TMCC Motor Driver Question

Do you mean the Odyssey speed controller board 3 wire input?

Rod

Hey Rod

Yes three wires from the controller to the motor sender connection. 

I have never tried running one with the speed control wires disconnected, but it shouldn't cause any problems. Except that if the board is looking for speed control input and sees none, it may drive the motor way fast. Not sure.

If you try this be ready to kill the power ASAP.

GGG or someone else may know exactly what would happen.

Rod

I don't think so.  You can try, but it may default to full throttle.  ERR has the modular board that doesn't require a tach.  G

Hey GGG

Yep that's what happens.  I have a 691-DCDE-B I can change out but need the 4 wire connector plug and wires.  How's your inventory?

I do have some of those.  E-mail is in my profile.  G

Good Evening G

Sounds like a path forward.

I believe that board, the 691-DCDE-B, is the ERR Cruise Commander, sure looks like one.

Good Morning GRJ!

That board uses back EMF for control.  The plug I need is coming from GGG

Yep, that's the Cruise Commander, they've started using some of the ERR boards in products.  Why not, they work very well in upgrades.

I don't think it is.  That is a board from an engine in 2009 time frame where they used it.  ODY is still the standard.  G

GGG, you're free to believe whatever you like, but the 691-DCDE-B01 is the EXACT same layout as the Cruise Commander M.  I hardly think that's a coincidence.  Every component is in the same place, pretty hard to imagine that happened by accident.

It may have slightly different firmware, as one is S00 and the CCM I have in my hand is S01.

I called and asked about it.  So again, it is not the ERR board and there are differences in firm ware and features.  Lionel had one or 2 engines that used this board.  Declaring it is the same by looks isn't appropriate.  They have 4 prior models that aren't even available.  I am sure it will work, but the story is there are differences.  

How can you declare it is the ERR board and Lionel is using them in production?  Is that fact or supposition?   The engine I found it with is a 2009 vintage I believe. G

The 691-DCDE is a Cruise Commander!  The code varies a bit, but very minor.  Much of the ElectricRR tech ended up in the Lionel product line, as the tech came with me to Lionel.

Jon,  I stand corrected.  When I asked I was told it was different and only used in few engines.  How many Lionel Engines are using this?  Does it work as a replacement for an Ody board? 

Since the Technician course hasn't been held in 3 years, could you put together a Engineering course and teach what is going on with the tech.  Things like what are all the different firmwares for, why so many different DCDR models, what the various outputs are,  etc....  G

This isn't the first board I've seen in a production Lionel product, the MiniCommander 2 is used in the Amtrak HHP-8.  The RailSounds Commander also has a Lionel part number and is obviously used in one or more products.

It is interesting, the boards are black not green and there are far more software versions on Lionel website.  I wasn't disputing it was based off the Technology.  But I was told there are differences (not the exact product).  If there isn't any significant differences the Lionel parts are cheaper by $15 to $20.  I thought Lionel had those Legacy RS Lite boards first, and now ERR is selling versions.

Sure would be nice to get a posting of what the various software differences are both in Drive boards, Sound Boards, etc....  G

Lionel boards all seem to be black now a days even the smoke.  Only the very early ACDR and DCDR where green.  I was mentioning Legacy Lite preceded the RS Commander.  ERR new RS Commander boards look like the Legacy Lites with a few less connectors.  I agree Back EMF seems to have been ERR design.

Lionel has about 7 or 8 Mini CDR like boards with various revisions.  If you use RCDR as a search they all pop up.  IF you do 691DCD you go insane trying to figure out why all those different variations where needed for a DC motor.  

As a note, a few years ago, if you typed a part number in, every engine that used that part would pop up.  That has been suppressed now.  It was a handy tool for figuring out what a part was used for, and then cross search the wiring diagram from the service manual website.  Wish Lionel would allow the search engine to do that. G

In the case of the HHP-8, I had the MiniCommander 2 in stock and it was the exact replacement and worked properly, so it was an easy decision.

For the RailSounds Commander, I was talking about the previous one that was developed by ERR.  This Lionel product looks a lot like it.
