Axis variables

Axis variables are used to control position, speed, acceleration, and error for a given motion control axis.
  • In a function block diagram
    Graphically connect the axis output parameter of a motion control function block to the AxisIn input parameter of another motion control function block for convenience. For example, connect the MC_POWER axis output parameter to MC_HOME AxisIn input parameter.
  • In a ladder diagram
    A variable cannot be assigned to the axis output parameter of a motion control function block because it is read-only.

Monitor an AXIS_REF variable

Monitor an AXIS_REF or a FBAXIS_REF variable in the software when connected to the controller, when the motion engine is active, or in the user application as part of user logic. You can also monitor the AXIS_REF or FBAXIS_REF variable remotely through various communication channels.
