Magic Pie & Smart Pie Discussions / Magc Pie 5 error Eb5
« Last post by Soetie on April 05, 2025, 08:03:49 PM »
My bike with a Magic Pie 5 gives an error and don’t response on the thump throttle and pedal sensor. I have search for the error but couldn’t find it. Is there anyone known with this error and know how to solve?

Thanks in advance!

Thanks for allowing me in. I have just had a 10kw motor fitted to my boat, powered by 314ah 48v lifepo4. Add an EZkontroller and a TRC012 throttle. And that's where the problems began.
Downloaded the app to program the throttle. Followed the video I found for a the TRC010 throttle. Updated the app and the motor started spinning backwards. Panicked, pressed a"disable" button on the app. Motor didn't stop so I turned it off with the key and then had to wait around 3 hours before I could get the app to do anything. It kept saying "state motor error" (or something along those lines) which was a result of changing a setting whilst the motor was spinning.
I spent the free time talking to a couple of people who know more than I do and searching for any information I could find about the throttle and what the error message meant. There's literally nothing useful on the web about the throttle. I found state motor error (may have that wrong) but no instructions on how to make it go away.
eventually I got the app working and was able to press the same button and enable the "throttle reset enable" setting. Turned the controller back on and the motor started spinning again. 
So I gave up and went home.
Got a manual for the throttle that evening from a friend, it didn't come with one. Saw that there was supposed to be a safety key. Hurrah. Problem solved,
Nope.
returned to the boat, armed with the throttle and controller manuals, found the safety key, pulled every plug out and started over. The engineer who had connected everything had made a total bollocks of it. Thought Id got everything connected, switched it all on. Nothing.
Made a 5v power supply to feed the throttle. Nothing.
Took the cover off the throttle to find the white cable had been cut and wasn't connected. Confirmed it had 5v on it, took the throttle to an electronics specialist for repair.
No joy from goldenmotor but they will be getting a bill for the repair.
The TRC012 manual has been attached for anyone who wants it.

Hi, I've got the same issue and was wondering how you solved it?

Which throttle are you using ?

Update: so far, I've been able to confirm that the reverse button does indeed swap direction of motion even with a hyperbolic throttle, provided I go to neutral first (makes sense).

When I short the regen brake button, regardless of spin direction, the motor stops quickly and I get the 17 beep alarm that I'd expect when regen is on (as seen on other posts). Whether this actually recharges the batteries or not remains to be seen, as the motor isn't yet connected to the propeller, nor indeed is the boat in the water yet.

Is there any way I can find out about the answer to these?

I don't know if the motor actually produces the same amount of power in Reverse as it does in the default Forward direction, and I don't know how/if the Reverse switch function will affect the motor operation when the Hyperbola throttle mode (Boat throttle with Forward-Neutral-Reverse operation) is being used.

You could simply try fitting a Reverse switch and see if it has any effect on the motor's direction and/or rpm.

Electric Boat Conversions / Regen with reverse switch on but going forward
« Last post by Alpegu on March 26, 2025, 08:59:28 PM »
Hi everyone, I'm hoping you can help me with some questions regarding reverse and regen:

I have a GM BLDC 5kW motor and a VEC300 controller on my sailboat. Due to the way the motor sits, the boat goes forward when the motor turns anti-clockwise. Last year, I had a DIY potentiometer throttle that didn't last long, so I've bought a hall-type throttle from Miromax. It seems alright but it can only be installed in such a way that pushing the lever forward delivers a lower signal, ie it sends a reverse signal to the motor.

Now, since this direction of motor rotation is what makes my boat go forward, it seems perfect. But, I won't get any regen as the motor will always be "reversing". I know I can swap the blue and green cables, plus the hall cables, to reverse the default forward direction of the motor, but that would mean that pushing my throttle forward would make the boat go backwards.

My questions:

- How can I keep the throttle in its current position, while still being able to get regen?

- Does shorting the reverse button just swap the direction of movement? If I short the reverse switch, will it just swap which way my boat goes relative to the throttle signal?

- Does the reverse switch even work with a hyperbolic throttle type, where you already reverse by moving the throttle backwards from the midpoint?

- If this is the case, can I short both regen and reverse buttons to "swap" the direction that the controller considers to be forward, allowing regen to take place?
