YOKOGAWA AFV30D-S41252

2. Product introduction

The YOKOGAWA AFV30D-S41252 is a high-performance variable frequency drive in YOKOGAWA’s AFV30D series, tailored for medium to large industrial motor control where single-phase power is available. It shares core functionalities with the AFV30D-A41252 but is designed to operate with single-phase input, making it suitable for facilities with limited three-phase power infrastructure.

This drive adjusts output frequency and voltage to control AC induction motor speed, torque, and power, supporting V/f control, sensorless vector control, and closed-loop vector control with an encoder. The AFV30D-S41252 is ideal for industries like food processing, small-scale manufacturing, and regional water treatment plants where single-phase power is prevalent. By combining high power handling with single-phase compatibility, the YOKOGAWA AFV30D-S41252 enables precise motor control and energy efficiency in applications where three-phase power isn’t readily accessible.

3. Core advantages and technical highlights

Single-phase input with high power output:

A key distinction from the three-phase AFV30D-A41252, the AFV30D-S41252 accepts single-phase 200-240V input while delivering 11kW output, making it unique for powering large motors in single-phase environments. In rural manufacturing facilities or small water treatment plants with limited three-phase infrastructure, this eliminates the need for costly phase converters. It efficiently converts single-phase to three-phase power, maintaining stable output even with input voltage fluctuations common in single-phase grids.

Consistent precision control:

Like the AFV30D-A41252, the AFV30D-S41252 offers closed-loop vector control with an encoder, achieving a 1:1000 speed range and ±0.01% accuracy. This makes it suitable for precision applications such as automated packaging lines in food processing, where synchronized conveyor speeds ensure uniform packaging. The sensorless vector mode provides reliable low-speed torque for mixers or agitators, maintaining consistent performance without encoder feedback when precision demands are slightly lower.

Flexible communication integration:

Equipped with the same RS-485, Ethernet/IP, and PROFINET interfaces as the AFV30D-A41252, the AFV30D-S41252 seamlessly integrates into complex networks. In a distributed facility with single-phase power, multiple AFV30D-S41252 drives can connect via PROFINET to a central PLC, enabling coordinated operation of pumps, conveyors, and mixers. This connectivity simplifies remote monitoring, reducing on-site maintenance needs in scattered facilities.

Robust design for diverse environments:

The AFV30D-S41252 features the same rugged construction as its three-phase counterpart, with conformal-coated circuit boards and -10°C to 55°C operating range. Its comprehensive protection suite, including ground fault and overload protection, ensures durability in dusty workshops or outdoor installations. This resilience minimizes downtime, critical for single-phase-reliant facilities where equipment redundancy is often limited.

4. Typical application scenarios

In regional water treatment plants with single-phase power, the AFV30D-S41252 controls 11kW centrifugal pumps, adjusting speed based on water demand. Its single-phase compatibility eliminates the need for expensive three-phase upgrades, while closed-loop control maintains consistent pressure, preventing pipe damage. During peak hours, it ramps up smoothly to handle increased flow, then reduces speed during lulls, cutting energy use by up to 25% compared to fixed-speed systems.

In food processing facilities with single-phase infrastructure, the AFV30D-S41252 regulates conveyor and mixer speeds. For bakery dough mixers, sensorless vector control provides steady low-speed torque to prevent ingredient separation, while Ethernet/IP integration with HMI systems allows operators to adjust speeds remotely for recipe changes. Its compact design fits into stainless steel control cabinets, meeting hygiene standards while withstanding washdown environments.

In rural manufacturing workshops, the AFV30D-S41252 powers 11kW lathes and milling machines. Its ability to handle single-phase input enables these facilities to use modern variable-speed machinery without three-phase power, improving precision in metalworking. Closed-loop control ensures consistent spindle speeds, enhancing part quality, while overload protection prevents damage during heavy cuts, extending machine life.

6. Installation, commissioning and maintenance instructions

Installation preparation

Before installing the AFV30D-S41252, confirm the single-phase input supply (200-240V) is stable and properly grounded, with a dedicated circuit to avoid voltage drops. Ensure the mounting location has 150mm clearance above/below for cooling, away from direct sunlight and moisture. Tools needed include a torque screwdriver (1.5-3.0Nm), wire strippers, and a clamp meter for current checks.

Use shielded cables for motor and encoder connections, grounding the shield at both ends to reduce noise. Install a 40A circuit breaker upstream for protection. During wiring, separate power and control cables to minimize interference. Enter accurate motor parameters (voltage, current, speed) during commissioning to optimize the AFV30D-S41252‘s performance with the connected motor.

Maintenance suggestions

Inspect the AFV30D-S41252 monthly for loose connections, dust buildup, or overheating signs. Clean the heat sink and vents with compressed air every two months, more frequently in dusty areas. Check single-phase input voltage regularly to ensure it stays within 200-240V, as fluctuations can affect performance.

Monitor fault codes via the display or HMI: overvoltage may indicate input supply issues, while overcurrent could signal a motor or cable problem. Replace the cooling fan every 3-4 years using YOKOGAWA-approved parts. Back up parameters to a USB drive quarterly, especially after adjustments, to simplify recovery. For single-phase-specific issues, verify input phase integrity and check for neutral conductor faults, which are critical in single-phase systems.
