MC_CommandTable: Run axis commands as motion sequence V2...3

Description

The Motion Control instruction "MC_CommandTable" combines multiple individual axis control commands in one movement sequence.

Requirements

  • The axis technology object has been inserted in V2 and correctly configured.

  • The command table technology object has been inserted and correctly configured.

  • The axis is enabled.

Override response

The MC_CommandTable command can be aborted by the following Motion Control commands:

  • MC_Home command Mode = 3

  • MC_Halt command

  • MC_MoveAbsolute command

  • MC_MoveRelative command

  • MC_MoveVelocity command

  • MC_MoveJog command

  • MC_CommandTable command

The new MC_CommandTable command aborts the following active Motion Control commands:

  • MC_Home command Mode = 3

  • MC_Halt command

  • MC_MoveAbsolute command

  • MC_MoveRelative command

  • MC_MoveVelocity command

  • MC_MoveJog command

  • MC_CommandTable command

The active Motion Control command is cancelled by the start of the first "Positioning Relative", "Positioning Absolute", "Velocity set point" or "Halt" command.
