Too of headstock with oil fill plug? Or the rear cover?

I have a spindle 2 v pulley if you need one. If so I can get diameter / bore etc.

Appreciate the confidence you have in my cobbling skills. The AutomationDirect DuraPulse GS3 VFD I bought has a configurable encoder input stage and supports the line driver signal.

Thanks.

Thanks Mike;

I have the manual with that page of info. I remember when reading it there was no mention of signal type. Looking at the picture again though I'm guessing the op-amp symbols in...

Can anyone tell me the type of encoder signal the Yaskawa UAASKA type motors use. I assume its a line drive output signal but cannot find info anywhere.

Thanks for the input. I've read plenty of posts on setting up VFD's but would appreciate anyone's input on 'doing it right'. I have toasted a VFD in the past so am a little gun shy.

A quality...

Forgot to mention in the opening post: This will be driving a Deckel FP machine with 6 speed gearbox. Should have no problem getting all the torque I need.

I have a Yaskawa UAASKA-06CA1 spindle motor I need to control. The nameplate current is rated at 29A continuous and 39A for 30 minutes. The actual power rating of the motor is 3.7kw cont and 5.5kw...

Evaporust! Excellent rust removal.

Would you please post pictures of the inside of the control cabinet.

I intend to keep the entire drivetrain and gearbox system in place. I will be able to replicate the signals my existing DC spindle driver outputs to the machine controller with the outputs from a...

Everyone should upload hi res pictures of the panels they need fixed with enought dimensions to ensure the picture can be converted to a reproducable file with correct proportions. As stated above...

Should have done my research before asking..... Looks like the concensus is that I should be able to run as low as 5% of rated speed with good cooling and the very low load required for jogging gear...

I am looking to replace my Deckel FP5 Mill spindle motor. The original setup is an ABB/BBC thyristor driven DC motor. I intend to go to a 3phase driven via VFD. My concern is:
Can a VFD be...

Well......... We have a saying in my industry: "Go where the airman was last!" (I work as an avionics technician on Airforce aircraft)
Embarrasing I didn't find this sooner. I am using...

Here is a print from a BBC drive pdf I have:

my control cabinet does not include the two inductors L4 and L5 that are shown in the print.

The field supply itself is simplicity. Just a...

I agree with you except re: the motor. Made by Kessler Group. It is top notch quality. Lot more troubleahooting to do. Your right, I've not found the root of the problem as yet.

Believe I've figured out the problem: Prior to hearing the noise from the motor: There was no power to the field. A few weeks before the problem started I had moved the wire on the R5 resistor...

The 3phase input to the machine is 380ish VAC via a step up transformer from my Phase Perfects 220VAC output.The field supply gets it power from 2 legs of the input.

Thanks for jumping into my mess JST. A volt meter shows 0 VDC and .13VAC on the armeture before you hit the system enable button, after enabling, it is still 0 VDC and jumps to .9 VAC. The field is...

Once the weather improves a bit I am going to get my o-scope on the 12ea. thyristor gate drive signals. I assume there should not be any output signal to any of the gates when the spindle is off. ...

The spindle motor has an integrated fan that is working. The BBC drive does not have a dedicated fan, it is cooled via the fans in the doors of the cabinet.

The embarrasingly obvious thing I have not yet checked is that Im getting all three phases into the BBC itself. Find out tonight.

Well, further troubleshooting and a bit more info. The "growling" noise in the motor also goes away when the field voltage is removed. Guess that makes sense..... Field or armature needs the other...
