i downloaded the parameter setup and i see 2 programs. the 116 and the 8 version
Which one do i have to use ?
I am connecting the LVC wires from Gary/Fechter's BMS to the throttle signal and ground. Is there a satisfactory limiting resistor inside your 12 fet and 9 fet controller, or should I put a 1K resistor on the controller side of the connection?
Also, if I set up my Cycle Analyst for current control as shown on page 19 of the Vers 2.2 manual, do I need to make any changes to the aforementioned LVC - resistor connection. They are both in the same throttle signal wire.

first the hubmotor spinned well, silent and correct when my e-scooter was placed on his stand.
When i wanted to drive with it i noticed that it had no torque.
i think i have to change my green and blue phase wires also.
Because i just copy the wires from my old modified controller to the new LYEN didn't matched i think.
And the brake switch doesn't work. first i noticed that the LYEN controller needed a ground sig. for breaking.
so i resoldered it to the + BRAKE and tried it out. Because when i brake i will put out a 15V signal to the controller.
After resoldering this and put it for the test it still won't shut the motor down when breaking.
Does the LYEN controller need a higher positive voltage ? like 72V or higher ?
if so i have to put a relay which will give the voltage from the controller supply to the brake+
tonight i'm gonna switch the green and blue phase wires as the hall wires. hopefully this will work.
MrKang wrote:On the PCB you can see two connections for the brake signal. when i get it it was soldered to the EB- and GND
which indicates when you ground it it will stop. next to the EB- You will see the EB+ padding. This will change it by listening to a positive signal/voltage
just like my other controller this worked fine. Brake signals -or + are both secured by a resistor/diode network before they go to the MCU.
so i don't think i have blown up the circuit yet.
The brake wire in original state is working wel. ..if i hit throttle and connect the gnd with the yellow it shuts down.
But in my situation i only can provide a positive signal because it's linked with my braking lights on the back of the scooter.
I will fix this with a relay which i will trigger when breaking which will shortcut the black and yellow brake line to the controller.
i will fix this tonight and give you an update. also with the phase/hall wire switch
