{"id":"automationdirect-sv2a-4550","model_id":"SV2A-4550","name":"AutomationDirect SV2A-4550","summary":"The SV2A-4550 is a SureServo2 AC servo drive rated 5.5 kW on a 460 VAC three-phase input, with a 16.8 A rating and SVPWM output. It controls a servo motor in torque, velocity or position mode using step/direction, CW/CCW, A/B quadrature, internal indexing, or analog torque and velocity commands. Setup is through software and a keypad, and it communicates over a single RS-485 port using Modbus RTU or Modbus ASCII.","study_notes":["One RS-485 (RJ45) communication port, Modbus RTU Slave and Modbus ASCII Slave, up to 115.2k baud.","Command signals: step and direction, CW/CCW, A/B Quad, internal indexing (via discrete input and communication port), torque and velocity via analog input.","I/O: 10 sinking/sourcing discrete inputs, 6 sinking/sourcing discrete outputs, 2 analog voltage inputs (+/- 10 VDC), 2 analog voltage outputs (+/- 8 VDC).","Encoder resolution 24-bit (16777216 ppr); encoder output supported.","Internal protection functions: overcurrent, overvoltage, undervoltage, over-temperature, regeneration error, overload, velocity/position error, encoder error, secondary encoder position error, communication error, short circuit.","For use with 4.5 kW and 5.5 kW systems.","Optional EtherNet/IP and Modbus TCP cards available; these protocols are not on the standard unit.","Enclosed housing, panel mounting, 0 to 55 deg C temperature rating.","Item shipping weight 13.45 lb; country of origin Taiwan."],"safety_notes":["UL Listed, file # E198015; UL Recognized and UL Hazardous files listed as None.","CE declaration and EU REACH document provided; RoHS status Yes (see CE doc).","STO connector (ADC part SV2-CN10-STO) supplied with the drive."],"sources":[{"url":"https://www.automationdirect.com/adc/shopping/catalog/motion_control/sureservo2_(sv2a_series)_servo_systems/460v_servo_motors,_drives,_motor_cables/sv2a-4550","title":"Servo Drive: Modbus RTU and ASCII, 5.5 kW, 460 VAC, 3-phase (PN# SV2A-4550) | AutomationDirect","accessed":"2026-10-26"},{"url":"https://cdn.automationdirect.com/static/specs/cutsheet/SV2A-4550_cutsheet.pdf","title":"SV2A 4550 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":5.5,"rated_current_a":16.8,"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-4550","license":"https://creativecommons.org/licenses/by/4.0/"}
