Issue Details

I have an AKD EtherCAT drive and I need to know how to wire up the limit switches for my motion system.

Solution

Use the AKD X7 and X8 connectors to connect additional I/O such as limit switches, position capture (registration) inputs, or other I/O as required by your application. Refer to the AKD Installation Manual for information about connecting digital input and output devices to the AKD EtherCAT servo drive.

The image below shows that the associated pins can also be seen in the Axis Configuration windows in LabVIEW SoftMotion Module.

Additional Information

SoftMotion digital inputs and outputs are 0-based, while the digital inputs and outputs on the AKD EtherCAT servo drive are 1-based. This means that Digital Input 1 on the AKD corresponds to DI0 in the SoftMotion software.
