The AKT2G family is recommended for new applications requiring remote I/O in a PCMM or PDMM KAS application. This article, and the attachment, compares the AKT2G Remote I/O family with the AKT Remote I/O family.
Notes:
- The AKT2G family incorporates new capabilities including Stepper Drives, Incremental Encoder input, and a configurable Analog Input slice.
- Before utilizing remote I/O, a user in the application, should consider the built in I/O capability of the servo drives as this could eliminate the need for the AKT2G.
- AKT2G I/O is fully integrated into a KAS application via the EtherCAT high speed synchronous network
