Product Description:
The 178B2094F refers to the Danfoss frequency converter. It has rated output power of 1.1 kW. This converter refers to FCD311PT4P66EBR1D0F10T00C0 product which ensures consistent performance. It is intended for motor-mounted or stand-alone mounting applications. It belongs to the VLT FCD 300 Micro Drives series.
The Danfoss 178B2094F provides reliable operation with a mains voltage input of 3 × 380-480 V AC at 50/60 Hz. It has a rated output power of 1.1 kW, or 1.5 HP, and a maximum constant output current of 3.0 A, with a maximum constant output power of 2.0 kVA at 400 volts. The drive can support motor frequencies ranging from 0.2 to 132 Hz, with an extended frequency of up to 1000 Hz. It operates on the Voltage Vector Control switching principle, with continuous monitoring. The built-in DC coils improve power factor and lower harmonics. It incorporates built-in protection against overcurrent, short circuit, and ground fault. The unit also includes superior electronic thermal protection and adjustable ETR functionalities. For indoor use, the enclosure protection rating is IP66 or NEMA 4X. The cooling clearance required is 100 mm above and below the drive. The optional LCP2 control panel features a four-line alphanumeric display that includes status, alert, warning and ON indicators. Control keys provide local operation with Start, Stop, Reset, Forward, Reverse and JOG functions. The system supports programmable digital and analogue inputs or outputs and is PELV compatible. The standard RS485 interface supports the FC, Profidrive, Profibus DP, and AS-i protocols. Brake options include an internal brake resistor for short-duty use and an external resistor for high-torque braking. Dynamic braking is possible down to 8% of the rated speed. AC braking allows up to 50% torque braking.
The 178B2094F frequency converter provides reliable performance in harsh conditions. Operating temperature allows derating above 45 °C with altitude derating above 1000 m. The IP66 enclosure resists wash-down cleaning in food and beverage environments. Compliance is ensured with CE, UL, and EMC directives. The built-in RFI filter ensures EMC compliant installation. The converter ensures robust efficiency in industrial environments.
Frequently Asked Questions about 178B2094:
Q: How does the Voltage Vector Control improve motor performance in the 178B2094F Decentralized Frequency Converter?
A: The Voltage Vector Control ensures precise torque and speed regulation. It helps reduce motor losses and improves stability during variable load conditions.
Q: Why is the external brake resistor recommended for the 178B2094F Decentralized Frequency Converter?
A: The external resistor supports high-torque or continuous braking cycles. It prevents overheating and maintains system safety during frequent stops.
Q: What role do programmable I/O functions play in this drive?
A: They allow users to configure inputs and outputs for application needs. This flexibility reduces wiring complexity and improves system integration.
Q: How does altitude derating affect the 178B2094F Decentralized Frequency Converter?
A: At elevations above 1000 m, air density decreases. This limits cooling efficiency, requiring derating to protect internal components.
Q: How does the built-in RFI filter in 178B2094 drive impact EMC compliance?
A: The filter reduces conducted emissions back into the mains. It ensures compliance with EN 55011 standards for industrial environments.
