Kunteng KT LCD-8 display C5 setting

[Comrade]

I can't figure out what 00, 01 and 02 settings actually do. I tried them on the bike, but don't really notice a difference between any of them.

Does 00 mean that power will be ramped up to maximum in 3 step? Doesn't make any sense why it would be designed with steps since the controller could have done the ramp up smoothly. The processor is certainly advanced enough for that.

As opposed to 10 which would apply full power immediately? Are 00, 01 and 02 designed to prevent shock and jerkiness?

From the wording and the typical way such things may work, I would guess that it is simply three different settings for the slow start value, with level one the least restrictive and level three the most restrictive, given that the progression of 10 to 0 in setting value decreases current for each step.

There are two likely ways the levels might work: Either the ramps are longer for each setting, but the current goes up to the same amount for each, or the ramps are the same for each setting but the current it finalizes at is less for each lower C5 value.

In general, slow start is used as you say, either to prevent shock loading on drivetrain parts, or to prevent jerkiness to the rider with sudden application of power.

With low power systems it's generally unnecessary with throttle usage because ramping can be controlled by the rider directly, but with PAS systems that are only on/off control (of whatever assist level is chosen), it can smooth out the ride.
