- Faulty ESC
|
| Case2 |
- Motor open, motor short to battery
|
| Case3 |
|
| Case4 |
- Motor ground circuit open
|
| Case5 |
|
| Threshold Value |
Case1 |
- A failure is detected if the motor voltage is below 7 times during motor relay is on
- A failure is detected if the voltage difference between power side and load side of motor relay is higher than 0.85 to 1.15V for more than 100ms during motor relay is on
|
| Case2 |
- A failure is detected if the motor voltage is higher than 3.5 to 4.5V for more than 500ms during motor relay is off (This monitoring works after motor relay is switched off over 1.8s)
|
| Case3 |
- If any following condition is monitored, controller drives motor maximum 3 times for test. A failure is detected if any following condition is satisfied continuously during test
- Motor voltage is below 0.4 to 0.6V within 20ms, after motor is off
- The decreasing rate of motor voltage for 1s is out of normal range after motor is off
|
| Case4 |
- A failure is detected if ground voltage is higher than 5V for more than 500ms during motor relay is on
|
| Case5 |
- A failure is detected if motor power voltage is lower than 3.5 to 4.5V for more than 1s
|
