Axis group override with MC_GroupSetOverride

MC_GroupSetOverride is used to override the speed of an axis group movement command. The override rate is applied to the relevant axes and can be changed while the Enable input is On. If the VelFactor is 0.0, the axes will stop moving and enter StandStill state.

  • Only positive values may be set to VelFactor and a negative value will result in a function block error.

  • Override factor value of 1.0 will mean increase the velocity/acceleration/jerk by 100%.

  • LS_Connect, MC_GroupEnable and MC_GroupPower (or equivalent) must be executed before this function block.

  • The examples in this topic can be found in the XMC_AxisGroup_FBs.zip downloadable from Example Applications.

Element Name Element Type Description
Enable Input Level detected request to execute the function block.
AxesGroup Input/Output Set the group to execute the function block on. Group number 1-16. This must be an UINT variable.
VelFactor Input Specify the override rate of the velocity.
AccFactor Input Specify the override rate of the acceleration.
JerkFactor Input Specify the override rate of the rate of change for acceleration.
Enabled Output Indicates the function block is enabled.
Busy Output Indicates the function block is in operation.
Error Output Indicates whether an error occurs or not.
ErrorID Output Indicates the error number if an error is present.

Distance Array:

  • [0] – Axis 1 distance

  • [1] – Axis 2 distance

  • [2] – Axis 3 distance

  • [3] - Axis 4 distance
