J1
and
J2
J1 Pin Definition
1- PWR: Controller power supply (output).
2- Current meter. <200mA
3- Main contactor driver. <2A
4- Alarm: To drive reverse beeper. <200mA
5- RTN: Signal return
6- Green LED: Running indication
7- RTN: Signal return
8- Reserved
9- Boost Switch (only available on the controller with 32-bit micro)
10- CAN bus high
11- CAN bus low
12- 12V brake
13- RTN: Signal return, or power supply return
14- Red LED: Fault code.
J2 Pin Definition
1- PWR: Controller power supply (input)
2- RTN: Signal return, or power supply return
3- RTN: Signal return
4- Motor temperature input.
5- Throttle analog input, 0-5V
6- Brake analog input, 0-5V
7- 5V: 5V supply output. <40mA
8- Micro_SW: Throttle switch input
9- Reversing switch input
10- Brake switch input
11- Hall phase C
12- Hall phase B
13- Hall phase A
14- RTN: Signal return
Notes:
1. All RTN and GND pins are internally connected, but isolated from B-.
2. Two PWR pins, J1-1 and J2-1, are internally connected. It’s recommended to use J1-1
to supply peripherals like alarm and contactor. Twist peripheral wires with PWR is the
preferred for EMC.
3. Kelly Ammeter positive connect to 5V power supply of controller, negative to J1-2.
4. Switch to ground is active. Open switch is inactive.
