Governor

1 Vorbereitung

Der Drehzahlregler der Spirit-Einheit (sog. External Governor) kann mit allen Single-Line Digital-Receiver-Verbindungen verwendet werden. Dies bedeutet, dass es für PWM und PPM nicht verwendet werden kann. Damit es funktioniert, benötigen Sie einen RPM-Sensor, der das Gerät mit aktuellen RPM Daten versorgen kann.

Für die Verwendung dieses Reglers ist es notwendig, die Drosselklappe (ESC oder Drosselservo) am AUX (AUX1) Port anzuschließen.

2 Liste der getesteten Sensoren

Damit der Regler gut funktioniert, ist es sehr wichtig, einen geeigneten RPM-Sensor zu wählen. Es ist bekannt, dass die folgenden gut funktionieren.

Elektromotoren

• HobbyWing Platinum ESC v3/v4 RPM Ausgang
• YGE ESC RPM Ausgang
• CC Phoenix Edge RPM Ausgang
• Scorpion Commander V RPM Ausgang
• HobbyWing RPM Sensor
• Orange RPM Sensor

Nitro und Gasser Motoren

• Align HE50H22 RPM Sensor
• Spartan SRC-RPM RPM Sensor

3 Autorotation Rettungsfunktion (Bailout)

Für jene Piloten, die Autorotationen durchführen, kann die Rettungsfunktion (Bailout) sinnvoll sein. Diese Funktion ermöglicht es, den Motor schnell auf die Flugdrehzahl hochzudrehen, wenn nötig. Sie können die Autorotation Bailout rate in den Advanced/Expert settings ändern.

Damit es funktioniert, musst du nur deinen Sender einstellen.

• Bei der Autorotation nicht Throttle Hold betätigen.
• Verwenden Sie stattdessen einen zugeordneten Schalter, der die Gaskurve zwischen 12 - 50% einstellt.

Wenn die Gaskurve unter 12% fällt, wird normal hochgedreht.

4 Throttle Hold für Autorotation (optional)

Falls Sie nur Throttle Hold für die Autorotation verwenden möchten, führen Sie bitte folgende Schritte aus:

1. Setzen Sie die Gaskurve für Hold auf 12%. (Dies wird den Motor hochdrehen)
2. Decrease General/Governor/Throttle Range - Min. until the motor will stop completely.
3. Increase the Spoolup Rampup until you will get immediate spoolup when Hold is disarmed.

5 Troubleshooting

• A delay between disarming Throttle Hold and motor rotation - motor will start to spin after a short time.

Make sure that your Throttle Range was configured correctly. Did you calibrated the throttle range with the Spirit connected?

We recommend to put the ESC into the Factory settings. In the most cases the default range is matching with preconfigured range in the unit (1100μs - 1900μs).

In case that the range is configured correctly, but there is still a noticeable delay, please increase the Spoolup Rampup parameter until the motor will start to spin instantly after disarming the Hold switch.

• Motor will kick after disarming the Hold switch causing unwanted rotation of the model.

Decrease the Spoolup Rampup parameter until the kick will disappear. If you will notice a delay before spooling, the value is too low now and other solution must be used. In this case the problem cannot be solved by any settings of the Spirit unit.

Check if the ESC supports a Spoolup Power parameter. If it is supported, then try to decrease the power and observe if it will help you. In some cases a different Timing or PWM frequency can help, but always make sure that the settings are valid for your motor.

• After demanding maneuvers the head speed is maintained at higher RPM for prolonged period.

Verify that the Throttle Range of your ESC or Throttle servo is configured properly. Usually the problem is caused by exceeded limit for the full throttle defined by Throttle Range - Max. value. For example, if the top limit in the ESC is programmed to 1800μs but the unit has configured 1900μs, then the unit will be 100μs over the real limit. Thus during a high load it could take a few seconds until the value will drop under 1800μs in this case.

Correct solution is to reconfigure the Throttle Range either in the ESC or in the unit.

• There is often "RPM Sensor data are too noisy" event in the flight log.

Make sure that the connection of the RPM Sensor output is good. If the RPM Sensor is separated from the ESC, please connect its power supply (especially the grounding wire) as close as possible to the RPM signal wire in the unit. Usage of a ferrite rings for the power supply could reduce a noise as well. Verify operating voltage requirements for the sensor. Some sensors require 3.5V or more so they can't be powered from the Spektrum port of the unit. In some cases it is caused by too high Governor Response value, because motor will start to jitter.

• Governor is not switching between different throttle curves.

Your Throttle Range in the ESC is calibrated incorrectly - range that unit is programmed for is not matching range of the ESC. Correct calibration of the range will solve the problem.

• RPM signal was lost.

If Governor will loose the signal, it will detect the event within 2 seconds. Governor will still work, but with worsened performance - similarly as with a V-curve. This event can happen, if the signal cable connection will fail. For this reason we highly recommend to use a hot glue or other way for securing the connections.
