MC_ReadActualPosition – Read actual position
Block SymbolLicensing group: MOTION CONTROL
Function Description
The block MC_ReadActualPosition displays actual value of position of a connected axis on the output Position. The output is valid only while the block is enabled by the logical input signal Enable.
The block displays logical position value which is entered into all of the motion blocks as position input. In case that no absolute position encoder is used or the internal position is set in other way (e.g. via MC_Home block), the CommandedPosition output of the corresponding RM_Axis may display different value.
