Motion Control Instructions

To perform motion control function, you will need to use motion control instructions which are mostly function block POUs
provided by AH Motion Controller CPU. In AH Motion Controller system, the naming of function blocks has two types. One
is DFB instruction (Delta Function Block), which is developed by Delta to enhance the usability. Another one is MC, which
complies with the motion control function block standard defined by PLCopen.

Function Blocks for AH Motion Controller CPU


DFB ( Delta Function Block) instructions
DFB instrictions are Delta-defined instructions categorized as single-axis, multi-axis, auxiliary, network, and field
application instructions. These instructions are provided for achieving various control purposes.

MC instructions
PLCopen standardizes the motion control function block interface in IEC 61131-3. MC instructions provided by Delta
comply with the PLCopen standard and make the user program less hardware-dependant and highly-reusable among
different controllers. This feature reduces the time and effort on developing, tuning and maintaining the control system.
