Speed Engineering Setup

The Speed Controller Engineering Setup page contains advanced settings for governor operation. An access level of Engineering is needed to use this page. A description of each setting is listed below.

Governor Advanced Setup

Starting Throttle: This is the throttle position that is held when the engine is cranking. If an engine is hard to start, this could be increased. If an engine starts but overshoots the idle rpm, this could be decreased. Note: When the engine is not turning, the throttle is kept closed. The Governor only opens the throttle when it detects flywheel movement.

Crank terminate RPM: This is the value which the Governor uses to determine if the engine is done cranking. It would not likely need to be changed unless an engine cranks very quickly.

RPM Ramp Rate: This value determines how fast the RPM will change when changing between modes (Auto/Idle/Manual). It does not affect how fast the throttle changes when a mode is not changing.

Gov throttle gain adjustment: This value, which can range from 1-100% with a default of 50%, scales the control gains for current to the throttle. A higher value will make the throttle move more quickly but can make the throttle more erratic.

Gov rpm gain adjustment: This value, which can range from 1-100% with a default of 50%, scales the control gains for the throttle. A higher value will result in faster response but possibly more instability. A lower value will result in slower response but more stability.

Maximum throttle position: This gives a maximum position of the throttle. This might be used with external throttles to stop the linkage from being overdriven.
