The sander is equipped with a “tailor-made” ideal inverter to meet customers’ multiple needs for reliability, uptime, user friendliness and support.

Guangdong Moke Technology Co., Ltd. is located in Foshan City, Guangdong Province, China, is a production of sander machinery manufacturer. The company’s sanders help furniture and parts makers in China and Southeast Asia complete sophisticated automated sanding processes, including sanding and polishing wooden furniture components, such as kitchen cabinets and doors, before being assembled into complete furniture.
Each sander usually has a conveyor belt, usually carrying rough, semi-finished wooden or composite parts to one end of the belt and sending the surface out the other end after a fine sanding and polishing. A typical sander typically uses two 2.2-KW motors to drive the conveyor belt. The furniture is sanded by 10 sanding pans inside the machine, which gradually sand the surfaces of the pieces as they move along the conveyor belt. The frosted disks are powered by 10 1.5kW motors, whose speed and torque are tightly controlled by ABB compact ACS180 frequency converters.

Shock overload was a major challenge

Prior to the use of ACS180 converters, the main problem faced by customers was that the motor load suddenly fluctuated and the other brands controlling the motor were unable to compensate for these load changes, resulting in frequent frequency failures of the converters.

Previous converters do not have sensorless vector control performance, so the motor speed can be significantly reduced or even overloaded. This problem can lead to uneven sanding on the surface of furniture parts and affect the quality, and even the accidental failure of frequency converter may occur, leading to shutdown and affecting work efficiency.

The machine runs in good condition, which relieves customers from worries
In order to solve the problem of sanding opportunities and to save furniture manufacturers from having to worry about sanding machines, Guangdong Mok Technology decided to use ABB’s latest ACS180 compact frequency converter, which is specially designed for this type of application.

One of the key features of the ACS180 compact frequency converter is the built-in sensorless vector control mode, which enables the sanding process to be refined and reduces the accidental failure rate of the sander, further improving customer machine productivity and product quality.

Compact and easy to use

In addition, the compact size of the ACS180 converter makes it easy to install into the sanding cabinet where the previous converter was located, eliminating the need to redesign the machine structure, helping customers save time and cost. In addition, the ACS1 80 frequency converter is also standard with a variety of features, such as built-in Modbus interface and integrated safety-safe torque cancellation (STO) function, which contributes greatly to the design and manufacture of the machine.

Win high praise from customers

Mr. Yang Guiquan, General Manager of Guangdong Moke Technology Co., Ltd. introduced the benefits of the new equipment. “Before we started using the ACS180, there was a risk of overload,” he says. “This risk caused the machine to grind at abnormal speeds and even to stop unexpectedly during the grinding process. Therefore, we have been looking for a frequency converter manufacturer that can help us improve operational reliability and user friendliness, as well as provide good local service when necessary.

After replacing the inverter, we found that ACS180 has excellent performance, high torque stability and strong overload capacity. It can make the grinding process more fine and reduce the accident failure rate of the sander. In addition, ABB brand influence and product compact appearance also add highlights to the sander.

The ACS180 is easy to use, and the handheld assistant control panel makes debugging more convenient. Its ease of installation and use greatly reduces the workload of the customer’s technical team. ABB drives and its channel partners are ready to provide support when necessary. In addition, ACS180 is cost-effective and can bring more value to customers.
