Variable Frequency Drive MV810G1-4T2.2B – 2.2 kW, Three-Phase 380 V

Ventilation that follows the workshop's activity

In a machine shop or welding workshop, ventilation demand changes throughout the day. The MV810G1-4T2.2B adapts fan speed to the actual activity. Speed can be set manually, switched between preset steps through the digital inputs, or adjusted automatically from an air quality sensor signal. Soft starting eliminates current peaks and reduces stress on bearings and ductwork.

Control and monitoring

The drive uses high-performance vector control, with stable torque even at reduced speed. Setup and monitoring are done from the front panel (5-digit LED display) or from a laptop through the USB Type-C port.

Full connectivity

• 8 digital inputs, NPN/PNP selectable, including an HDI pulse input
• 2 analog inputs: 0–10 V and −10…+10 V / 0–20 mA
• Analog output, open-collector output, programmable relay for fault or run signal
• RS485 Modbus for connection to a PLC or BMS
• Optional cards: PROFINET, EtherCAT, CANopen, Modbus TCP, EtherNet/IP
• Optional PG card for encoder feedback

Applications: extract fans for workshops and small industrial buildings, medium-pressure centrifugal fans, box fans, water pumps, machine tools and conveyors.

FAQ

Will the motor overheat if it runs at low speed for long periods?
The motor's own fan cools less effectively at reduced speed. For long operation below about 50% speed, connect the motor thermistor to the drive's dedicated input.

Can I install the drive in a hazardous area (e.g. a paint shop)?
No. The drive is installed in a cabinet outside the Ex zone. The explosion-proof motor must be certified for operation with a frequency inverter.

Can I switch between 3 fixed speeds?
Yes. Preset speeds are selected through the multifunction digital inputs.
