I have a couple of questions. I searched everywhere and can not find a answer.

1) Do I need to change the VFD input to 60hz. it is labeled as a 220/50hz vfd but we run 60 in th US correct?

2) I have the VFD and spindle working but I can only get the RPM screen to 2400 with the freq at 400.

I have my PD3 & 5 settings to 400 and pd144 to 300 as I read here on the forum to do, I also have my motor poles set to 2. The motor is spinning and does not seem to be getting got. Any ideas? I am looking to control with the VFD for now until I am sure everything works well and them Will try to get it to run with MAch3

Set to 60hz, also did you set P144 to the motor rated rpm?
In the manual is states the value of the motor rpm at the set mains frequency. At 60hz would be 3600.

How do you set it to 60hz input?

[Al_The_Man]

PD004 set to 60 (default is 50).

PD004 set to 60 (default is 50).

Isn't that the Base frequency of the motor? Not the input frequency. The manual say PD004 is to be set based on the frequency on the motor''s name plate. Im confused the parameter names don't help much.

[Al_The_Man]

The VFD does not see any input frequency of the supply as the input is to a 3 phase bridge which converts to DC immediately at the supply in.
It needs to know the characteristics of the motor, 2pole 4pole, (base freq) and max and min freq etc.

Al,
Thanks for the explanation, I have searched unsuccessfully for this answer on the web and what was confusing me is there is a memory location to tell you 50 or 60hz input which you can read but not change. So it seemed logically (at least to me) that some setting somewhere else was effecting that readout Seems like our Chinese friends partially implemented a feature. Surprise surprise A few follow up questions: Why would the original poster set PD004 to 60hz if he has a 400hz spindle? Did I miss something? And what does the base frequency tell the inverter anyway?

I think setting the base to 60 means the spindle will see full voltage from 60-400 Hz. This can be very bad at 60 Hz if the spindle is wound for higher frequencies. Setting it to 400 Hz means the VFD will reduce the voltage proportionally with the frequency, and apply full voltage only at 400 Hz (and above, if applicable).

[agitprop]

tahustvedt That make sense, since most pd setups say to set it at 400. That is where mine is set. Still I wonder why they show the option of 50/60 hz if all it does is 50 or it doesn't matter (Which seems to be the case) Seems like a lot of trouble for nothing. But then again i have had stranger "features" on various Chinese products.

Here are the settings you need for your spindle, If your spindle has a Max frequency of 300Hz then you will need to change were the 400Hz is to 300Hz, also the Max amps for your spindle these settings are for the 2.2Kw spindle yours will be the same if it has a Max of 400Hz at 24,000, Just change the Amps at PD142 to suit your spindle

PD001=0 (1 For Remote Control)
PD002=0
PD003=400
PD004=400
PD005=400
PD007=20
PD008=220
PD0011=120 (Minimum Setting 120)
PD009=15
PD0010=8
PD13= 1 is for Factory reset, Only use this to set VFD to Factory Default Settings
PD014 Accel=12 ( Adjust to suit)
PD015 Deccl=12 (Adjust to suit) ( IF PD26=1 Is Used Then the Spindle will Coast to a Stop)
PD141=220 ( Motor Rated Voltage )
PD142=9.5 ( Motor Max Amps) (Set for your motor Amp Rating 2.2Kw Spindle 9.5 Max)
PD143=2 ( Motor Number of Poles)
PD144=3000 (Max Motor RPM) =3,000= (24,000)

Posters please have a better understanding about High Frequency Spindles, 50hz /60hz is not for use with these High Frequency Spindles

When using any of the High Frequency Spindles the 50hz/60Hz, is not part of the Equation, & will damage the Drive if used, (It's called Smoke the Drive Before Getting Started)

The correct parameter settings, for the Frequency is what the Spindle is rated for, Nothing else should be input into the Drive, the Drive Default settings always need to be changed for the Frequency of the spindle being used

Mactec54,
You sound a bit frustrated with us Speaking for myself (and possibly the OP). I am well aware of the differences between the frequency of the mains and a high frequency three phase system. In fact for years, I used 24v battery powered inverter systems that ran two gyros at 400hz. My question was simply why would there be an inverter pd setting reporting 50 or 60hz on the mains which always reports 50. Even when connected its to 60? Was there a pd setting that we are missing? Again, I know the inverter doesn't care because it makes dc out of the single phase power almost immediately. But that begs the question why report it at all? My theory is that the engineers planned to implement some sort of detection circuit of the line freq and it got dropped due to cost.

Very simple, most VFD drives, unless custom made, are set at factory Defaut for either 50Hz or 60Hz depending what country you live in, the reason for this setting 90% of all VFD drive are used in the industry with regular AC 50Hz/60Hz motors,

This is why when people get a VFD the first thing they will see is the default settings, which will be 50Hz or 60Hz

Most drives can handle, if the settings are wrong, the cheap Chinese VFD drive do not survive if you input, or have the wrong settings,I have lost count of how many of these drives I have repaired because of incorrect settings

Just remember what you have connected to the output, is what the VFD has to be set to
