Votol EM-100 & EM-150 controllers

Hi, I’ve read through most if this thread and my brain is frazzled. I have, what I think, is a straight forward question but can’t find an answer.

I’m using a 3kw QSMotor hub with an EM-100 controller for a classic Vespa conversion. I am not using the digital display unit that comes with the EM-100 which has the selection button for the 3-speed modes.

I therefore need to use a separate switch to select between the 3 speed modes.

So my question is hopefully simple. What wires do I need to connect to switch between Economy, Normal and Sport modes?

Fingers crossed for a simple answer and thanks in advance.
 
There are two options.
One is: with a button and each time you press you change gears from 1 to 3.
The other is: programmatic each time the Bosch key is turned on.
It is programmatic: You turn the throttle handle together with the brake and hold them. You turn the ignition key and by means of the button you have (terminal 5 on the socket - picture 1) you change the speeds between 1 and 3. After releasing the brake and the throttle handle and you have selected for example 2 speed it remains and cannot be changed. If you want to change it, use the procedure I described above.
If you do not do the procedure but just turn the key, it starts at the speed you selected by default in the software photo 2

Hi, thanks for your reply but it doesn’t really answer my question.

I understand that the speeds are selectable via a button or a a switch, neither of which I have at this stage. I didn’t know about programmatic option.

I am not using a display so have no button to scroll though the gears. I am planning on fitting a physical 3 way switch to select gears.

So I need to know what what needs to happen electronically to select the 3 gears e.g. connect x coloured cable on x plug to earth to select gear 3/Sport mode

Does this make sense??
 
Pin 15 + 12V = sport gear farbe white
pin 4 +12V = 1 bis 3 gear farbe white/brown


I understand that you do not have a display for this, with the programming you will make all the settings

Thanks for the info. I think I’ve worked out how I can manually switch between the 3 speeds by using the old indicator switch. I didn’t realise that boost is in addition to the 3 speeds however

Final notes about Votol EM-150/2
Bike config: QS205 motor (kv17), 40Ah (20s, 88v max) battery, magura throttle, 1:3.25 reduction ratio, almost 590nm on wheel.
Controller config: 200 bA, 9600 pA, throttle config all 255, FWc 80, FW 2300, SportMode, tc not modified

Good news:
it's not pulling down the power so dramatically as previous one, but still have such a wish)))
throttle and torque parameters are editable now
max speed increases (75+ km/h) in comparation with kelly8430 (55km/h)
idle motor RPM - 2600
doesn't overheating, but phase wires are hot

Bad news:
I was able to reach power loss
really huge amps consumption (like 30A idle)
can't go without FW
strange noise from I don't know

great info, thanks.
for the qs205 motor, this is a hub motor right? did you have to make any modifications to make it a midedrive? using the magura throttle is there any modifications or settings that need to be made with the votol controller? would you use the magura throttle again?
which motor do you prefer with your setup now that you have both (qs 138 mide drive or qs205 kv 17 motor)
 
Hello everyone!
I have search the most topic but cannot find the problem same like my case. Hope anyone can help me to solve the problem. I use em-50 with mid drive motor 48v 1000w for my buggy. My setting is as attached. The problem is when i accelerate (2nd, 3rd gear and sport mode) and release the throtte for a while (no any problem when accelerate).The controller will show fault code 00000002 and overcurrent. But the current in that time is not exceed or even close to the bus bar current limit. I use hand brake to high brake port. Hope someone can help. :)DD2580C4-5E7F-4F14-82D4-2C49297AEAD5.jpeg

I think your motor settings looks a bit odd. -120 degrees? Is it really 4 pole pars and surface mount magnets? I think the fw compensation is only for ipm motors, I think you should try 0 there. Maybe you should turn off HHC and HDC until you have it working as it should.

Thanks J bjork for your suggestion. :)
Actually i dont know exactly for motor specification.
- For -120 degrees, this is the best smooth and no noise when i tried.
- How many pole that you suggest to set in odd?
For fw compensation i already did for 0 and also unmark for HHC and HDC. The problem still the same.
I think about another parameter is EBS that I set to 0%. Is it possible for overcurrent when release the throtte? Another seen when I release the throtte there is no regen signal as well.
 
Well, I have no idea how many pole pares your motor have. But I think 4 sounds low. Others can answer better if it is possible or common. The qs 138 70h has 5, 23 seems common in hub motors. Qs 205 50h has 16. Do you know what motor you have? Maybe someone knows the specifications in that case.

First: is controller in park mode? It’s well described earlier in the thread how to find and fix it.

Can you tell me which answer can solve for park mode? I tried to search but not find and get the answer how to solve. Thanks for your answer in advance.

I got the information for the motor pole. It is 12 poles motor. I change motor pole to 12 poles and the result is the same. I set EBS from 0 to 20% and unmark HHC HDC. The problem still there that when release throtte it will fault by overcurrent. I check the regen by turn the wheels, rpm will show as - and + same as direction of the wheel turn. Regen signal will appear. If anyone can suggest what i have to do. I will most appreciate for that.

I believe that motor has a square bemf and should ideally be driven with square wave controller.
What other phase angles did you try besides -120? That’s your biggest chance of getting it to work to find the optimal phase angle match.

I tried phase angle -180 -120 -60 0 60 120 180. At -120 angle phase, motor can run smooth and no noise. Only problem is when release the throtte (speed slow down but not stop yet). The controller cut off and show overcurrent.
 
larsb said:
That’s too rough steps, you need to be within max 20-30 degrees from optimal for it to work well and ideally max 5-10 degrees.

Do you have cutouts only with noload or also when driving?
Click to expand...
Oh IC. It is cut out both when no load and driving on ground. Any parameter that recommend to adjust?

Usually, 12 magnets is 6 pole pairs. Is the setting asking for number of magnets, or pole pairs?
 
Does anyone know why this is happening pls?

It opened up fine the first time but now seems corrupt. I’ve removed it and re-downloaded but no joy. Could it have something to do with my anti-virus software?

 
Hi,

Just finish my Gokart with Votol EM150SP and QS138.
