Product Description:
The 131B0477 drive is designed for industrial automation tasks. It belongs to the VLT FC 302 Automation Drives series by Danfoss manufacturer. It is known for its reliability and high protection features in motor control applications. This drive refers to the product FC-302P7K5T5E20H1BGXXXXSXXXXA0BXCXXXXD0.
The Danfoss 131B0477 has a rated output of 7.5 kW. It has a voltage supply range of 3 x 380 to 480 volts AC at 50 or 60 Hz. The drive may be placed at altitudes of up to 1000 meters without derating. This drive has an output current of 16 amps at normal load and 13.2 amps at heavy duty. The overload capacity is 110% for one minute in regular duty and 160% for one minute in heavy duty operation. This model's common frame size is B1 or B2, allowing for simpler incorporation with automation panels. The drive has two relay outputs with typically open and normally closed contacts. There are two analog inputs that can be set to either 0–10 volts or 0/4–20 milliamps. One analog output is supplied which is capable of operating at 0/4–20 milliamps with a maximum load of 500 ohms. Up to six digital inputs or outputs can be programmed for specific control requirements. Motor cable lengths can be up to 150 meters when shielded and 300 meters when unshielded. The enclosure type for this drive is IP20 which provides protection against solid objects. The Danfoss Drive incorporates Safe Torque Off (STO) on terminal 37 for added safety.
The 131B0477 drive can work in temperatures ranging from -10°C to +50°C. There is a requirement to derate above 40 degrees Celsius. It has a built-in RFI filter that fulfills the EN 61800-3 industrial standard. Conductors with a cross-section ranging from 0.25 mm² to 1.5 mm² are compatible with the control terminal wiring. It provides Class 20 motor overload protection, integrated ground fault prevention and short-circuit and overcurrent protection via external fusing.
Frequently Asked Questions about 131B0477:
Q: How do the relay outputs of product code 131B0477 Drive support automation?
A: Dual relay outputs provide versatile interfacing with external alarms or status systems. This supports automated process feedback and interlock operations.
Q: What is the role of electronic motor overload protection in the drive?
A: Electronic overload protection monitors motor current and responds to overloads. This helps prevent overheating and potential damage to both the motor and drive.
Q: How do analog inputs in 131B0477 Drive assist process control?
A: Analog inputs allow direct connection to sensors and control devices. This provides real-time process feedback for precise speed or torque regulation.
Q: How does altitude affect the performance of this drive?
A: Operation above 1000 meters requires derating to ensure thermal protection. Proper derating helps maintain efficiency and reliability in high-altitude installations.
Q: Why is a maximum output frequency of 590 Hz provided in this series?
A: The high output frequency supports applications requiring variable speed and specialized motor types. It enables the use of high-speed or special purpose motors.
