GetSpeedOverride and SetSpeedOverride Function
(Original Document)
About us
Description
The GetSpeedOverride function sends the relevant speed modulation coefficient to an axis.
The SetSpeedOverride function sets the relevant speed modulation coefficient for an axis.
The value is explicitly specified as a percentage.
The coefficient is between 0 and 100.
A modulation coefficient of 0% would render the axis immobile.
A modulation coefficient of 100% would cause the axis to move at the commanded speed.
NOTE: The coefficient affects the acceleration and deceleration values.
NOTE: The axis follows the same trajectory whatever the speed modulation coefficient value.
