Design and Performance
High-Performance Solution for the Most Demanding Applications
As part of the acclaimed Unidrive SP series renowned for its advanced features, exceptional reliability, and versatility, the SP6401 delivers precise motor control, energy efficiency, and robust performance for the most demanding industrial applications.
Obsolete Platform Still Widely Supported for Maintenance
Nidec has officially declared the entire Unidrive SP series obsolete, but the SP6401 remains actively sourced new, refurbished, and via repair-exchange programs for maintenance and like-for-like replacement, avoiding the costly retrofit of large motor control installations.
Wide Voltage Range for Global Deployment Flexibility
Operating across a 380 to 480 VAC input voltage range, the SP6401 ensures compatibility with various power supply systems, making it a versatile solution for industrial settings across different regional voltage standards.
Auxiliary 24VDC Supply for Continuous Control Readiness
Requiring a separate 24VDC power supply for control circuits, this drive can keep its control logic active even when the main AC supply is removed, supporting safety backup readiness for critical large-motor equipment.
Consistent Platform Across the Unidrive SP Range
Sharing the same flexible control interface and software parameters as smaller Unidrive SP sizes (from the compact SP0202 up through SP5402), the SP6401 lets engineers standardize commissioning knowledge across projects using multiple drive frame sizes.
