3.Kelly Controller Software Interface

Here are the clear and easy adjustment software interface for reference:

DJ7091Y-2.3-11 Pin Definition

(14) REV_SW: Reverse switch input. Orange

(6) RTN: Signal return or power supply return. Black

(12) FWD: Forward switch or can be enabled as High speed switch function. White

(11) 12V:12V Source Red

(25) 12V brake switch. Yellowish

(22) ECO: Low speed switch function. Blue

(33)CAN-H:Greenish(Optional function)

(7) PWR: Controller power supply (input). Pink

(34)CAN-L:Brownish(Optional function)

DJ7091Y-2.3-21 Pin Definition

(15) Micro_SW: Throttle switch input. Gray

(3) Throttle: Throttle analog input, 0-5V. Dark Green

(20) RTN: Signal return. Black

(8) Meter: Copy signal of hall sensors. Dark Gray

(4) 5V: 5V supply output, <40mA. Purple

(2) Brake_AN：Brake variable regen or Boost function. Brown

DJ7061Y-2.3-21 Pin Definition

(21) RTN:Signal return. Black

(1) Temp: Motor temperature sensor input. Raddle.

(5) 5V: 5V supply output,<40mA.Purple

(18) Hall A: Hall phase A. Yellow

(17) Hall B: Hall phase B. Dark Green

(16) Hall C: Hall phase C. Dark Blue

Notes:

1. All RTN pins are internally connected.

2. Meter function is to copy either of hall sensors.

3. Switch to 12V is active. Open switch is inactive.

4. F-N-R control and three speed function can not be used at the same time.They both

used the same pin as pin12=FWD

Pls. contact with sales first if you don't know how to connect the controller with motor and other parts.

5.Questions before order

1). If you want to buy the controller separately, please advise us the parameters of your matching motor?

Such as Motor Voltage, Wattage, Speed...

2). If you need any other special functions for this controller, please feel free to contact to us. Thank you!
