175Z0067 by Danfoss

The 175Z0067 frequency converter is manufactured by Danfoss and belongs to the VLT 5000 Frequency Converters series. Designed for use in industrial automation, the unit modulates the voltage and frequency supplied to three-phase induction motors so production machinery, pumps, or fans can run at precisely commanded speeds. By varying motor speed rather than relying on mechanical throttling, it supports energy savings, reduces mechanical wear, and allows processes to match load demands in real time. This makes the drive suitable for applications that need adjustable motor speed without changing the incoming power source.

It accepts a 380-500 V three-phase supply, which lets the converter interface directly with common industrial mains without an input transformer. Output capability is given in two overload regions: continuous processes can draw up to 7.5 kW at 110% torque, while short-term high-inertia loads can reach 5.5 kW at 160% torque. Electromagnetic compatibility is supported by the integrated Class A1 and B filter, and control logic resides on a modular Process control card that supports closed-loop regulation from process signals rather than simple open-loop speed commands. The unit uses non-coated boards, and the drive is shipped with no built-in option so an open slot remains available for user-specific extensions.

There is no display, so local parameter access must be performed through the detachable programming panel or a PC tool. The factory build includes no fieldbus option, leaving the communication bay available for PROFIBUS, DeviceNet, or other modules when required. This base configuration leaves network selection open for systems that need a specific communications module later. The power section follows the standard hardware layout used in the VLT 5000 line, which keeps cabinet integration consistent across similar units.
