(1)Low Volt: The min voltage of reporting this fault - Range 180~450
Controller will not operate when battery voltage is near the value so as to protect battery.
Suggestion: Set according to the practical situation. By default, it is set at 180V.
(2)Over Volt: The max voltage of reporting this fault - Range 180~450
Controller will not operate when battery voltage is higher than the value so as to protect battery
and controller.
Suggestion: Set according to the practical situation.

(3)Current Percent: Phase Current Percent. Range: 20~100
Functional description: The max motor current is (The Value * Peak Current of the Controller).
Suggestion: Factory default is 100%.
(4)Battery Limit: Battery Limit Current, Limit the max value of Battery Current. Range: 20~100
Functional description: Set max battery current so as to protect battery. A lower value means a
lower battery output current and better protective effect. But excessively low value will affect
acceleration.
Suggestion: Factory default is 100%.
(5)Identification Angle: Please download the instruction to how to use Identification angle
function from the website.

If you can read 85 in Identification Angle item, that is to say, the system is stable and normal.
Please fill in 170 for Identification Angle item in user program. Then
please click Write button in user program. Please wait a few seconds before restart the power
supply. You will see some info on Monitor screen after power supply is
reset. If you see Reset error on the Monitor screen, that is to say, the auto_Identification is
finished. You can see 85 in the Identification Angle item again. And the controller will
blink error code. This is normal. Please reset the power supply again. Then everything will be
fine. The motor is ready to be drived by the KHS controller.
Range: 85 or 170, nothing else.
(6)TPS Low Err: Hall active pedal, if lower than the value, report the fault of TPS Type. Range:
0~20
