Design and Performance
Sensorless Flow Vector Control for High Performance Without Encoder
Operating in Open Loop Flow Vector Control (RFC) mode, the SP1405 controls magnetizing and active current separately using drive-calculated motor parameters, estimating rotor speed and position without requiring a speed sensor, delivering very high performance for the majority of standard motor applications.
Obsolete Platform Still Widely Supported for Maintenance
Nidec has officially declared the entire Unidrive SP series obsolete, but the SP1405 remains actively sourced new, refurbished, and via repair-exchange programs for maintenance and like-for-like replacement, avoiding the complications of a full drive system retrofit.
Servo-Capable Platform with Click-In Option Modules
As part of the Unidrive SP servo-capable range, the SP1405 delivers dynamic performance to operate a wide array of servo motor types, with click-in SM option modules allowing the addition of programming platforms, distributed or centralized control architecture, I/O, communications, and feedback options.
Higher Braking Resistor Group for Increased Power Applications
Sharing a dedicated braking resistor group with the SP1406 (minimum 58 Ω, 10.6 kW instantaneous power), this drive supports properly matched dynamic braking for the higher end of the SP140x sub-range’s power capability.
Consistent Platform Across the Unidrive SP Range
Sharing the same flexible control interface and software parameters as other Unidrive SP sizes (from the compact SP0202 up to high-power SP5402 units), the SP1405 lets engineers standardize commissioning knowledge across projects using multiple drive frame sizes.
