Parker FL20-SA113T3 Servo Drive Unit

Module Feature

FL20-SA113T3 is Parker FL20 series high dynamic servo drive, rated power 11kW, three-phase 380VAC power supply. It supports multiple control modes: pulse position, analog speed, analog torque and internal preset speed/torque. Accepts incremental encoder or resolver feedback, bandwidth up to 1.2kHz for fast response. Built-in electronic overcurrent, overvoltage, overheat and encoder loss protection. It supports optional PROFIBUS or CANopen communication card, DIN rail cabinet mounting. Widely stocked as maintenance spare for film stretching machine, printing press, packaging and metallurgical motion control cabinet.

Working principle

Three-phase AC input is rectified to DC bus, then IGBT power stage outputs PWM adjustable AC to servo motor. Control core executes vector algorithm to separate flux and torque current, closes position/speed loop according to encoder feedback. Drive continuously samples bus voltage, output current and temperature. Once fault condition is triggered, it latches fault code and stops output safely.

Onboard components

Rectifier bridge, IGBT power module, DC bus capacitor bank, current sampling Hall sensor, encoder feedback interface, control CPU board, status LED bank, operation panel connector and metal chassis.

LED indicators

Front panel LEDs indicate power, RUN, fault alarm and communication status; digital keypad panel displays running data and fault codes.

Hardware self‑diagnosis

Built-in supervision detects overcurrent, bus over/under voltage, heatsink overtemperature, encoder signal loss, communication timeout and internal hardware error. Configuration and fault diagnosis are completed by Parker dedicated FL20 commissioning software.

Programming softwareParker FL20 configuration tool, used for motor auto-tune, loop gain setup, command source selection, bus parameter and fault history reading.
