Key Features and Advantages
The ARND-3110N delivers precision motor control in a space-efficient design, featuring auto-tuning capabilities that reduce commissioning time by 50% compared to basic VFDs. Its advanced current-limiting algorithm prevents nuisance tripping during abrupt load changes, maintaining production continuity in packaging applications. The built-in PLC functionality supports simple logic operations without external controllers, ideal for standalone conveyor systems.
Energy-saving modes optimize consumption during light-load conditions, achieving up to 25% power reduction in ventilation systems. The drive’s robust design withstands voltage fluctuations up to ±15%, ensuring stable operation in rural power grids. A user-friendly keypad with 16-character LCD provides quick parameter access and real-time monitoring of critical parameters like motor torque and DC bus voltage.
Application Areas
In agricultural irrigation systems, the ARND-3110N precisely controls deep-well pump speeds to maintain water pressure within ±5% of setpoints. Small-scale manufacturing lines utilize its compact size for integration into CNC machine tool cabinets, reducing footprint by 40%. Textile factories deploy this drive for spindle motor control in weaving machines, where its quick acceleration/deceleration profiles prevent yarn breakage.
Commercial laundry equipment benefits from the drive’s built-in PID loop for temperature-controlled steam generation. The RS-485 interface enables centralized monitoring of multiple compressors in refrigeration plants, while the optional Modbus RTU connectivity supports integration with building management systems.

Installation and Maintenance
Installation preparation: Mount the ARND-3110N on a flat vertical surface with ≥50mm side clearance for ventilation. Use shielded cables for control signals and maintain 30cm separation from power lines. Configure motor parameters using the auto-tuning wizard before initial operation.
Maintenance recommendations: Clean cooling fins biannually using low-pressure air (<0.2 MPa). Check terminal tightness annually (1.2 Nm torque). Update firmware via USB port during planned downtime. Monitor capacitor health through the drive’s self-diagnostic menu (replace if ESR > 1Ω).
Product Assurance
Every ARND-3110N undergoes 48-hour burn-in testing with simulated load cycling. Our regional service centers provide next-business-day replacement for defective units under warranty. Complimentary access to Toshiba DriveCare™ portal includes lifetime firmware updates and troubleshooting guides. On-site training packages ensure proper utilization of advanced features like PID fine-tuning and multi-step speed programming.
