Closed loop mode with Radio RC

You set up your configuration or your script to configure the motor to be in a closed loop mode. You will also need a feedback device to make this work. Either an encoder (digital or incremental) for speed. Then you fine tune your PID as well as your speed and acceleration parameters.

Sounds like possibly a PID tuning issue.

In your closed loop parameters, set the following.

P = 0
I = 2
D = 0

Loop error detection: disabled

Add more I gain as needed until speed reached is close as possible without oscillation.
Add small D gain to add boost in change of speed command.
Add small P gain(decimal value (example 0.3) as needed to reach speed.

The power will be used according to where the speed is and where it needs to be. Therefore it is not always going to go to 100%.

Okay. If you need to reference it, it can be found on page 216. Since it is a configuration value you would use setconfig(_KP, cc, nn) where cc = motor channel and nn = value. KP is the proportional gain.

Unfortunately not. Naturally, the motors when bench set up won't work exactly the same as when connected to the load when fully assembled. Many usually bench test first before putting into their fully assembled application and then further fine tuning as needed. We don't currently have something that would fine tune this as there are other factors that go into tuning.

Other parameters that can have an effect on the PID tuning are the speed and acceleration. Also the type of closed loop mode has various other factors depending on the mode itself.
