Product Description:

The 131B0487 is a high-performing frequency converter that is designed by Danfoss Automation to meet industry demand for a product that provides accurate control of three-phase servo motor units while maintaining an impressive electrical efficiency and accuracy. This converter is able to produce a power output of 7.5 kilowatts from connected motor units. It comes with a Graphical Local Control Panel (LCP) through which operation status can be monitored and command instructions can be sent in real time. The 131B0487 frequency converter is classified under the IP20 protection category. It is designed to be used inside a control cabinet that can protect it from external interference. A Radio Frequency Interference (RFI) is built into this product from the factory; this is crucial in preventing high-frequency signals from interfering with the operation of the unit. There is no brake chopper or mains option installed with this product.

The 131B0487 frequency converter requires a consistent voltage supply that falls between 380 to 500 volts, it can supply an output voltage up to 100 percent of its supply voltage without problem. During operation, this unit will easily withstand mains fluctuations like transients, momentary dropouts, short voltage drops, and surges. The converter also uses resonance damping to eliminate motor resonance noise during operation. The temperature inside this product is controlled by internal cooling fans; the operation of these fans depends on the current temperature status of the product. To conserve energy, the fans are not running during low load operation, or when it is sleep mode or standby mode.

The 131B0487 frequency converter provides motor thermal protection by directly sensing the temperature in the thermistor in the motor winding. It can also provide this protection through the use of built-in electronic Thermal Relay (ETR).
