I'm curious on what exactly 'holding limit' does.

Is this a limit on the maximum throttle percentage the unit can use for long term loads? Or is this a limit on how long the unit holds the throttle in a certain position after a long term load?

If holding limit is say..70%, does that mean the governor, during a long term load, will never move throttle past 70%? etc. (for example, on nitro a power loop might need full throttle through the entire duration).

A better understanding of this value would be helpful in setting in properly.

Also a question for Tomáš - does the spirit governor algorithm have a predetermined minimum throttle value that it can use to avoid overspeeding? For example, the multigov pro has a setting for the minimum throttle value the unit can use while governing to avoid overspeeding during a fast load change (default is 30% above idle, so about 40% throttle)

Hello,

holding limit is limiting integrative regulation term.
This term is allowing to counteract long term headspeed deviations from requested headspeed.

Holding Performance is defining how fast the correction will be made. But if rpm difference is big the integrative term will increase to a high values.
When load becomes smaller than this term is still too high. Higher than it should be.

With the limit you can set how high the integral term can go. So then it can be much faster to return throttle to original value. So it can help with overspeeding a lot.

So it is not limiting throttle output value.

Yes, it has minimum value of the throttle. This is approx. 2/3 of the setpoint for requested rpm.

Otherwise motor could stop without this limit.
