(5)Throttle Effective Ending Point
Value range: 60%-100%
Functional description: Set throttle effective ending point
Suggestion: Set according to the practical situation, factory default is 90%.
(6)Max Motor Current
Value range: 20%-100%
Functional description: The max motor current is (The Value * Peak Current of the Controller).
Suggestion: Factory default is 100%.
(7)Max Battery Current
Value 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%.
4.2 Step 2
(1)Start-up Delay Time
Value range: 0.0s~2.0s
Functional description: When power is on, set delay time to wait for stabilization of B+, a higher
value means a longer delay time.
Suggestion: Set according to the practical situation, factory default is 0.5s.
(2)Hall Sensor Type
Value range: 60 degree and 120 degree
Functional description: Set according to your motor hall sensor type.
Suggestion: Set according to the practical situation.
(3)Control Mode
Value range: Torque/Balanced/Speed
Functional description: Set controller output mode. Torque mode brings faster response of the
load and good acceleration. Balanced mode brings fast response of the load and wide speed
adjusting range. Speed mode brings smooth operation and wide speed adjusting range.
Suggestion: Set according to the practical situation, factory default is Torque mode.
(4)Under Voltage
Value range: Please see Figure 4.2
Functional description: Controller will not operate when battery voltage is lower than the value
so as to protect battery.
Suggestion: Set according to the practical situation.
(5)Over Voltage
Value range: Please see Figure 4.2
Functional description: 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.
