, see below if you're interested in the difference between my VFD and the ones you work on regarding PD003's operation.

    Again, very much appreciate your help!


    This is how PD003 parameter works on the HY02D223B that I have (some of this has already been stated, but for completeness I included it):

    First, PD003 applies to the keypad mode only or as the manual says "digital operator mode". Setting PD002 = 1 changes to "external control multi-speed mode" and PD003 is not used.

    Using the keypad mode only (PD002 = 0), PD003 must be set between PD005(max Hz) and PD011(min Hz) - in my case 400 and 100 respectively. It doesn't matter if PD003 is 100 or 400, you can still get the max spindle rpm (24,000) using the keypad.

    For example, the settings PD002 = 0 (keypad only), PD005 = 400, PD011 = 100, PD003 = 100 will simply result in the spindle running at 100hz (6000 rpm) when RUN is pressed. With these settings, I can change the spindle frequency with the keypad all the way up to 400hz (24,000). When the spindle is stopped PD003 will be set to the frequency that was last set using the keypad (in this example, if stopped at 400 Hz, PD003 would now be set to 400, not 100 anymore). Setting PD003 = 400, instead of 100 initially, has the spindle start up at 400 Hz (24,000) when RUN is pressed.

    With this in mind, I chose to start the spindle on my first run at a conservative speed of 120 (7200 RPM) so that I could monitor things. I did not want to first test the spindle at max RPM!

    To summarize, on my model, setting PD003 below max (400 Hz) does not limit the keypad from getting max RPM. It only sets the initial Speed 1 when run is pressed (as the manual states) and this setting is changed during constant run with the keypad. Therefore the next time you turn on the spindle it will start at the last setting you selected with the keypad.

    Hope that helps!
    Take care.

    I'm afraid your VFD Drive is no different from what anyone else's has, here is how the KeyPad works and needs to be set to memorize the last speed

    You are making it sound like it is different but it is not


    (4) When both UP and DOWN terminals are closed at the same time the frequency will neither increase nor decrease. It is regarded as invalid.

    (5) When the frequency reaches the max operating frequency it will stop increasing.

    (6) When the frequency reaches the min frequency or its lower limit, it will stop decreasing.

    (7) After a power breakdown the set value of PD003 will be memorized instead of the frequency.

    (8) When using the function of UP and DOWN, the keys of the panel are valid. After changing the values it needs to press SET (ENTER) key for confirmation and then the inverter can implement the action. Meanwhile the value will write to PD003, which will be memorized after a power breakdown.

    (9) When keeping pressing UP or DOWN the frequency will increase or decrease rapidly to a point and then increase or decrease at even speed.

    (10) The value changed by UP or DOWN can be set through PD077 for confirmation of whether it should be memorized or not memorized. For details refer to PD077.

    Re: Huangyang 2.2kw VFD pd177-180 Errors

    Thanks again, I'm still trying to properly understand PD003. If my unit is the same, then I'm missing something as what you have said has not matched with my testing or the manual that I got.

    I have a few questions here:

    1. What does this mean? What do you mean by "the frequency" as PD003 is the main frequency when PD002 = 0 (keypad mode).
    Quote Originally Posted by mactec54 View Post

    On my unit, PD003 is always remembered, whether PD077 is set to 0 or 1. After Cutting power or restarting the spindle, PD003 is set to the last frequency set with the keypad - regardless of whether I press SET or not.

    2. I'm not understanding properly how PD003 will prevent the spindle from reaching max RPM. What did you mean by this:
    Quote Originally Posted by mactec54 View Post

    PD003 setting has no impact on whether I can reach max RPM using the keypad only. So I'm not understanding this point.

    3. Are you talking about PD003 limiting RPM when in a different mode? (i.e. "External terminal", PD001 = 1)
    As you've explicitly said above "if you use the Keypad only" PD003 needs to be 400 or the spindle won't reach max RPM. This just isn't the case for me. However, maybe your saying that PD003 conflicts with "External terminal" functions? I don't have an analog output yet for Mach3, so I have not and will not be able to do this for some time.

    I will primarily be using the pot on the VFD in analog mode (PD002 = 1) for the time being. But you worried me a bit with the statement that it is "best practice" to set PD003 to 400, but I've not understood exactly why or what would go wrong if it wasn't set to 400, because just about all of my testing so far has been done with PD003 set to something other than 400 - because I initially set it to 120 and the keypad changes PD003. I don't want to wreck my VFD!

