Design and Performance
Highest-Power Configuration in the SP140x Frame Size 1 Range
At 5.5 kW / 7.5 HP Normal Duty with 11 A max. continuous output, the SP1406 delivers the top power rating within the SP140x sub-range, suiting demanding CNC, robotics, and automated assembly line applications requiring high torque and precise speed control.
Full Five-Mode Operation Including Regen
Beyond standard open loop, RFC, closed loop vector, and Servo modes, the SP1406 also supports Regen operation, giving engineers additional flexibility for applications requiring regenerative braking or four-quadrant operation.
Obsolete Platform Still Widely Supported for Maintenance
Nidec has officially declared the entire Unidrive SP series obsolete, but the SP1406 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.
Broad Feedback Device Compatibility for Precision Applications
Supporting encoders, resolvers, and other feedback devices, the SP1406 enhances precision and responsiveness for demanding servo applications such as CNC machines and robotics requiring high torque and precise speed control.
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 SP1406 lets engineers standardize commissioning knowledge across projects using multiple drive frame sizes.
