(1)Low Volt: The min voltage of reporting this fault - Range 18~173, depending on model.
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 18V.
(2)Over Volt: The max voltage of reporting this fault - Range 18~173, depending on model.
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.
Here is the max voltage for each model.
72V controller: 86V
96V controller: 115V
120V controller: 144V
144V controller: 173V

(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,
