Installation requirements and on-site commissioning precautions for RVE35 Low Voltage Variable Frequency Drive

Fujian Raynen Technology Co., Ltd., established in 2007 and listed on the Shanghai Stock Exchange (stock code: 603933) in 2017, is a leading domestic supplier of industrial automation products. With its headquarters in Fuzhou and nearly 20 subsidiaries across China, the company has built a strong reputation through continuous innovation and technological advancement. As a "Key High-tech Enterprise of the National Torch Program," Raynen Technology has developed numerous patented technologies and core solutions in control and drive systems. Its product portfolio includes AC servo systems, programmable logic controllers (PLCs), human-machine interfaces (HMIs), IoT gateways, and variable frequency drives (VFDs), such as the RVE35 series.

The RVE35 Low Voltage Variable Frequency Drive , designed by Raynen Technology, is a high-performance VFD tailored for general automation applications in industries such as textiles, machine tools, logistics, and more. It offers precise motor speed control, energy efficiency, and enhanced system stability. However, to ensure optimal performance and safety during installation and commissioning, certain requirements and precautions must be strictly followed.

1.Installation Requirements for RVE35 VFD

1)Environmental Conditions

The installation environment plays a crucial role in ensuring the long-term reliability and performance of the RVE35 VFD. The following environmental conditions should be met:

Ambient Temperature: -10°C to +50°C (with derating above 40°C).

Humidity: Below 90% RH (non-condensing).

Dust and Contaminants: Avoid installing the drive in areas with excessive dust, corrosive gases, or oil mist.

Vibration and Shock: Ensure that the installation location is free from excessive vibration or mechanical shock.

Raynen Technology recommends installing the RVE35 in an enclosed cabinet equipped with proper ventilation and cooling systems, especially when used in harsh industrial environments.

2)Electrical Installation

Proper electrical wiring is essential to prevent damage and ensure safe operation. Key considerations include:

Power Supply Specifications: The RVE35 operates on a low voltage input range of 220VAC to 480VAC, single-phase or three-phase, depending on the model.

Wiring Standards: Follow national and international electrical codes (e.g., GB/T, IEC) for cable sizing, grounding, and insulation.

Grounding: A reliable ground connection must be provided to protect against electric shock and electromagnetic interference (EMI).

Separation of Power and Signal Cables: To avoid signal interference, power cables and control signal cables should be routed separately and at right angles where possible.

Raynen’s technical support team provides detailed wiring diagrams and installation guidelines specific to each application scenario.

3)Mechanical Installation

Mounting Orientation: Install the RVE35 vertically to ensure adequate airflow and heat dissipation.

Clearance Requirements: Maintain sufficient clearance around the drive—typically 10 cm on both sides and 15 cm on top and bottom—to allow for proper ventilation.

Cabinet Cooling: In high-temperature environments, use fans or air conditioning units to maintain internal cabinet temperatures within the allowable range.

2.On-site Commissioning Precautions

Commissioning the RVE35 VFD involves configuring the parameters and testing the system under real operating conditions. This process must be carried out carefully to avoid equipment damage or operational issues.

1)Pre-commissioning Checks

Before powering up the system, perform the following checks:

Visual Inspection: Ensure there are no signs of physical damage to the drive unit or wiring.

Tightness of Terminals: Verify that all terminal connections are secure and properly tightened.

Motor Connection: Confirm that the motor is correctly connected to the output terminals (U, V, W) and that the motor rating matches the drive specifications.

Control Wiring: Check that all control signals (start/stop, analog inputs, etc.) are wired according to the control schematic.

2)Parameter Configuration

Raynen Technology's RVE35 VFD features user-friendly parameter settings via the built-in keypad or external software tools. During commissioning, the following parameters should be configured carefully:

Motor Parameters: Enter the rated voltage, current, power, and speed of the motor.

Control Mode: Select the appropriate control mode (V/F, sensorless vector, or closed-loop vector) based on the application.

Acceleration/Deceleration Time: Set these values according to the load characteristics to prevent overcurrent or overvoltage faults.

Protection Settings: Configure protection functions such as overcurrent, overvoltage, undervoltage, and overheating.

Raynen provides comprehensive commissioning manuals and on-site support services to assist engineers in optimizing these settings.

3)Trial Operation

Once the configuration is complete, conduct a trial run under no-load or light-load conditions:

Monitor Display: Observe the drive display for any fault codes or abnormal readings.

Check Motor Rotation: Ensure the motor rotates in the correct direction; if not, swap two output phases.

Listen for Unusual Noise: Detect any unusual vibrations or noises that may indicate incorrect alignment or faulty components.

Thermal Testing: Use thermal imaging equipment to check for overheating in cables or connections.

4)Fault Diagnosis and Troubleshooting

In case of faults or alarms during commissioning, refer to the troubleshooting section of the manual or contact Raynen Technology’s technical support center. Common issues include:

E.OV (Overvoltage): Check the deceleration time and braking resistor (if applicable).

E.OC (Overcurrent): Review acceleration time and motor load.

E.UV (Undervoltage): Inspect the input power supply stability.

Raynen's customer service team is available 24/7 to provide remote diagnostics and on-site assistance when needed.
