EMax Simon Series 12 A ESC
« on: October 16, 2016, 06:54:26 AM »
The manual for this ESC is poorly written, certain sentences are incomprehensible or/and truncated and the crucial information is missing.
Because of that I could not set the brake ON. Factory default setup is BRAKE OFF but this option is listed as programmable. After trying and erring, I managed to enter the programming mode in which option 1 is brake, indicated by one short beep. When this option is selected by bringing the transmitter's throttle stick down to zero RPM immediately after this short beep is heard, there are two choices indicated by distinct beeps: one is short single beep (A), the other has two short beeps (B). Nowhere in the manual is written that (A) means BRAKE OFF so I assumed it by analogy to other ESCs I have. If I was right, the choice (B) means BRAKE ON and I selected it by bringing the throttle stick up, immediately after I heard these two short beeps(B). I could hear the musical tune and this ,according to the manual, means that the choice (they wrote "correspondent value"...) has been saved.

Unfortunately, when I run the tests, there was no sign of brake working in the end of the run. The prop spun many times from set 4,550 RPM to zero RPM so it will windmill in the end of the flight. Manual does not specify the type of brake that can be selected so I do not know what to expect. Hard? Medium? Soft? From experience with different ESC, I know that for soft brake I cannot expect the prop to stop abruptly and, with such brake active, the prop should turn 2-3-4 times and then stop. With my other ESCs, the prop stops after 2-3 revolutions when such brake is ON. I can also feel more resistance to spin the prop by hand after the run ends but the battery is still connected.

EMax Simon Series 12 A ESC is to be installed in one of my control line indoor stunt planes together with EMAX CF2822 motor turning 10x4.7 APC E, KR governor programmed for low RPM and 2S 800 mAh LiPo.

Any suggestions?

Hey Matt,

Your right the instructions are very condensed.  Chinglish, gotta love it.  My take on the instructions it sounds like you programmed it for LOW brake setting (2 short beeps).  Line D2 lists the (6) choices for the brake.  I assume OFF is the first program selection value and HARD would be the sixth program selection (one long and one short beep). 

Step 2 selects the program parameter and step 3 uses the same series of beeps from step 2 to select the actual value to be programmed.

Try that.  There is always the programming card option.

You want to be able to feel some resistance to the prop rotation at the end of the run.

Hi Paul,
When I enter the programming mode and select the option one [Step 2: Select program parameters - 1. "Beep- (a short sound) that indicates the Brake type], I do not have six choices regarding the brake setup - I have only two.
Like I wrote, these choices are one short beep and two short beeps.

Programming card does not work with this particular ESC - the user must use the transmitter/receiver method.

Please note that SimonK Series ESC differs from Simon Series ESC.
I have the Simon Series ESC that, according to the Simon Series manual, has only two brake choices - probably OFF and ON.
I wrote "probably" as the manual does not say that one short beep is OFF and two short beeps is ON. Either somebody writing the manual forgot about it or assumed that moderately literate user will figure it out by analogy to other ESCs. 

Now back to the basement to program, re-program, test and so on.

Why do you want the brake on with an indoor C/L plane?  It's not like these have a great glide or anything.

Because I like to check if our Chinese Friends are providing a reliable product information or just selling whatever can be sold to "stupid white men".

I know this might sound silly, but go back to your BRAKE programming selection and use the FIRST beep after you enter the BRAKE selection to turn it on.

I do not know if you tried this setting or not,so I hope it does work for you. I know that you said that the ESC comes with the brake set to OFF.

It sounds like your ESC has probably the same sort of programming that the old Suppo esc's use to have about 6-5 yrs. ago. Theirs used to be the first beep turned the brake on and the second set of beeps turned it off.

If that does not work, then I would suggest in getting a Hobbywing FlyFun 12A esc and programming card.

Simon K is updated firmware, you should be able to find manuals online for that.
You could also check to see if you can flash with BLheli, which would let you set all the options with a PC interface.

Some info here, looks like with Simon K bootloader you should be able to do programming via the servo wire
