ParameterSets

[Key name of the parameter set]

CfgSpeedControl

vCtrlPropGain

vCtrlIntGain

vCtrlDiffGain

The parameter object CfgSpeedControl is not required for:

Virtual axes (MP_axisMode=Virtual)

Axes that are for display only (MP_axisMode=Display)

Analog axes (MP_axisHw=Analog)

The actual speed values are measured directly at the motors with

HEIDENHAIN rotary encoders. The position controller provides the nominal

speed value. The speed controller is driven by the difference between nominal

and actual speed values. It provides the nominal current value as output.

Use Module 9164 to read the actual speed value of the motors.
