Y Series EtherCAT Digital Stepper Driver 0-5.6A 24-50VDC for Nema 23, 24, 34 Stepper Motor

The DM556EC is a high-performance open-loop driver with 32-bit DSP technology, operating at 24-50VDC and supporting up to 5.6A current. It features 100Mbps full-duplex EtherCAT communication with CoE (CiA 402) support. The driver offers multiple modes—Cyclic Sync Position, Profile Position, Velocity, and Homing—and includes dual RJ45 ports, optically isolated I/O, and flexible microstepping up to 51200. Smooth current control ensures low noise, low vibration, and minimal motor heating, with built-in protection against overvoltage, undervoltage, and overcurrent.
