What is the new 2.0mm pitch connector used on new version bms?

Re: Alight sin/cos encoder of motenergy motor with SEVCON

Is the second encoder offset set to Zero for Motenergy motors? No offset number is supplied with motor.

Re: how to program a sevcon gen4

P34 is current limited for use with a 2 wire throttle.
I have not done it, but clamp it with a 5v zener and measure current. A few hundred ma is safe for a common 5w 5v.

Re: Pmac tuning

Possible solution.

Put in a known working dcf and I have the same run away. I did not yet change the sw (dld) to known working one.
That seems to point at a dld that controls this function.
Good news I think. Smile

Re: Pmac tuning

Not bad, just not normal. It feels like it's more than coasting. Raining here so I have not been able to test anything. Maybe it's different for pmac. What Secon calls neutral braking in induction motor control, is regen when lifting throttle. Down hill I can often see over 50a charging current. In ...

Re: Pmac tuning

No fix yet, but it's a neutral braking issue. Set to 10% which explains the torque level.
Torque is supplied in the same rotation as drive when breaking.
Timing problem? Or is there a setting for brake torque positive or negative values?

I need neutral braking, vehicle coasts forever without it.

Re: Polaris Ranger EV Sevcon help

Solution for now is using oem Polaris dual throttle. Works perfectly F&R. Why, I have no idea. To use my existing single pot, I used a divide by 2, sending 1/2 voltage to second throttle input. .25v-5v to p23 .12v -2.5v to p22 Defeats the purpose, but runs. Overall a huge success. A Polaris powe...

About 10 of my used gen4 s4 80v are "207".
Will they do the same encoders as my 203s?

Re: Induction motor sevcon gen4 issue

I don't have a ranger, but I have the controller and files. S4 and s6 gen 4 controllers. Also 8kw induction motors and big Pmac motors for transaxle mount.
I was hoping to run higher voltage, but the ranger files from s6 48v won't run in an 80v s6.

Re: Induction motor sevcon gen4 issue

No, it's an induction motor with ab sensor. Same motor and programming works fine in s6. Am I wrong to expect it to work with s4 at lower performance? It may be hitting a hard current limit and clipping. I would expect it to lock out in that case. I'm looking for a way to limit torque at low rpm. It...
