Siemens 3RW4026-1BB04 frequency converter

Product Detailed Description:

The Siemens 3RW4026-1BB04 is a frequency converter (also known as an AC drive or VFD - Variable Frequency Drive) from the SINAMICS G110 series. It is designed for the simple and cost-effective control of asynchronous motors in a wide range of applications. This specific model is a compact, single-phase input device, making it suitable for smaller motor drives where three-phase power is not available or desirable. It allows users to control motor speed, torque, and direction by varying the frequency and voltage supplied to the motor, offering significant energy savings and improved process control compared to traditional on/off control methods.

Product Parameters (Typical for this type, specific values vary by model within the G110 series):

• Rated Motor Power: Typically around 0.75 kW / 1 HP (Verify specific datasheet for exact value)

• Rated Motor Current: Typically around 2.3 A (Verify specific datasheet for exact value)

• Supply Voltage: Single-phase AC 200-240 V (±10%)

• Nominal Output Voltage: Three-phase AC 3 x 230 V

• Nominal Output Current: Typically around 2.6 A (Verify specific datasheet for exact value)

• Control Methods: V/f control (Voltage/frequency)

• Protection Rating: IP20 (for the unit itself)

• Communication: Basic control via terminals (start/stop, direction, speed reference)

• Enclosure: Open-type unit, typically mounted in a control cabinet or directly on the machine

Product Advantages:

• Cost-Effective: Designed for simple applications at a competitive price point.

• Energy Saving: Allows motors to operate only at the required speed, reducing energy consumption significantly compared to constant speed operation.

• Compact Design: Particularly suitable for applications with limited space, especially the single-phase input version.

• Simple Operation and Installation: Basic parameterization and straightforward wiring make it easy to use.

• Smooth Start/Stop: Reduces mechanical stress on the motor and connected machine components, extending equipment life.

• Process Control: Enables precise control of speed and torque, improving process quality and flexibility.

• Single-Phase Input Capability: Widely applicable where only single-phase power is available.

Precautions / Important Notes:

• Electrical Safety: High voltages are present. Installation, commissioning, and maintenance must only be carried out by qualified personnel. Strictly follow all safety instructions in the operating manual.

• Correct Motor Connection: Ensure the motor is correctly connected to the three-phase output terminals (U, V, W). Connecting to the single-phase input terminals (L1, N) will damage the drive.

• Derating: Do not exceed the rated motor power and current. Derating may be required at high ambient temperatures or altitudes.

• Harmonics and EMC: The drive generates harmonics and electromagnetic interference. Ensure proper earthing, shielding of cables, and use of appropriate filters if required by the application or regulations.

• Overheating: Ensure adequate ventilation and do not block the cooling fins or fan. Operate within the specified ambient temperature range.

• Parameter Settings: Incorrect parameter settings can lead to motor damage or improper operation. Only change parameters if you understand their function.

• Read the Manual: Always consult the specific operating and installation manual for the 3RW4026-1BB04 before installation or operation.

Product Applications:

The SINAMICS G110, including the 3RW4026-1BB04, is widely used in applications requiring simple motor control and energy savings, particularly where single-phase power is common. Typical applications include:

• Pumps: Water supply, heating/cooling systems, wastewater treatment.

• Fans: HVAC (Heating, Ventilation, and Air Conditioning) systems, industrial ventilation.

• Compressors: Air or refrigerant compressors.

• Conveyors: Small belt conveyors, packaging lines.

• Machine Tools: Feeding mechanisms, spindle drives in simpler machines.

• Small Hoists and Cranes: For lifting applications requiring variable speed.

• Food and Beverage Industry: For driving mixers, pumps, and small conveyors.

• Domestic and Light Commercial Equipment: Where compact and cost-effective speed control is needed.
