Product Description:

The 175Z0036 belongs to the VLT 5000 Frequency Converters series manufactured by Danfoss. This variable-speed drive modulates the voltage and frequency delivered to an induction motor, allowing production equipment to match process demands without mechanical throttling. Within automated plants, it serves as the regulating element between the mains supply and the motor shaft, providing precise speed, torque, and energy management for conveyors, pumps, and fan systems.

The converter accepts a 380–500 V three-phase supply, providing direct compatibility with standard industrial distribution networks. A compact book-style IP20 housing allows the unit to fit into densely populated control cabinets while providing basic protection against accidental contact. In heavy-duty applications, the drive can sustain 1.1 kW of output when 110% torque is required, whereas short-term overload conditions up to 160% torque are handled at 0.75 kW. Conducted emissions are limited by an integrated Class A1 and Class B filter, permitting installation on power grids that enforce stringent electromagnetic compatibility limits without external line filters.

An internal process control card is installed, so the speed loop and proportional-integral functions run locally rather than relying on a PLC. The drive is extended with a 24 V backup and brake chopper; the backup maintains control logic during mains voltage dips, and the chopper dissipates regenerative energy during rapid deceleration. Operators interact through a supplied display module that shows set points, alarms, and operating hours directly on the front panel. The power electronics are assembled on non-coated circuit boards, which require enclosure conditions that protect the components from corrosive atmospheres. Because no fieldbus or application option is installed, configuration is performed through the keypad or hardwired I/O, making the drive suitable for standalone operation.
