Ch ap te r 7 Motion Co n tro l Prog ramming7 - 57_7.3 Motion Control InstructionsTo perform motion control function, you will need to use motion control instructions which are mostly function block POUsprovided by AH Motion Controller CPU. In AH Motion Controller system, the naming of function blocks has two types. Oneis DFB instruction (Delta Function Block), which is developed by Delta to enhance the usability. Another one is MC, whichcomplies with the motion control function block standard defined by PLCopen.For details of motion control instructions, refer to AH Motion Controller – Motion Control Instructions Manual7.3.1 Function Blocks for AH Motion Controller CPU DFB ( Delta Function Block) instructionsDFB instrictions are Delta-defined instructions categorized as single-axis, multi-axis, auxiliary, network, and fieldapplication instructions. These instructions are provided for achieving various control purposes. MC instructionsPLCopen standardizes the motion control function block interface in IEC 61131-3. MC instructions provided by Deltacomply with the PLCopen standard and make the user program less hardware-dependant and highly-reusable amongdifferent controllers. This feature reduces the time and effort on developing, tuning and maintaining the control system.
