Basic setup steps for first power on of Fardriver controller.

Timecodes 0:00 first power on of Fardriver after factory reset. 0:10 connect the app. First time might require internet and registration and binding. 0:20 default temp sensor of Fardriver from SiaEcosys is KTY83-122 as used in QS motors. But my motor no sensor. 0:30 default view is SIMPLE NEW BLE, which shows the basic quick start settings. Clicking SIMPLE changes it to EXPERT which shows all the settings 0:44 my motor is 💩 so i have no temperature sensor so I set it for Cacu. Don’t set it to none. 0:52 as soon as its saved, the overtemp alarm goes away, leaving only autolearn dot dot dash notification. 1:02 set pole pairs if you know them. In my case it’s 40 magnets, 20 pole pairs. This ensures all the RPM throughout the app read correctly. 1:30 max line current is the maximum your battery can handle, based on the cells and BMS. 1:38 max phase current is what your motor can take before damage. 1:48 if you use Boost, set it at the maximum amps your DC system can handle for a specific number of seconds. 2:17 I fold my pedals in preparation for autolearn. If your chain will not stay on going backwards, remove it before running autolearn. Make sure the pedals are free to spin if you leave the chain connected. 2:23 I lean the bike over onto its side stand. Use a safe method to get the motor (rear wheel and tire in this case) free to spin along with anything connected by chain. 2:32 Set rated voltage if not 72v. My battery is 16s lithium ion so 59v. 2:54 Low Voltage protection doesn’t change when you change rated voltage so i change it from 63v (default for 72v battery). I set for 50v. 3:27 on the dashboard screen we see autolearn still patiently waiting for use to give full throttle. 3:37 once again get the motor free to spin and then gently give 100% throttle and hold it until the motor runs both directions and comes to a stop. 4:06 that single beep lets you know the autolearn is complete. The ❌ means you are still holding the throttle and you need to release it back to 0. 4:18 it should have saved autolearn data but i save it again for good measure. 4:29 as can be seen by the Ratios on speed table, it has given conservative values and will not let the motor run over 1400rpm, which it feels is maximum. 5:09 I turn off Field Weakening by setting WeakResponse to 7:none. 5:43 speed 1 max rpm is 760. Thats why it stopped speeding up even with full throttle 5:58 speed 3 max rpm just below 1400, held back by the Ratio in speed being 1400RPM @ 0% phase current. 6:17 since Field weakening is off, i can raise all the limits and let back emf limit current as speed increases. 8:39 I set Ratios in speed or allow 100% phase amps up to 1200rpm, limit to 50% at 1300rpm, and cut all current at 1400rpm. With these settings i can set current to maximum and the motor will have maximum torque from 0, and then as soon as rpm increases back emf, it will slowly decrease current. In my tests my bike will find a balance at 40a DC and 45a phase at 72 kph, which is about 1115 motor RPM. 8:51 Autolearn doesn’t calibrate throttle, so on the dashboard while holding a brake we can go from 0 to full throttle and look at the voltage. Mine is 0.81v minimum and 4.10v maximum 9:11 in parameters we set throttle high = to the max voltage (4.10v), but not over 4.3v. 9:24 Low Throttle should be 0.1v higher than minimum signal. 10:45 Throttle ACC step is the acceleration throttle ramp up speed. Lower numbers slower ramp up, 224 if you want torque to instantly follow the throttle. Set 64 if you want slower ramp up. 10:52 Throttle DEC step works in a similar fashion. 224 for more instant response, 32 is slow response. 11:08 my temp sensor is cacu simulation 11:22 I don’t use reverse so i set back speed to 0. If you use reverse, set this speed to the appropriate value for your ebike. 11:26 I will now demonstrate MOTOR DIRECTION, which is what you use to tell the controller which way is forward. 11:45 I set 0, but didn’t save it, motor still goes forward. You have to save certain settings before they take effect. 11:54 now it’s running backwards as shown by the peddles. So if your motor is running backwards after autolearn, change the value in Motor Direction 12:27 time to populate the energy regenerate table. I normally start with the second RPM and give it 20% and then add 10% each level until 100%, then 100% till the end. 14:36 set regen current. Try to stay below your battery AH capacity. Every battery can handle 1c charge. 16:08 FOLLOW is where you set how regen will be activated 16:20 EABS when brake valid gives regen when your brake lever sensor is activated. Thats my preference. But there is also throttle release to make it act like engine braking. 16:23 watch the kickback at the end of regen, because i set first rpm value at 10% 16:54 changing it to 0% on first rpm value stops the kickback but will also make it have no regen at the end of a stop. 17:58 is where you set speed 1-2 (low and medium).
