Technical Specifications:​ 3-phase 400 VAC class input; continuous current rating consistent with the PB210560 / 21 A frame; DC bus up to 560 VDC nominal; supports resolver, incremental encoder, SFD, EnDat or BiSS feedback depending on option card; PWM current regulation; flash upgradable firmware.

Functional Features:​ Position, speed and torque control modes; four-quadrant regeneration; configurable motor and drive thermal protection; encoder-equivalent output; RS232 / fieldbus commissioning via DRIVE.EXE or WorkBench; patented torque angle control for buried-magnet motors.

Application Scenarios:​ CNC machine tools, packaging machinery, electronic assembly, printing presses, material handling.

Working Principle:​ Rectifies AC mains to DC bus, synthesizes sinusoidal phase currents via IGBT PWM stage, commutates motor based on rotor feedback, closes current/velocity/position loops digitally.

Installation Requirements:​ Panel mount inside grounded control cabinet; vertical orientation with required clearance for convection; segregated shielded motor and feedback cables; 400 VAC 3-phase supply with correctly sized branch fusing; protective earth bonded to cabinet ground.

Usage Notes:​ Verify firmware and motor dataset before energizing; never disconnect motor leads under power; regen resistor mandatory for high inertial load deceleration; observe EMC cable routing and shield termination rules from S400/PD manual.
