Re: K 700 S electrical question

 

Purely anecdotal, but I'd have no concerns with that rotary converter and that saw combination. The saw doesn't have a heavy startup current like, say, a water pump, so startup overamping should be nothing special. Any electrical?device is designed to withstand some intermittent?overamping beyond nameplate. I have used a 10hp American Rotary on an industrial lathe that runs a heavier startup mass compared to a saw blade with sheaves/chucks/stock, and never experiences problems. If you had a smaller rotary converter like a 5hp, I'd bet it would still be okay, but you might find your limits cutting heavy stock sooner. Fortunately with a saw you can make sure your blades are sharp, and you can slow feed rates, and manage amp loads. That said, I'm pretty sure my 700 saw has a 4.0kW?motor, never felt it was lacking in normal use. I wouldn't know what I was missing if my saw had a bigger motor.

Happy hunting for a good machine!

Hey Craig,

Felder should be able to provide the specs for that motor(specifically FLA), and you can shoot that spec to American Rotary for them to confirm. Or, you can do your own homework if you want a faster response. I assume you can find the output spec for your converter pretty easily. I suspect you will be fine, because it takes an unusual operation to max out a 5.5kw motor on a saw. I have maxed out the capacity of the 700 before crosscutting a very thick end grain island, but it's not often you are sawing through 5" of material.?

That seems like a fairly good deal on the used saw. For how lousy the last few years have been for used machine buyers, it appears that things are coming back down to reality. Good luck with the upgrade

Re: Phase Perfect Order

 

Also I found this PDF instruction for installing toroids on the PTE models which seems to go along with the claim that modern PTEs have them.

Our email exchange went as follows:

Sale rep:
Good morning. I see you are curious about our phase converters and how we are going away from that 2nd inductor for ¡°quieting down,¡± of the units. The toroid design is going to eventually be across all of them.
Me:
Hi Daniel,
I will likely need a 15 HP 240v single -> 3 phase converter in a few months. It looks like currently only the PTE line has a 15HP 240v model. Does this model already have the newer toroidal design that reduces noise?

Sales rep:
The PTE¡¯s have toroids, yes they are much quieter.

Thanks Larry. Do you happen to remember the name of the sales rep you talked to?
Re: Phase Perfect Order

 

I talked to a phase perfect rep today and got some more info related to the quiet models.

He confirmed that all of the "quiet mode" add-ons and current design of the bigger phase perfect models are being replaced with the new toroid design.

What I found interesting though was that he said the current PTE models already have the new toroid design and are much quieter.

He didn't say whenever this change got implemented to the enterprise models, so I don't have a good frame of reference to ask about opinions from folks who bought them in recent years. But apparently if you buy enterprise today, you will get what they consider to be their new quiet technology.

Hi Brian,

For my machine a single ground wire needs added to bypass the brake board. That is, if the brake board is removed this wire needs to be added to run my machine.

Check your schematic it should show a dotted line with verbiage of Ohne Bremse or something Bremse.

As for repairing, it is easy to detect when a part is cracked open although no guarantees that something else that visually looks okay isn¡¯t bad.

I can take a pic of the new board installed in the KF it is still about 20 Yrs old because brake board failed rather early in the life of the machine. I remember it being identical.

I am still curious about the diode on the back side of your board. Are you the original owner? You can also compare your board to mine to see if a diode is missing from topside and it was easier to place it on the bottom due to tall components each side.

I did do a quick check and the vias used to solder the diode on the back side do not have a diode on the top side on my board. However, it might still be connected between the same electrical nodes as one on the top side.

There is a repair shop I use to repair large (40 amp) electronic dimming modules that fail at about 20 years due to capacitors aging out. Drawback is they take a long time to get to it. Do you think the saw will run if I remove the board to have it repaired? Or is there an easy way to jump around it?
I've sent this info to FelderHQ in Austria.

Re: Failed engine brake 220v single phase C3-31

 

Irman,
do you by chance have a photo of the new board you got from Felder? If it's no go with Felder I might have to track it down from somewhere else. I spoke to the manufacturer of the old board and they we very responsive but couldn't help.

Brian,

Your brake board is same as one in my 2002 KF700 (pcb p/n match). My KF is 3 phase with 3KW motors. So not same as the brake board I mentioned in the Hammer machines.

I assume the sticker on top side identifies the populated board p/n. The pic below shows the sticker on my original brake board.

image0.jpeg

This is the original board (that I repaired and keep as a spare) does not have the diode installed on the back side. I don¡¯t recall if the new board that I received from Felder has that. Will need to open the machine to check.

On this board the capacitor in location pointed by arrow (brick red with blue sticker on your board) had failed. There is a sense resistor (hanging in air on right of the capacitor that is worth checking. I replaced mine just in case.

Hope this helps in some way.

There is a local electronic repair company that could look at this, they repair vintage equipment, but have a long lead time. I don't know if the machine will run with this removed or how to wire around it.
There is no fuse.

Ed,

I actually picked a pre-configured bundle that they had ordered for the AWFS promotion and it is supposed to arrive around October this year.

Unfortunately it doesn't have the fence quick locks (at least I don't see it on the itemized quote), but it does have pretty much everything else that I would have picked for a custom build.
