# AutomationDirect SV2A-4150

Hardware · `SV2A-4150` · verification: source checked

The SV2A-4150 is a SureServo2 AC servo drive rated 1.5 kW with a 460 VAC three-phase input. It controls torque, velocity and position, and takes step/direction, CW/CCW, A/B quadrature, analog and internal indexing commands. It communicates over one RS-485 (RJ45) port using Modbus RTU or Modbus ASCII.
