Subject : VEC500-controlled motor sudden stop
Hey guys,
I'm new to this forum, and I have a project where I'm supposed to test a BLDC 48V/10Kw motor on a test bench before integrating it in a tricycle. There is :
-HPM48-10000
-VEC500 controller
-PI-400 adapter (in case there might be some configration needed)
-FSC-010 foot throttle (used as a manual throttle)
So, I've noticed that an error occures in two particular instances :
-To give an example for the first case, let's say that I rotated suddenly the throttle to a certain position that produces 2V in its output (range from 0.2 to 4.8 V), the motor turns for a second and then turns off. I've measured the throttle voltage in this instance, and I've noticed that it returns to the minimal value (0.2), and then back to 2V. Here, the controller blinks 14 times, which is from my observations an error given when there's a throttle input(2V, in this case) given initially, as the controller is kind of "reset".
-The second case is when I apply torque to the motor on the bench : The bench is designed in a way that applies discontinuous torque (in 10% steps), for example :
+At speed 1000rpm, I can apply up to 60% of the maximum torque, and the motor turns off. The same thing happens for the throttle input as the first case, it returns to its minimum value, the motor turns off, and the input goes back to the previously applied voltage, which gives the 14 blinks error.
+At speed 4000rpm, I can only apply 10-20% of the max torque before the motor turns off.
My assumption is that in the first case, there's some acceleration time configuration that turns off the controller when I change the throttle fast, or the issue could be in the throttle itself. But in the second case, I'm not so certain.
If the issue includes some configuration of the controller, then I'd like to mention that I can't connect my PC with the controller using the PI-400 cable and the PI-800 software.
I'd appreciate any kind of help, I'm on a time limit to get this thing functioning and I'm really blocked currently.
PS: In the picture : You can find the behvaior of the throttle voltage, I started with a low speed, then I changed the throttle suddenly to a higher speed (equivalent to around 4.5 V), you can see that the voltage is down to its minimal value, which turns off the motor, and returns back to its initial value, which makes the controller blink 14 times.
