Vectrix VX2 issue

Post by Monstarr » Jun 06, 2017 4:21 pm

I am trying to upgrade the speed on some guy I know's Vectrix VX2.
Standard speed = 45 kmph. Increasing speed to 50+ leads to a annoying behaviour on the end of the speedrange. It starts dropping speed and increasing speed continuously. Looks like something next to the Sevcon Gen4 size2 controller is overrulling the maxspeed setting.

Long story short...while fine tuning the max rpm point i cycled power several times and the last time it came alive with RPDO fault & IO init error codes in Sevcon DVT which i cannot get erased anymore. I forgot to make a copy of vanilla DCF so i cannot go back to original state :| I know that is stupid.

Anyone here who can help? Perhaps in sending a working DCF file or pointing me in the right direction for a fix?

Update: problem fixed.
I managed to source vanilla DCF for the controller.
Although you need to update the main VX-2's ICM, which does all the thinking, to increase for example the max speed.
The Sevcon seems to be only functioning as amplifier for the motor.
Changing max speed in Sevcon DVT software results in the ICM interfering at the higher set speeds and it drops motorspeed continuously to the max 'original' setting at 45 kmpu and keeps osccilating that way. Needless to say resulting in an unpleasant drive.

Updating the ICM is possible with Vectrix diagnostic software and PEAK can converter. Ixxat converter doesnt work unfortunately.
PEAK converter and diagnostic software are obtainable through:

Hi Monsstar,

Did you increase the speed?
Which files of the diagnostic software ?
45 km/h are really too slow with this scooter.

Best regards

Hi,

You can tweak the max speed slightly with the Sevcon DVT software. Only so much untill the Vectrix ICM parameter limiting kicks in.
If you want radical change in speed or something else you need to alter the firmware on the ICM itself, the Vectrix' controlling print. This is where the scooter keeps her intelligence :)
The Ixxat USB CAN converter which you use for the scooter's Sevcon controller unfortunately doesnt work for the CAN communication to the Vectrix' ICM.
Everything you need (hardware and firmware files) can be obtainable at the Vectrix aftermarket supplier at http://www.shop.vectrixparts.com/
They have excellent support.

Small disclaimer though: increasing speed by firmware possibly changes the scooters license registration and makes it illegal to drive on public roads.
:roll:

Good luck.

Hi monstarr,

I do not want a radical change in speed !!
Only so much to be no obstruction in traffic.
Hard- and software already exists. I am not sure which HEX file to load on the ICM.
Can you help me with that or should I ask Vectricparts?

Best regards

The files needed for speed increase (65 kmu) you can get from them.
I have them too but I cant give any support about it as I never used them before because I dont have the right converter.
I am not sure if you also need to update the Sevcon parameter .dcf file. It got sent to me together with the .hex file so I presume that you also need to upload that file to the sevcon controller.
Filesnames are called:
003439-01-vx2icmwithbootloaderv15.hex
003440-01-VX2 Production Rev4.1.dcf

I did it. :D :D :D
The hex File with the Pickit3 on the icm and everything works.

You did it without the CAN converter?
Can you tell me how ?

You need the CAN converter to see which hex file is on the ICM. This is overwritten with the Pickit3. That's the hex.15 you already have.
