Hi

I have tried to calibrate ESCs separately,so connected one ESC to motor,PDB and connected it to receiver.When I connected the battery no beep sounds came from the PDB.whether all ESCs should be connected??
 

[Dinesh.fly]

I can not connect the ESC directly to battery because battery has XT60 n ESC has bullet connectors.Please clarify this.

[SK1701]

XT60 is just a 3.5 mm bullet connector in a housing. You could plug it into the battery but you need to be VERY CAREFUL about the polarity and avoiding a  short. Why are you trying to calibrate the ESCs individually? Which flight controller and ESCs are you using? The beeps will not come from the PDB. It will come from the ESC.

Disconnect battery from power distribution board. Then:
1. Turn Tx on
2. Move throttle stick to max
3. Repeat exactly as quoted above.
4. Connect battery to PDB

You will hear a beep (from the motor, not esc or pdb) indicating ESC has understood full throttle position.

5. Reduce throttle to idle.

You will hear another beep. Then the tone indicating the cell count. Then long beep.

Motor should now respond to throttle. Ensure prop removal while doing all this

Had same problem with my new quad kit. Solved as above this Sunday.
Best of luck.

[SK1701]

Iyer Sir, that was my mistake. The beep comes from the motor.
All the ESCs can be calibrated at once depending on the flight controller. Again, removing props is vital.

[Dinesh.fly]

thank u for the reply sirs

its multistar esc with KK 2.1 board..when I connected there was no beep at all.

[Himadri Roy]

Post some pics showing your setup may help others in assisting you!
The beeps will be heard when the kk2.1 is at its home screen(the first thing that shows up when you power up the board....showing voltage Yaw detail,etc...)

[SK1701]

This video may be helpful in setting up your kk 2.1. The ESC calibration is at 4:10 but the rest of the video may be helpful too.

[K K Iyer]

@dinesh.fly,
Did you try the suggestions in reply #3?
Worked for me, so may work for you too.
Beeps on quad are very weak (as there is no fuselage to act as sound box! )

Meanwhile going to see the video in sk1701's post...

[SK1701]

Iyer Sir, when I started off building my quad, having never tackled such a project before, I found the "Quadcopter Build" and the "How To" playlists by this Youtube channel very helpful. It has a somewhat excessive focus on aesthetics IMO but I found it useful nevertheless.

[K K Iyer]

@sk1701,
Best video so far.
Wish i had seen this before last Sunday.
Would have saved me hours of experimentation.
Got my first quad, ST360 from Quadkopters last week.
I am now going to try the settings suggested in the video.
Thanks.

[gunnu]

make sure motor is connected to esc while calibration.. motors beeps not esc..


good luck

[K K Iyer]

We are all commenting, but op is not watching
Gunnu, your point has already been made in this thread

[gunnu]

oops 
i didn't red all the comments.. red only first two ( may b ). hehehe

Iyer Sir, you are most welcome. I am glad to hear that the video helped. How is your quad build going?

@Dinesh, any luck? Is it working out?

[Dinesh.fly]

done like above but no response from motor.

XT60 is just a 3.5 mm bullet connector in a housing. You could plug it into the battery but you need to be VERY CAREFUL about the polarity and avoiding a  short. Why are you trying to calibrate the ESCs individually? Which flight controller and ESCs are you using? The beeps will not come from the PDB. It will come from the ESC.

done like this also but no response again.my doubt is on the battery now..what should be the voltage (individual cell,total) of a fully charged 3s 2200mah lipo?

 

[K K Iyer]

@dinesh.fly,
Subsequent to my earler replies, found that throttle calibration for all motors/ESCs can be done at one go.

1. Turn Tx on and set throttle stick to full.
2. Press and keep holding down button 1 and 4 on KK
3. Connect Rx battery. KK will register full throttle position.
4. Move throttle stick to idle. KK will register idle position

Do not release buttons 1 and 4 till the process is completed.
(You'll need a helper as you'll not be able to connect the battery with one hand... )
Hope this helps.

(Fully charged lipo will show around 4.20v per cell. Different checkers/monitors may show slightly different values in 4.17-4.22v range)

First make sure that the polarity of your ESC's are right then whether you calibrate your esc or not as soon as you plug in the battery you should hear the beep sound from the motor's if not then check your ESC's maybe they have burned out due to wrong polarity.

