Product Description:
The 131Z8972 is an AC variable-frequency drive produced by Danfoss for the VLT 2800 Low Voltage Drives series. It regulates the speed of small induction motors by converting fixed-frequency supply power into a controlled output waveform, allowing precise torque control in conveyor, pump, and mixer stations across automated process lines. The compact unit mounts inside control cabinets and provides local access to operating parameters through its integrated keypad and display. This interface allows operating values and drive status information to be viewed directly at the cabinet.
It draws power from a 200–240 V AC mains supply and is wired for single-phase operation, making it suitable for facilities without three-phase service. The drive carries an IP20 protection rating, so live parts are shielded against accidental contact, but the unit must remain inside a closed enclosure. An integral EN 55011 Class A1 RFI filter suppresses conducted electrical noise, helping the installation meet industrial emission limits without a separate filter. The factory configuration is standard with a brake, enabling connection to a brake resistor so the motor can decelerate quickly during controlled stops. This braking arrangement helps manage regenerated energy when the connected motor slows rapidly or operates with a high-inertia load.
The drive uses a compact book-style enclosure that conserves panel width and aligns its cooling channels with adjoining modules. A built-in display (SLCP) reports setpoints, feedback values, operating conditions, and alarm codes, eliminating the need for a remote keypad during setup. The control board has a protective coating that shields solder joints and electronic components from moisture and airborne contaminants found in washdown or chemical processing areas. The unit is configured for process applications, with default parameter settings that support constant-torque loads at low speeds. No application option card or fieldbus option is installed, so communication with an industrial network requires an external gateway. The open enclosure design also requires adequate cabinet ventilation and clearance around the cooling passages to prevent excessive internal temperatures during continuous operation.
