Hi,
Hoping someone may be able to Help. ~ Thanks Amberwolf for helping re the placement.
Am building up a bike, have a 36V 750W front mount brushless NON geared wheel, a KT-LCD display linked to a KT36ZWSL-LCD controller with PAS sensor connected.
Firstly, I do not know what brand or model number the motor is, but it has 51 rotor coils and 46 magnets and as I said is a direct drive unit, Black in colour with three alloy or silver radial bands on each side of the motor housing.
Everything initially seemed to work OK with the exception of the PAS. The motor drives irrespective of wether I am pedaling or not. My understanding of PAS is as follows. Please feel free to correct me if I am wrong in my understanding.
PAS as I understand it.
True PAS as specified by the current Australian legislation is that the motor will not start until you start to pedal. In true PAS mode the throttle is not used, but the motor helps out up to 25Km/Hr where it cuts out. Apparently you can select on the KT-LCD a PAS assist level, 1 through to 5 which will determine how much help you get from the motor.
In Non PAS mode, the throttle determines how fast the motor runs. You can pedal if you wish, but don't have to.
The current Australian legislation also states that bikes can only be legally ridden on public roads is they have a maximum power of 200W (non PAS), or if set to true PAS they can be 250W.
Question 1.
Is it possible to go into the advanced settings of the KT-LCD and change from pure PAS to Non PAS mode as required?
Question 2.
What do I have to do to set up true PAS mode on the KT-LCD?
I have gone into the advanced settings of the KT-LCD and changed P3 to 1, but still no luck in disabling the throttle and setting up the true PAS mode.
While I was there I noticed that P1 is set to 46, P2 to 0, P3 was initially set to 0, P4 is 0, and P5 is 12.
From what I have read, PI = alinico rotar number * reduction ratio and its default is 86. Question, what is the reduction number? assuming a direct drive motor am I correct in assuming that it is equal to 1 and as I have 46 magnets P1 is correctly set at 46.
P2 (currently set to 0) seems to be a motor speed sensor factor. The number of pulses per revolution. I have not changed this and it is currently set to 0.
Have tried P3=0 and P3=1 to no avail.
P4 (throttle startup mode) is currently set to 0.
My PAS sensor, (on the pedal hub) has 8 magnets and the 3 wire sensor.
Other settings are 25KM/H, 26" wheel, KM/H speed etc.
Thanks to anyone in advance
