Design and Performance
Highest-Power Standard Configuration in the SP140x Sub-Range
At 3 kW / 5 HP Normal Duty with 6.9 A continuous output, the SP1404 delivers the top power rating within the SP1401–SP1404 braking resistor group, suiting the more demanding motor applications available within the compact Frame Size 1 platform.
Obsolete Platform Still Widely Supported for Maintenance
Nidec has officially declared the entire Unidrive SP series obsolete, but the SP1404 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.
Encoder Feedback Support for Closed-Loop Precision
Supporting both incremental and absolute encoder types, this drive enables closed-loop vector or servo control modes for applications requiring precise speed and position regulation beyond open-loop control.
Defined Braking Resistor Compatibility for Dynamic Stopping
Rated for a minimum 74 Ω braking resistor with 8.3 kW instantaneous power capability (shared with the SP1401-SP1404 sub-range), this drive supports properly matched dynamic braking for applications requiring rapid, controlled deceleration.
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 SP1404 lets engineers standardize commissioning knowledge across projects using multiple drive frame sizes.
