Buy online your DANFOSS 131B0520 Variable-frequency drives from our e-store Cnc-shopping, specialist in CNC machine-tools spare parts.

The DANFOSS 131B0520 is a variable-frequency drive (VFD) designed to control three-phase AC motors in industrial machinery and CNC equipment. Rated at 1.5 kW / 2 HP, it provides adjustable motor speed and controlled acceleration and deceleration for pumps, fans, chip conveyors, coolant systems and other machine-tool auxiliaries.

This DANFOSS AC drive features a 3-phase 380–500 V input and supports an output frequency range of 0–590 Hz. The rated input current is 3.7/3.1 A, while the output current is 4.1/3.4 A, with ratings specified for HO and NO duty. Manufactured in Denmark, the 131B0520 is suitable for panel-mounted installation in industrial and CNC control cabinets.

The 131B0520 is a practical replacement unit, spare part or CNC replacement component for maintenance and retrofit applications. It can replace a faulty drive affected by output loss, drive trips or unstable motor control when the voltage, motor power, I/O configuration and parameters match the existing installation.

Each unit supplied by Cnc-shopping can be inspected and function-tested on suitable drive test equipment before shipment. Units are professionally packaged for industrial transportation and supplied with a commercial warranty, with worldwide shipping and fast dispatch depending on availability.

The DANFOSS 131B0520 can also be kept as an emergency spare for legacy CNC and automation systems. Cnc-shopping can assist with sourcing obsolete parts and may provide repair or exchange services when applicable, helping reduce machine downtime and extend the service life of existing equipment.

Frequently asked questions about 131B0520:

Is the 131B0520 suitable for standard three-phase induction motors rated at 1.5 kW / 2 HP?
Yes, it is designed for that power class. Verify your motor nameplate and cabinet supply requirements to confirm suitability before installation.

How is this DANFOSS drive typically commanded in a CNC cabinet?
It commonly receives a run command from the CNC or PLC and a speed reference from the control system. Check your wiring diagram and the drive terminals to align I/O with your existing configuration.

Can it replace an older VFD of the same power in a drop-in manner?
In many cases yes, provided the voltage class, I/O logic and mounting constraints match. Review the part number and compare parameters to minimize changes during the swap.

Where is this drive most often used on machine tools?
It is frequently assigned to coolant pumps, chip conveyors, lubrication or hydraulic support motors and spindle cooling fans. These loads benefit from adjustable speed and controlled acceleration to protect mechanical components.

Do you offer support if the original model is obsolete?
Cnc-shopping can help with equivalent sourcing, tested unit supply and repair service options when available. Contact us with the cabinet details and motor data for guidance.
