Description

 Two Axes. One EtherCAT Drive

STP-K221A combines two 2-phase microstepping axes, EtherCAT communication, and encoder feedback in one compact drive—providing a simple and flexible way to build multi-axis stepper motor control systems.

 Full-Closed Control

STP-K221A supports full-closed control using either encoder or linear scale feedback, enabling the system to monitor actual position and compensate for position deviation during motion.

MyDrive – Drive Setup & Monitoring Utility

STP-K221A supports simultaneous access through USB and EtherCAT, allowing MyDrive and EtherCAT communication to operate at the same time for flexible drive setup, monitoring, and EtherCAT system testing.

This flexible connection method makes it easy to configure parameters locally via USB while monitoring or testing the drive through the EtherCAT network.
