Voltage Rating: 400V (3-phase input, compatible with 230V, 460V, 575V, and 690V options in the Unidrive SP range)

Current Ratings:

Maximum Heavy-Duty Current: 5.8 Kc A (continuous operation under heavy loads)

Maximum Normal-Duty Current: 6.9 A (standard operating conditions)

Switching Frequency: 16 kHz (reduces motor noise and improves efficiency)

Control Modes:

Vector Control (SVC): For high-precision torque and speed regulation.

V/F Control: Simplified operation for standard applications.

Position Control: Supports encoder feedback for precise positioning tasks.

Communication Interfaces:

Industrial Protocols: Modbus RTU, CANopen, DeviceNet, Profibus DP, and Ethernet/IP (optional).

Fieldbus Integration: Seamless connectivity with PLCs, HMIs, and SCADA systems.

Core Features

1.High Dynamic Performance

Rapid response to load changes (<10ms), ensuring stability in high-speed machining or automation lines.

Supports motor speeds up to 20,000 RPM (depending on motor type).

2.Industrial-Grade Reliability

Operating Temperature: -10°C to +50°C (with derating up to +60°C).

Protection: IP20 enclosure (dust-resistant), short-circuit, overvoltage, and overcurrent safeguards.

Certifications: CE, UL, cUL, and RoHS compliant for global market access.

3.Modular Design

Compact footprint saves panel space (dimensions: 145mm × 250mm × 210mm).

Optional plug-in modules for I/O expansion, safety functions, or additional communication protocols.

4.Energy Efficiency

Built-in energy-saving algorithms reduce power consumption by up to 30% in partial-load scenarios.

Supports regenerative braking (with optional braking resistors) to recover kinetic energy.

5.User-Friendly Interface

Keypad: Backlit LCD display with multilingual support for easy parameter configuration.

Software: Unidrive Connect PC tool enables remote monitoring, diagnostics, and firmware updates.

Applications

• Material Handling: Conveyors, cranes, and hoists requiring precise load control.
• HVAC Systems: Fans, pumps, and compressors with variable torque demands.
• Packaging Machinery: Labeling, filling, and sealing equipment needing synchronized motion.
• Metalworking: Lathes, milling machines, and CNC systems demanding high-speed accuracy.
• Renewable Energy: Solar tracking systems and wind turbine pitch control.

Technical Support & Warranty

• Global Network: CONTROL TECHNIQUES (now part of Nidec Industrial Automation) offers 24/7 technical support via 23 Drive Centers worldwide.
• Warranty: 2-year standard warranty (extendable up to 5 years with service contracts).
• Legacy Transition: The SP1404 is part of the Unidrive SP series, which is being phased out in favor of the newer Unidrive M line. However, spare parts and repairs remain available until 2035.