[Dinesh.fly]

Iyer sir the PDB is not at all getting powered on to calibrate all the ESCs at once.

I've not connected the ESCs in wrong polarity..if the ESC got burnt means any smoke or smell would have come rite?

will the wrong polarity affects ESC??

[K K Iyer]

the PDB is not at all getting powered on

Not clear. There is nothing to get 'powered on' in the PDB. Its only a power distribution board.

Perhaps you meant that the FCB is not getting powered on. This is the KK2.1.

Check if
1. All the wires from the Rx are connected to the FCB with the negative towards the (left) edge so that from the left they are negative, positive, signal.
2. All wires from ESCs are connected to the FCB with the negative towards the (right) edge so that from the left they are signal, positive, negative.

If these are correct, on connecting the battery the FCB should light up with a loud beep and display the version, followed by the 'SAFE' screen.
You have to reach this stage before you can proceed further.

(BTW, the negative wire will be a dark colour like black/grey/brow, positive will be red, signal will be light coloured like white/yellow. Just mentioning this in case you are new to RC)

[Dinesh.fly]

sorry sir I meant the KK board was not powered on..I have plugged only one ESC wire to KK for testing.

[niranjanrao]

You have to connect the ESC to M1 on the KK2.1 only then it will power up.

[Dinesh.fly]

will check by tonight.

[niranjanrao]

This was quite helpful for me:

Your right Mr. Niranjan, everybody don't gets this - one will be panic when they see the KK2 don't power on even if they connect a BEC or ESC to a motor channel - KK2 powers only from the bec connected to M1 pin .

@Dinesh, Try connecting ESC to M1 port, as Niranjan said, if it is still not working, you have to assume something is wrong with KK2.
You can check ESCs by connecting each ESC to throttle channel on receiver.

[K K Iyer]

Dear Sooraj,
Not strictly true.

If you connect a battery to an ESC and connect the ESC lead to the AUX pins (near bottom left corner of the display), with the negative on the left, of course, the KK2.1 WILL come to life!

Thats how i tried it before connecting anything else!

See pic. Main battery disconnected. AUX pin powered via a separate ESC...

[sooraj.palakkad]

Iyer sir, all the receiver I/Ps (4 control channels and AUX) power channel (5V, GND) are connected to this M1 port power . so KK2 will definitely work if you connect a BEC to any receiver I/Ps  - actually we power KK2 in this way if we have all opto ESCs. in that case one might have to connect the BEC to receiver battery I/P - then connect power from receiver to KK2 .

Well for beginners to understand easily - KK2 will power up if you connect a BEC to M1 output or any receiver Inputs - I think that is more clear !!

[K K Iyer]

That is one more step in my learning curve!

[Dinesh.fly]

is there any diagram available how to connect the receiver and ESCs with KK 2.1 board? I have 2 opto n 2 ESC with bec.

[K K Iyer]

Here is the pic from the Hobbyking KK2.1 manual.
Rx cables negatives towards left edge of board.
ESC cables negatives towards right edge of board.

I don't there is any problem in plugging in the ESCs to M1-M4, as long as one ESC with BEC goes to M1
but you should get advise on suitability of using different ESCs

[Dinesh.fly]

sir

my connection is as mentioned below:

M1,M2-ESCs with bec
M3,M4-opto ESCs

connected the receiver input channels throttle,aileron.rudder,elevator through male to male servo lead..now how the receiver will get power?

[Himadri Roy]

Through M1's BEC....flip over the kk u'll see a trace connecting the receiver side!

[K K Iyer]

@dinesh.fly
Sorry i didn't see your post as watching cricket.
Rx will get power like Himadri said.
Just switch on the Tx and connect up battery of quad. Rx should light up.

Pl remove props for next stage of setup. Also ask experienced guys the effect of using 2 different pairs of ESCs

[Himadri Roy]

Very important to remove props just as Iyer Sir said...
Was figuring out a program using arduino to control the motor with the props on and it fired up to full throttle but luckily it was far away from me immediately cut off the power!!!

[xxkrishxx]

is it a problem to use more than 1 esc with bec?

[Himadri Roy]

If you're using switching bec then yes and if its a linear bec then you can
