Dear all,

I am using a single axis AKD drive (AKD-P00306-NBAN-0000, 3A, 120/240Vac, Analog) and a AKM brushless motor to obtain a linear movement back and forth.

I would like to obtain a continuous cyclic specific motion profile (one cycle as an example is shown in the picture, velocity over time).


Is there a way to do S Curve Profiling over Ethernet IP with the AKD ( i.e. from an Allen Bradley PLC ) based on there is a S-Curve option in the Motion Task tables. Is there a way to do this over EIP ( send the data table values, etc. )?

How can we take advantage of that feature using EIP as a fieldbus?


The short answer is this cannot be done using the motion tasking drive over Ethernet IP or Modbus TCP for that matter.

The AKD_Move add-on-instruction ( AOI ) has no built-in S-Curve feature or capability.

Use the Excel file titled “AKD S-CURVE GENERATOR TWO.xls” (see attachment) to generate a csv file with the profile data.

Select a Motion Task from the navigation menu.  (Note that double-clicking on the task from the Motion Task Table will not take you to the same screen.)
