Structural Characteristics: The largest form factor in the S700 series to accommodate the high-power components and extensive heat dissipation requirements. Panel-mount configuration with front-panel access to all connectors, LED indicators, and MMC card slot.

Working Principle: The drive uses advanced space vector PWM with DSP-based current regulation to deliver precise sinusoidal currents at up to 48A RMS. The nested control architecture processes feedback from the motor’s encoder or SFD device, computes corrective actions through current, velocity, and position loops, and modulates the IGBT switching to maintain precise motor control under heavy load conditions.
