KEEP CURRENT(%)
The percentage of current that is maintained at a certain rate of pedaling (cadence). It is the percentage of
the current limit set per each level of PAS.

SLOW-START MODE
Controls how quickly the power ramps up.
STARTUP DEGREE (SIGNAL NO)
The number of sensor steps before the start up commences. The maximum accepted is 20. 24 is a full pedal
revolution. Too few makes start-up occur with too slight a pedal movement. Lower number is less pedal
movement to start the motor. Does not work properly with 1 or 0.
WORK MODE ( ANGULAR SPEED OF PEDAL/WHEEL *10)
Adjusts the amount of power that can be applied to each pedal rotation. The higher the number the greater
the power applied to each rotation. This might aect at what rpm peak power sits in PAS operation, changing
it doesn’t seem to be noticeable so we advise to leave it alone.
TIME OF STOP (X10MS)
This aects how quickly the drive stops after you stop pedaling.. If you set it to 0 the PAS system ceases to
work. 25 is probably too high. This setting disables the PAS if it is set less than 5. I strongly recommend
setting this to 5, especially if you want to use the PAS system without using e-brakes.
CURRENTDECAY(1-8)
Determines how high up the pedal cadence rpm range it starts to reduce power, 8 being the highest. There is
no detail on actual rpm speeds for the Current Decay setting. The lower this setting is the sooner the drive
unit will start cutting back on the power as you pedal faster.
E.g.: For 50% current limit set for level 5, if the keep current is set to 70%, the keep the current limit will drop to 35% while
pedaling faster(at a higher cadence), but once the cadence drops the current will increase back to the current limit set for the
certain level. The pedaling cadence value can be modied by changing the value of current decay.

Some people report that setting this lower (as low as 5) may aect the startup delay on the throttle If you set this less than 10 on the
v2 of the BBS02 controllers then your PAS will not work properly at all. On the older BBS02v1 controllers and the BBSHD controllers
you can set this as low as 5 before you start having issues with the PAS
