{"id":"automationdirect-sv2a-4040","model_id":"SV2A-4040","name":"AutomationDirect SV2A-4040","summary":"The SV2A-4040 is a SureServo2 series AC servo drive rated 400 W, fed from a 460 VAC three-phase supply. It controls a servo motor in torque, velocity or position mode, accepting step/direction, CW/CCW, A/B quadrature, internal indexing and analog command signals. It communicates over one RS-485 (RJ45) port using Modbus RTU or Modbus ASCII, and is configured by software or keypad.","study_notes":["Rated 1.5 A input current with SVPWM output.","Encoder resolution is 24-bit (16777216 ppr); encoder output is provided.","RS-485 (RJ45) port runs at up to 115.2k baud.","I/O: 10 discrete inputs, 6 discrete outputs (sinking/sourcing), 2 analog input channels (+/- 10 VDC) and 2 analog output channels (+/- 8 VDC).","Tuning modes: easy/auto (4 methods) and manual.","Command signals: step and direction, CW/CCW, A/B quad, internal indexing via discrete input and communication port, torque and velocity via analog input.","Configuration via software and keypad.","EtherNet/IP and Modbus TCP are available only as optional cards, not built in."],"safety_notes":["Protection functions stated: overcurrent, overvoltage, undervoltage, over-temperature, regeneration error, overload, velocity/position error, encoder error, secondary encoder position error, communication error and short circuit.","Enclosure is IP20, so it must be installed in a protected panel environment.","UL Listed File # E198015; CE marked; RoHS status Yes."],"sources":[{"url":"https://www.automationdirect.com/adc/shopping/catalog/motion_control/sureservo2_(sv2a_series)_servo_systems/460v_servo_motors,_drives,_motor_cables/sv2a-4040","title":"Servo Drive: Modbus RTU and ASCII, 400W, 460 VAC, 3-phase (PN# SV2A-4040) | AutomationDirect","accessed":"2026-10-26"},{"url":"https://cdn.automationdirect.com/static/specs/cutsheet/SV2A-4040_cutsheet.pdf","title":"SV2A 4040 cutsheet","accessed":"2026-10-26"}],"verification":{"status":"source_checked","checked_at":"2026-10-26","values":11,"method":"llm_source_check"},"updated_at":"2026-10-26","type":"hardware","spec":{"category":"servo_drive","manufacturer":"automationdirect","controllers":[],"supply_voltage":"460 VAC, 3-phase","rated_power_kw":0.4,"rated_current_a":1.5,"feedback":"24-bit (16777216 ppr)","output_type":"SVPWM output","ip_rating":"IP20","operating_temp_min_c":0,"operating_temp_max_c":55,"joints":[],"protocols":["modbus-rtu","modbus-ascii"],"standards":[],"error_codes":[]},"url":"https://machineschema.com/hardware/automationdirect-sv2a-4040","license":"https://creativecommons.org/licenses/by/4.0/"}
