YASKAWA Frequency Converter Product Introduction

YASKAWA frequency converters are devices used to regulate the speed and torque of electric motors, widely applied in the field of industrial automation. They adjust the operating speed of the motor by changing the power frequency, thereby achieving precise control of the motor. These devices are typically used to improve energy efficiency, reduce energy consumption, and enhance the stability and precision of the production process.

Features of YASKAWA Frequency Converter Products

High Performance

They exhibit excellent control performance, capable of precisely controlling the speed of motors, whether in low-speed or high-speed operating states, maintaining stable output. For example, in CNC machines, automated production lines, and other equipment with high-speed accuracy requirements, YASKAWA frequency converters can meet their stringent control demands.

High Reliability

With exquisite design and manufacturing processes, they offer high reliability and stability, capable of long-term stable operation in various complex industrial environments. The failure rate of YASKAWA frequency converters is relatively low, reducing downtime and maintenance costs.

Excellent Energy Saving

Some models of YASKAWA frequency converters feature super energy-saving characteristics, efficiently driving induction and synchronous motors, ensuring normal motor operation while minimizing energy consumption, thus saving energy costs for users.

Ease of Operation

Equipped with user-friendly interfaces and parameter setting methods, users can easily debug and operate the devices. In addition, they support visual programming functions, allowing users to customize the functions of YASKAWA frequency converters according to their needs.

Strong Environmental Adaptability

YASKAWA frequency converters are resistant to humidity, dust, oil, and vibration, making them suitable for various harsh working environments such as factory workshops, mines, and ports.

Common Faults and Solutions for YASKAWA Frequency Converters

Switching Power Supply Damage

This is one of the most common faults of inverters, usually caused by a short circuit in the load of the switching power supply. During maintenance, the load circuit of the switching power supply needs to be checked, and after eliminating the short circuit fault, the damaged switching power supply components should be replaced.

OH Overheat Fault

When this fault occurs, the cooling fan should be checked first to see if it is operating. For machines above 30kW, there is an internal cooling fan as well; failure of this fan can also lead to an OH alarm. If the fan is normal, it may be that the heat dissipation channel inside the inverter is blocked or the heat sink is too dusty, requiring cleaning of the heat dissipation channel and heat sink.

UV Undervoltage Fault

When an undervoltage fault occurs, first check whether the input power supply is missing a phase. If the input power supply is fine, then check if there is an issue with the rectification circuit. If the rectification circuit is normal, then check for problems on the DC detection circuit. For 200V-class machines, a UV alarm will occur when the DC bus voltage is below 190Vdc; for 400V-class machines, a fault alarm will occur when the DC voltage is below 380Vdc.

As a key device for efficient energy saving, YASKAWA frequency converters are widely used in modern industrial automation, providing vital technical support to the production process.
