# AutomationDirect SV2A-4075

Hardware · `SV2A-4075` · verification: source checked

The SV2A-4075 is a SureServo2 AC servo drive rated 750 W with a 3-phase 460 VAC input. It controls a servo motor in torque, velocity or position mode and connects to a host over a single RS-485 (RJ45) port using Modbus RTU or Modbus ASCII. Optional EtherNet/IP and Modbus TCP cards can be added for other networks.
