VEC500 setting configuration

(1/3) > >>

Hi,

My name is Joel im a new member in this forum and im bussy now with my electric car conversion project using 10kw 72v bldc motor and vec500 motor controller. I can acces the contoller using the PI800 software but there are some items in controller parameter setting that confuse me like acceleration rpm/s and deceleration rpm/s for the speed seting, starting phase current, max phase current and max rated current for current setting, rated battery voltage, over voltage protection value, over protection exit, lowest ollowable value, low voltage protection value, low voltage protection exir value,low battery voltage value and throttle zero position to clear under voltage for voltage setting. For those who have some ideas about vec500 controller setting configuration please I need some help.

Thanks,
Joel

Hi Joel andto the forum.

I haven't seen any information regarding programming the VEC500 controller so I suggest you send an email to David at GM China and ask him what the best settings should be for each of those parameters.

Some of the settings should be obvious, like the "Rated Battery Voltage". If you are using a 72V battery then simply select 72V from the drop-down menu.

I suspect that the "Battery Main current" will need to be adjusted to suit the maximum current that your battery can safely supply.

okay thank you Alan for your reply actually I already sent an email to David regarding the correct setting parameter of vec500 but until now I don't have any reply from him.By the way do you have any idea about this two set of wire harness for the foot throttle? because what I am using now is the set with 3 wires an I connect it to the controller but how about this remaining set with two wires in it is it only a spare or I should connect it also to the controller?

Regards,

Joel

Hi Joel, I seem to recall that some foot throttles also have a switch built in which is often used to prevent the contactor from being energised (and the controller from being powered up) if the throttle is already operated:



This switch could also be used to automatically apply regenerative braking (or electrodynamic braking) when the throttle was fully released.
These functions would require two extra wires, but I cannot see either function being utilised in any of the following diagrams:







I did however find these figures in the VEC Controller Guide:
     Model      Rated Voltage    Rated Current    Max Phase Current    
VEC500-48           48V                 200A                  500A                 
VEC500-72           72V                 150A                  500A                 
VEC500-96           96V                 120A                  450A             

Any chance we can see some pictures and have some more detailed information of your conversion?

Hi Alan,
actually I followed that wiring diagram with contactor that you posted above and there are still wire harness that is not connected yet and one of those is the one in foot throttle but I already made a test run first was not really good because the throttle was responding late and if I will push the throttle in maximum the motor will stop but when it start the motor is performing well I can feel it during the acceleration.This photos are the update of my ev conversion since I left in the Philippine last january and as soon as im back this march I will make some setting adjustment like throttle voltage I already ask David for that current & voltage settings and finalize the wirings connections with utility box.
