Programming the Vector Controller
ToddMurray:
I've had my MP vector rear hub installed for about a day now.
Some minor issues running on 48V 10A Life battery however. After a full charge, the controller will not engage the motor.
If I wait a few minutes, pull the plug off the battery, then connect it again, this seems to resolve the issue.???
Once the battery runs down a bit, I can't reproduce the problem, until I recharge the battery. I checked the voltage on the battery after a full charge and it is 58.3V. I'm using the 3Amp charger.
On to the road test.
I'm getting about 43Km/h with a mountain bike on level ground with no peddling. This was confirmed by the street radar sign in my neighborhood.
I tried it tonight on the steepest hills I could fine and I never needed to touch the peddles to get up.
I have the twist throttle. I find it twitchy, especially on bumpy dirt trails. I discovered if I put cruse control on at a safe speed, this helps the jerking on the throttle.
I also check the max amp draw from the battery, and it peaks at 25Amps.
My hub is on the rear with a rear battery mount. This leaves my front end very light. This is not a problem on the paved roads, but I get really loose on dirt, and I must really slow down.
I'd like to bring this down to 32Km/h but can't get the MP3 application to work with the MP vector. Can someone point me to the correct application to use for the Vector?
goldenmotor.ca doesn't have it listed.

Hi Todd,
It sounds like you "Overvoltage protection value" may be set slightly too low as it should not deactivate the controller until the battery voltage exceeds 62V for the 48V battery:
Regarding the programming problem, I did reply to your post over on ES but presumably you haven't seen the reply, so I am reposting the important bits here:
The driver and programming software that I used with both Windows 7 and XP can be accessed here:
CH341SER.EXE USB driver
PI-800 version 3.3.0
You can download my "Torque and Speed" spreadsheet attached to this post which should come in handy for working out the required wheel rpm to set your maximum speed (see the lower left hand section). It will be interesting to see just how accurate the real rpm is compared to the programmed rpm (and your maximum speed).
First you’ll need to install the correct driver for the USB lead (download and run CH341SER.EXE USB driver in the above link) and download the programming software (LBMC_GUI_v3.3.0_GoldenMotor.exe in the above link).
Here is the important sequence that must be followed in order to connect successfully:
1) Connect the USB lead. (Vector controllers use a USB lead fitted with a five pin connector, see below)
2) Open the software that you downloaded previously.
3) Select the correct COM port from the dropdown option box (if you don’t know which COM port the USB lead is assigned to you will have to repeat the whole process selecting a different port each time until you find the right one).
4) Click the “Connect” icon and wait for the timeout error.
5) Then connect the battery power!!
The controller should instantly connect and the relevant parameters should automatically be uploaded and displayed.
When the alterations have been saved to the controller you need to unplug the USB lead and then switch the battery power off and then back on again for the controller to work.
If you switch the power off and on again without disconnecting the USB lead it will re-enter programming mode again.
Please let me know if this works for you.

Thanks you so much.
I will give this a try and updated this thread.

Hi Alan
I can't get this CH341SER.exe driver to work. I installed it as administrator.
I tried it on two Windows 7 computers. One is 64bit, the other is 32bit.
I would expect once the driver is installed and USB cable connected, the new com port would appear under Computer Management, Ports (Com & LPT).
I have a USB to Serial Port on Com7, but that is for something else.
The Vector USB cable is not showing up on a port.
I did try your process of running through all the com ports, but that didn't work either. Probably because there com port was not added by the driver.
Please advise.
Todd
ToddMurray:
After a little reading about this driver, it works for chipsets CH340/CH341.
I have apparently been shipped the USB Programming Cable for Vector Controllers SKU: VEC-USB.
Does this USB cable have this chipset?
