So, I am returning to this controller after an 7 month absence. I was well on my way to making a proper manual and getting more of these controllers to test on, however, I was not able to resolve the lightly to unloaded runaway condition when operating at max speed. I intend to go through the...

This happens to me when I have an issue with the motor (like an unloaded runaway) in the Calibration page. You need to power down the controller and remove it from Voltage. Then allow it to discharge for a period of time (at least 10 minutes). What is most likely happening is that the...

I do not know what F, U, and D are, but i have figured out the others through testing. IO sets up the assigned function/wire for Output only, like the hall or RPM line. The SW sets the assigned function/wire for a Jog function, such as a button on a throttle moving from Low to High with a...

You note 1.1, although your HW states 1.13, which is the latest firmware. If that is the case, your software and hardware firmware look up to date. Now, it does not appear that your device is locked, so I assume you can change it to the correct Votol controller and as you note, make any other...

When you log in, what is the Software and Hardware (SW: and HW:) displayed on page 1. From what I have read, there appears to be some incompatible hardware firmware and software out their.

Agreed, however, I think there has been some progress in addressing some config issues and bugs. I think the thread is too large to be useful and should have a new sticky that pulls out some nuggets of wisdom from the bulk (latest program, manual, Low Brake, Throttle off regen, Field Weakening...

I read through it carefully but there is a lot of bad and old information in it. I have tried nearly everything to prevent the run-away, and have not been successful. Nothing works, at least through the observable/programmable fields that I can determine.

I have recently setup and configured the Votol, specifically the EM-100. The software is V3 and the controller is V3 as well. As far as my testing has gone, I have managed to figure almost everything out and it is working well. I have read the 50+ page Votol thread carefully, as that is where...

The motor started its life as a Motenergy ME1016 3000W generator. It was made quite robust, including the 7/8" shaft. As a generator, you would put on a few Pelton water wheels which would produce the needed RPM to produce the AC voltage. As a traction motor, I needed to add hall sensors to...

Basically, I converted this 3000W generator motor to a PMDC sensored brushless motor. The torque is over 60 ft lbs. https://www.ebay.com/itm/Micro-Power-Hydro-PMA-Generator-ME1603-1200-2500-Watts-24-48-VAC-Motenery-Inc/202756623373?hash=item2f353c8c0d:g:AZUAAOSw2XFUiFqF

I will try the field weakening parameters to see what can be done to improve it. I thought it was simply a no load issue, just not sure why it never happened with all the other controllers. I would guess that most only have slight field weakening, while the Votol supports up to 200%. For...

So, I am setting up a Votol EM-100 to understand parameter changes. I am connected to a medium sized PM brushless outrunner motor attached to an aluminum bracket with nothing connected to the output shaft. This configuration has worked fine with many controllers I have tested, however, with...
