YOKOGAWA VF701

Product Introduction

YOKOGAWA vf701 is a compact yet powerful AC drive designed to precisely control the speed and torque of 3-phase induction motors in industrial applications. As part of YOKOGAWA’s renowned variable frequency drive lineup, this 1.5kW inverter combines advanced motor control technology with user-friendly operation, making it suitable for both simple and complex motion control tasks.

The vf701 integrates seamlessly into automation systems, providing efficient motor control that reduces energy consumption while maintaining precise performance. Its dual control modes (V/f and sensorless vector) allow adaptation to various load types, from fans and pumps to conveyors and mixers. In industrial setups, vf701 acts as a critical interface between control systems (like PLCs) and electric motors, translating control signals into smooth, adjustable motor operation that enhances process efficiency and equipment lifespan.

Core Advantages and Technical Highlights

Energy efficiency: YOKOGAWA vf701 incorporates advanced energy-saving algorithms that optimize motor performance based on load demands. In a centrifugal pump application, it can reduce energy consumption by up to 30% compared to traditional motor control methods by adjusting speed to match flow requirements rather than using throttle valves. This efficiency not only lowers operational costs but also reduces carbon footprint.

Flexible control options: With both V/f and sensorless vector control, the vf701 adapts to diverse industrial needs. Sensorless vector control delivers high starting torque (150% at 0.5Hz) for applications like conveyor belts starting under heavy loads, while V/f control provides stable operation for fans and pumps. This versatility eliminates the need for multiple drive types in a single facility.

Compact design with robust construction: Measuring just 140mm in width, the vf701 saves valuable cabinet space while maintaining durability. Its rugged design withstands harsh industrial environments with protection against dust, vibration, and temperature fluctuations. The drive’s comprehensive protection features prevent damage from electrical faults, ensuring reliable operation in critical applications.

User-friendly operation: The vf701 features an intuitive keypad and digital display for easy parameter setup and monitoring. It supports copy/paste of settings between drives, simplifying commissioning in multi-drive systems. The built-in RS-485 communication allows for remote monitoring and control via SCADA or PLC systems, reducing the need for on-site adjustments.

Typical Application Scenarios

In food and beverage processing plants, YOKOGAWA vf701 controls conveyor systems that transport products between processing stages. Its precise speed control ensures gentle handling of delicate items, while sensorless vector control provides the torque needed to start fully loaded belts. The drive’s easy cleaning design and protection against liquid ingress make it suitable for washdown environments.

Within water treatment facilities, the vf701 regulates pump motors in filtration systems, adjusting speed based on water demand. This not only saves energy but also reduces mechanical stress on pumps, extending equipment life. The drive’s ability to operate in variable torque mode makes it ideal for matching pump performance to fluctuating system pressures.

In packaging machinery, vf701 controls the speed of wrapping and labeling equipment, ensuring synchronization with production lines. Its fast response to control signals allows for quick adjustments during format changes, minimizing downtime when switching between product types.

Installation, Commissioning and Maintenance Instructions

Installation preparation: Before installing YOKOGAWA vf701, ensure the mounting location provides adequate ventilation (minimum 100mm clearance above and below). Use appropriate tools including torque screwdrivers (0.5-1.5Nm) and wire strippers. Verify input voltage matches the drive’s specifications and install proper fuses or circuit breakers. Use shielded cables for motor connections, grounding the shield at both ends to reduce electromagnetic interference. Mount the drive vertically on a flat, non-combustible surface to ensure proper heat dissipation.

Maintenance suggestions: Inspect vf701 monthly for dust accumulation, cleaning with compressed air if necessary. Check connections quarterly to ensure tightness, especially after initial operation. Monitor drive temperatures during operation to prevent overheating. In case of faults, refer to the error code display for troubleshooting—common issues like overcurrent may indicate motor overload or wiring problems. Replace cooling fans every 3-5 years as preventive maintenance, using only genuine YOKOGAWA parts to maintain performance and safety.