    P.S. Please don't read this in a negative light. I don't want to antagonize you after you've been voluntarily aiding me! I'm only concerned about properly understand my VFD. You are eager to help and I don't want to stop you!

    The manual states very clearly PD003 is the Main Frequency, and needs to be set at the max Frequency that is being used

    What is the reason for this, if there is a power cut the only Parameter that will be active is PD003 so if this is set at 120Hz then your spindle on startup will try and start using 120Hz we all know what happens when these spindle try to start / run on a lower than rated Frequency

    You won't wreck your VFD Drive, but it does happen sometimes but the spindle will certainly be damaged

    There are no negatives with the PD003 being set at the correct Spindle Frequency, but there could be if set at a lower Frequency

    When using remote and not the KeyPad PD003 is not active Only if there is a Power Cut is it then active it will be the only Parameter in memory and will try and start your spindle using this set Frequency

    You set them an forget them don't keep changing them to see if something is going to happen or it will, you are dealing with a very unsophisticated VFD Drive compared to an expensive VFD Drive

    Trying to make these VFD Drives be something they are not, will only end in replacement as many before you have found out

    Re: Huangyang 2.2kw VFD pd177-180 Errors

    Mac.....thanks for enlightening me on the settings of a (my) VFD...…...one statement you did stress and that was NOT to switch the VFD off at the wall socket but on the VFD itself then isolate it at the wall socket when finished.

    In OZ we have earth leakage trip devices on the main power supply box that detects any leakage to earth and immediately trips the breaker in the main house supply cabinet.

    Would this be interpreted as switching the VFD and motor off by the wall switch while the VFD Is still powering the motor?

    At the same time we have had many temporary power outs, some lasting a few seconds, others a hour or more......in South Africa they have power outs practically every day for hours at a time.

    Would I be wise to have a UPS on my wall socket where the VFD is plugged in..... (and my CNC mill and computer)…. to continue a supply until I can switch the VFD off manually?....I have one in my study for my CCTV and desktop computer.

    Re: Huangyang 2.2kw VFD pd177-180 Errors

    Well you've got me quite confused.

    Are you saying that these spindles are damaged when running at slower speeds than max RPM??

    How do you run the spindle at variable speeds without changing its main frequency or as the manual states "operating frequency"? I cannot run the spindle at max RPM and have no plans on doing so. That would require my CNC to feed far faster than it is capable of.

    I have not found where it says PD003 needs to be set to the maximum. My manual says that the "operating frequency" is set by 1 of 3 sources, the digital operator, external terminals, or MODBUS:

    1. PD002 is the "source of the operating frequency". This can be set to the "digital operator" or PD003 (PD002 = 0), "external terminals" (PD002 = 1), or MODBUS (PD002 = 3).
    2. "In the digital operator mode, the inverter will run at the set value of PD003. During running, the operating frequency can be changed by pressing UP or DOWN."
    3. "During multi-speed running, the main frequency is taken as the frequency of Speed 1."
    In multi-speed mode PD003 is taken as Speed 1, speeds 2-16 are set with PD086-PD100
    4. "In external control multi-speed mode, if PD002 is set to 1, i.e. given by an external terminal, Speed 1 will be given by the analog of the external terminal."
    The analog voltage or amps (range set by PD070) determines the operating frequency

    In all 3 modes the "operating frequency" is adjustable during running - intentionally. I cannot find where it says that PD003 must be set to the max frequency of the motor (this is what PD004 is, "This parameter must be set according to the rated frequency" and "do not change the set value of base frequency at will"). Instead, it describes how the VFD runs a variable speed motor and how all three modes adjust the "operating frequency" during running.

    If I'm using a pot in external terminal mode, the operating frequency will be set by the analog input voltage/amps set by PD070. Therefore, even if PD003 is set to 400, the VFD will be operating at the frequency set by the analog input, and if this is less then the max voltage in PD070, it will be less than 400. In my case, I'm never going to just turn the pot to max (5V) and leave it there, because that is too fast for my machine (24,000 RPM) so it will be operating at less than 400 Hz.

