ESC Throttle govenor problem--------------------------------

[Mike_Snoo]

Hi all,

I am using a BLHeli S ESC connected on Aux 1 to the Spirit Unit. I have on my radio (TX16s - Edge TX 2.6) on a 3 way switch my throttle settings. 1. Position : Idle up Low
2. Position: Idle up high
3. Position : Poti sets the throttle level.

I see in the diagnostic tab that the throttle setting in the Spirit unit is received correctly. Depending on how I programm my radio the right throttle value arrives.

However, the ESC and Motor spinns up to full speed if the throttle value on my curves is higher than 1500us. No matter if 1501 or 1900us its always full throttle. If it's below 1500 I get something like half throttle and even then it doesnt matter if 1100 ir 1499us. Always the same head speed.

On the govenor page I see that the desired RPM goes to the correct values, but I don't see any reading from the ESC. I guess with PWM is a one way signal.

The rotor is slowing spooling up, so the settings in general must be right.
If I switch to the 3rd position with the poti, the Heli goes almost immediatly to the desired head speed without slow spooling up.

What could cause that?

Hello,

Spirit Governor require to have RPM sensor connected at the PIT pin of the Spirit unit.
If it is not connected, it will spin for full RPM, because it can`t sense any RPM signal.

Please make sure you have RPM cable connected. From the second half, Spirit Governor is used. Under the first half signal is being retransmitted from radio. So behavior seems to be good, except no RPM signal.

Alright, thanks for letting me know. My ESC doesn't have a RPM signal wire. I just ordered the RPM Sensor. I hope you will integrate bi directional Dshot or any other ESC protocoll with RPM telemetry. ( Asked for that in the Whislist group ). Until then I will just connect the ESC directly to the receiver.

Unfortunately there is no ESC telemetry protocol that has fast data rate enough for Governor to work well. But dshot can be implemented with future update.
Measurement must be performed directly by unit so there is zero delay.

[Mike_Snoo]

Dshot should be fast enough. It works with other solutions.

I ordered the Spirit Hall Sensor and found another one in the box. I put one magnet on the main shaft and for each RPM I receive when the magnet passes a low signal. I set the devider to 1, but the govenor is still not working. I see that i get a requested rpm and I see that the sensor is delivering a signal change, but it doesn't calculate a RPM. Current rpm is always 0.

Hello,

please set Throttle to 50% or more. This is required, otherwise Governor will not work. At the same time you should see Current RPM.
If TC is under 50% then unit is sending signal from your radio to the ESC, while Governor is disengaged.
All other things seems to be OK from your description.

[Mike_Snoo]

I did that. Throttle is on hold over 50%. I see that the rpm requested changes depending on throttle low or high settings of my radio.

It seems like the unit is not calculating. If I'm in the tester window and turn the rotor by hand, it should show like 30-100rpm or so, but it doesn't. The sensor is sending a signal, I see that it switches from active to inactive.

[ZeXx86]

Can you see that throttle is over 50% also in the Diagnostic tab?
Yes, you should see also low RPM.

What Gear Ratio and Sensing Divider is configured? What is your model?

[Mike_Snoo]

See the pictures, that's both during spool up. I have a Alzrc X 360. I added a 2nd magnet. I will provide a video in a bit with the reading when i spin the rotor by hand.
