# AutomationDirect SV2A-2750

Hardware · `SV2A-2750` · verification: source checked

The SV2A-2750 is a SureServo2 AC servo drive rated 7.5 kW with a 230 VAC three-phase input. It controls a servo motor in torque, velocity or position mode and accepts step/direction, CW/CCW, A/B quadrature, internal indexing and analog commands. It communicates over a single RS-485 (RJ45) port using Modbus RTU or Modbus ASCII.

## Safety

- Protection functions: overcurrent, overvoltage, undervoltage, over-temperature, regeneration error, overload, velocity/position error, encoder error, secondary encoder position error, communication error, input phase loss and short circuit.
- A STO connector (ADC part SV2-CN10-STO) is supplied with the drive.
- UL Listed File # E198015; CE declaration available; RoHS status Yes.

## Study notes

- Communication is one RS-485 (RJ45) port running Modbus RTU Slave or Modbus ASCII Slave at up to 115.2 kbaud.
- Control modes are torque, velocity and position; command signals are step and direction, CW/CCW, A/B quad, internal indexing (discrete input and communication port) and torque/velocity via analog input.
- I/O: 10 sinking/sourcing discrete inputs, 6 sinking/sourcing discrete outputs, 2 analog voltage inputs (+/- 10 VDC) and 2 analog voltage outputs (+/- 8 VDC).
- Encoder resolution is 24-bit (16777216 ppr) and an encoder output is provided.
- Output type is SVPWM; tuning modes are easy/auto (4 methods) or manual.
- Configuration is done with software and the keypad; the drive is enclosed and panel mounted.
- EtherNet/IP and Modbus TCP are optional cards, not built into the drive.
- Item shipping weight is 18.1 lb; the drive is intended for use with 7.5 kW systems.