    Likewise, in the furture, if I'm using MODBUS, I can set the operating frequency with speeds 1-16, PD086-PD100 and PD003. And each speed will be set a lower frequency than 400, except for maybe Speed 16 which could be the max RPM speed.

    Long story short. I need to be able to run the spindle at less than max RPM. If I cannot do this safely and reliably with this spindle. I need to return it.

    So I'm very grateful for your help! I definitely feel like I'm missing something important here. I apologize if I'm unintentionally frustrating you!

    In OZ we have earth leakage trip devices on the main power supply box that detects any leakage to earth and immediately trips the breaker in the main house supply cabinet.

    Would this be interpreted as switching the VFD and motor off by the wall switch while the VFD Is still powering the motor?

    At the same time we have had many temporary power outs, some lasting a few seconds, others a hour or more......in South Africa they have power outs practically every day for hours at a time.

    Would I be wise to have a UPS on my wall socket where the VFD is plugged in..... (and my CNC mill and computer)…. to continue a supply until I can switch the VFD off manually?....I have one in my study for my CCTV and desktop computer.

    You GFCI is not a switch for turning something On / Off with, it is a safety device, a regular switch at the wall is fine, Plugging a VFD Drive into a live Plug that can cause a spike and take out the front end electronics so when Plugging and Unplugging a VFD drive the supply Power should be Off

    GFCI can present problems when a VFD Drive is used on a Circuit that has this, I don't recommend that you use a circuit that has a GFCI on it, even though that will be code in your country, but saying that if the circuit is rated for the Amps needed then you should not have a problem, the same goes for a UPS I don't recommend anyone use one for a VFD Drives backup Power, it would have to be a monster to be suitable for a VFD Drive and would cost a lot of money

    A VFD Drive is normally used in an industrial setting so this is where some of the problems using VFD Drive start to show when used in residential homes workshops, in the NA the 240v supply does not need a GFCI but the 120v supply does

    With what you are doing with your VFD Drive you won't have any problems 50Hz 60Hz Parameter settings you can't go wrong the only thing I would be concerned with is the GFCI tripping as a VFD Drive can cause Ground faults so just try and see it won't affect your drive because you are only running at low Frequency

    It's only the high Frequency spindle motor 300Hz 400Hz 800Hz Etc that you have to have things setup a little different

    If you get any tripping of the GFCI then the first thing would be to add a EMI Power Filter this will help the Power supply noise and better health for the VFD Drive as well this you would install close to the VFD Drive

    You are able to change the speeds in any mode be cause you are not using any of the drive defaults

    With using the KeyPad only

    Jumper J1 would be in 2-4 position I think this is the part you have not been changing to do a normal Keypad up down arrow use

    PD001=0
    PD002=0

    Then see how the KeyPad works although I don't know all the other Parameters you have changed related to the KeyPad use this should only work with what you have set in PD003

    Can you damage the Spindle Yes if you try starting it on a lower Frequency than what the motor max rated Frequency is, this is the part you are getting lost with PD003 is a Main Parameter and if your drive tried to start on the 120Hz then you spindle could be damaged


    As long as the main VFD Drive Parameters are set you can run at any speed in the range the spindle can use

    You have already set the minimum and maximin Frequency and the motor spec's

    PD005=400 Max
    PD011=120 Min

    Re: Huangyang 2.2kw VFD pd177-180 Errors

    Ah Ha....so it's a spark at the wall switch that you have to prevent by NOT hot plugging in or out a plug...….never done that, and it would be difficult as our plugs really stick in the wall socket tight, and it's highly dangerous too for breaking a circuit.

    On the UPS path, the one I have, which is quite modest, is rated to supply for 1 hour 220 volts at 10 amps, so if the VFD needs backing up that would do the trick plenty well.....the motor for the VFD is only 3/4 HP 3 phase......probably 4 amps at most.

    We do on occasion get mains spikes from someone switching a heavy load on somewhere down the line, and sometimes the Earth trip does trip out for no apparent reason.

    They are fitted as part of the mains supply safety requirement and will trip at 10 Ma leakage to earth .....you can't disable it even if you wanted to.

    BTW, on the PD003 VFD thing......reading about the varying speed control in the last post I though the speed was controlled by the round knob on the front....at least mine does...….I won't get into that discussion, just watching to see the outcome.
