Hi and
to the forum.
The only information I have seen for those controller is in the
High Power BLDC Controller User Guide but it doesn't mention anything regarding the parameters highlighted in your screenshot.
I'm guessing that the
Phase current runtime (S) is the number of seconds that the controller is able to supply the
Phase max current (A) for.
Unfortunately, I don't know what the other four settings relate to, but I suspect it may have something to do with fine tuning the torque output of the motor.
Check out
this whitepaper on BLDC motor control to see if any of it makes any sense to you, as it's far too advanced for me to understand.
I would leave the default values alone unless you can notice any improvements by trying slight adjustments on a "trial and error" basis.
UPDATE:Bus max current (A) The max bus (battery) current, will run at 50% when continuous runtime is more than Phase current runtime (S).
Phase current runtime (S) The runtime of max current, the max is 180 seconds.
Speed –I (%) Controller speed control loop I parameter controls, range is 1 to 99, the greater the value, the faster the reaction, the smaller on the contrary, (should reduce this value if speed fluctuations large, on the contrary increase it). When used in cruise speed control, first adjust the parameter of P then the I.

When used in pedal speed control, first adjust the parameter of P then the I.
