Thread: Wiring VFD to Arboga mill?

Hi Ken,

I've changed my mind... (happens all the time)

The VFD capacitors discharge time with the motor on, probably allows you enough power to do something close to Category 2A stop. (Thanks Keith for the refresher)

When you hit the e-stop, a relay supplies the stop signal to the drive (which ever one of the stop inputs is faster) and drops the latching (isolating) contactor at the same time. The available power in the capacitors can then be applied to stopping the mill.

Regards

You misinterpreted my comments in post 5.
I was talking about myself, not you.
i.e. "Well thats a first" that I beat anyone. I believe I am right is saying that I am well known for typing messages extremely slowly so tend to have message over lap. The fact that I beat anyone would be a first.

Stuart

Ok Kiddies, now that we have most of who said what and to whom sorted out lets get back on topic with reasoned debate.

Then I apoligise.

Cool, can you please undelete the original post 4 for me?

Thanks.

Ok. Ignore PM. Blind today.

Np These things happen.

The photos I said I would get.

This controller is for a big pedestal lathe on the back veranda of my shed.

The veranda is open at one end so I recycled an old aluminium trunk to house the controls. ( a metal tool box would do to.)

The case is grounded & has a good solid ground wire to the lid as well.

The power to the box comes out of the shed wall from behind.

The remote control panel is on a good shielded data (DC control) cable that can be positioned near the operator or rolled up & stored in the box when not in use.

The control lead will run directly from the VFD to the remote panel so the door has to be open while it is running, this also means that the VFD can get fresh air for cooling.
The VFD has a heat sink & a fan & I have bolted it to a good thick aluminium case to give it more heat sink.

The drive cable to the motor (not connected in this photo) will come up through a gland in the bottom of the box.

When not in use, the whole lot can be closed up to keep geckos, ants & mud wasps out.
I also have the manual & all the specs sheets & programming notes stored in the same box.

What on earth does all this mean? It's an extract from my Teco manual.

1. Fn_19, Fn_20 =1 : JOG
2. Fn_19, Fn_20 =2: Sp1 terminal
3. Fn_19, Fn_20 =3: External emergency stop signal
When the external emergency stop signal is activated, the inverter proceed a decelerate stop
(ignoring setting in Fn_14). Flash E.S. after stop. After the emergency stop signal is deactivated,
turn the RUN switch OFF and then ON again.(Fn_10 =1) Or, push the RUN key (Fn_10=0). The
inverter will then resume operation and restart. If the emergency stop signal is removed before
MiniCon stops, MiniCon will still execute emergency stop.
4. Fn_19, Fn_20 =4: External Base Block ( immediate shut off )
When the external base block signal is activated, the inverter output will be immediately shut off
(ignoring setting in Fn_14) and flash b.b. After the base block signal deactivated, turn the RUN
switch OFF and then ON again (Fn_10 = 1) or push the RUN key (Fn_10=0), the inverter will
restart from the starting frequency.
5. Fn_19, Fn_20 = 5: Reset when inverter fault.

It mentions when the external emergency stop signal is activated. To me this is meaningless, where does the emergency stop switch go, there is no wiring diagram.

Hi Ken

Terminals "SP1" and "RST" are "muti-function inputs"
Depending on the settings of F_19 and F_20 gives you different results when either circuit is activated.
If either is set to "1" then that terminal when activated will jog at the FREQ set by F_09
If either is set to "3" then that terminal when activated!! acts an and E/stop(not when deactivated like most E/stops)
If either is set to "4" then that terminal when activated acts External Base Block(something on this setting I will check on my VSD)
If either is set to "5" then that terminal when activated is auto reset

If F_19=2 & F_20=6 the you can have three jog speeds the FREQ set by F_08, F_26 and F_27
(tables for this are one page 39)
F19=6 & F20=2 is pretty much the same thing the switching is just a little different(the second table on page 39.

F_14 is the setting for either controlled deceleration stop(0), free run stop(1). If this is set to free run stop(1) it is ignored and controlled deceleration stop(0) is used.

The wiring diagram on page 5 shows it terminals 6 and 7. Either terminal or both can be used for E/stop(assuming F19 and F20 are set correctly)

Hope this makes sense.
The offer to come have a look at mine is still open if you think it will help, but mine may confuse you even more.

Stuart

Thanks Cliff & Stu.

Struth, so many choices. I just thought wire it up, and Bob's your uncle. I'll have to print out your instructions, and keep aside for when the time comes. Stu, you mention the wiring diagram on page 5. I don't have a diagram on page 5, however there is an overall diagram on page 15. I can't read my postage stamp sized manual, and am using a pdf download from Teco.

My manual face page says Teco T-verter E2 series.

Stu, I will pop over when the time is closer.

Ken

Typo, 15 it is.
Just to make sure we have the same manual, check the bottom right corner of the last page of our pdf. Ver:11 2010.04?


Stuart

Hi Stu,

Nope, my last pdf page contains a parameters table for the customer to fill in.

There's nothing else printed on the page, however, I'm sure we are on the same page.

Ken

Well thats one version I dont have. lol (you seem to be missing the last two pages)
I have three versions, one that came with the unit(Ver 9), one from the Aus Teco site(Ver 10), one from a Teco site overseas(Ver 11). lol
But they do seem pretty much the same.
Stuart

Hi Ken,
I have drawn up a Circuit Diagram useing a simple Latching Contactor for the Emergency Stop, Relay and Rotary Switch for Start/Stop and Forward/Reverse.
The Speed Selector Switch is for the Two separate Motor speed windings and should not be switched while VSD is working on one of the Motor Speed Windings.
Cliff and Stuart have given advice on the Function Settings.

Regards,
Keith.
