Programming with discharged pack

[dwelzel]

When you program (mode 4), do you need to make sure the packs are fully charged? I figured yes because how would it differentiate say a 12s from a 14s pack.

To program modes All you need is enough to run the BEC...

If you can set the modes you have sufficient voltage.

Someone may chime in and claim that to program mode 4 you need a full pack, it's not true,

[Andy from Sandy]

Mode 4 is a self learning governor mode at switch on every time. This is why it is reasonable to set the blades to put as little load on the system during spool up to limit the voltage drop in the packs.

Can't remember mode number but one of them is a learn once governor mode that after it has spooled up for the first time will try an replicate that everytime it starts up. If you spool up with a 14S pack then you would for proper operation have to use 14S packs all the time until you reset and reprogram the ESC. Or at least that would seem reasonable to me.

As stated in previous post this has nothing to do with actually programming it.

True, mode 6 I think, Governor store mode,

Using your weakest battery fully charged, You want to spool up all the way the way (using a flat throttle curve that gives you the he Headspeed you want)first time you spool up after setting it.

Mode 4 is not store mode...

Referring to Page 21), Section 7.4(Mode 4), of my Kos 200HV manual...

It specifically states that one can't program Mode 4 with a 10S batt. and then run a 12S batt. afterwards....among other things.

So, if one uses a batt. that is "discharged".....rather than a fully charged batt.....for Mode 4 programming......that is kinda similar to the 10S/12S warning in Section 7.4 to a certain degree.

So why is it not true?

Thanks

Note that the governor modes on the Kosmic and jive/helijive are different.
Unlike the jive/helijive, the kosmic ONLY has governor store mode.

Mode 4 on a kosmic sets governor store mode.

For a kosmic, it is true that the governor in mode 4 is like mode 6 on a helijive.

However, for both series of ESCs, in governor store the voltage is not recorded during mode programming. What is memorized is RPM and throttle setting, and its memorized in the first spool up, and so yes its true that the first spool up on a kosmic after setting mode 4 on a kosmic or mode 6 ona. Helijive must be done with the battery fully charged, and you must spool up all the way, else an incorrect rpm for the throttle percentage will be recorded.

This is why on the next spool up after setting governor store mode you are advised to use your weakest battery, Because the rpm/throttle setting delivered by that battery will be the data that is recorded. That way your weakest battery will give you the target performance, as will the batteries that you use that are stronger than the weakest battery,

The programming of modes, and the recording of data for governor store are two distinct operations and occur at two different times. The data for governor store mode is recoded during the first spool up AFTER the setting of governor store mode.

After that first spool up, indeed, you DO need to use the same cell count and it is best to use fully charged batteries,

Whether programming governor store mode on jive or helijive it is true that all you need is a battery that can run the BEC. The minimum requirements for running the BEC are different for jive and kosmic. 12 volts for a jive/helijive, 20 for a kosmic,

This topic keeps coming up on this forum... Several times in the past few months, its a source of confusion for many,

For additional info Please read this thread where Tom also confirms this ( though in somewhat less detail)

When programming mode 4 on the Kosmik it is not in Govstore by default! it has to be programmed with the progdisc or BT module ,Mode 5 is Govstore for the Helijive!

As stated by magneto this is not true. A kosmik has normal more 4 and a governor store function. It is a perameter added after as mentioned as well.

The rest of the information regarding how voltage is set on spool up is correct.

+1 on the above. Also note gov store on a 'regular' Jive is mode 11. Regarding the manual I've learned to take the english versions of the Kontronik manuals with a pinch of salt. The implied meaning is not always clear.

[taosgraveyard]

My main point is that with either governor mode, and whether with jive , helijive or kosmic, it's not necessary to do the mode programming with anything other than a battery that will run the BEC.

And thanks for the corrections ...

I wish someone would make this issue a sticky, clearly stating it, since confusion about this one thing comes up a couple of times every month

In addtion, I wish Kontronik themselves, would take some time out.....and re-write their manual...to cover these issues.....putting and end to a variety of speculations.

This is what we consumers expect from such a high-quality product.

It's not the product quality that's in dispute, rather it's the quality of the documents that describe that proper procedure to "program" these ESC's...for our proper operation.

FWIW

[taosgraveyard]

I am in total agreement!!!!!!!

Richard, so what is the correct procedure/procedures?

Thanks

Peeps will still ask on forums, it is EASIER than reading a manual!!! Videos for instant gratification is even better.......

[EEngineer]

I always use a charged pack for programming...

Just want to know what the governor store does and how to program it properly...

And any precautions.
