Features and benefits:

• Sensorless vector control enables accurate speed regulation without a motor encoder
• Integrated Class A EMC filter removes the need for an external filter in most installations
• Fail-safe digital input supports safety-related control functions directly at the drive
• USS/MODBUS RTU communication allows integration into standard automation networks
• IE2 efficiency class and 0.97 efficiency rating reduce energy losses in continuous-duty applications

Applications:

• Variable-speed control of three-phase induction motors in industrial machinery
• Pump and fan systems where V/f ECO control mode delivers energy savings
• Conveyor and handling equipment requiring high overload capability (200% for 3 s in HO mode)
• Control panel installations where the compact FSAA frame and built-in Class A filter save space and cost
• Networked automation systems communicating via MODBUS RTU or USS protocol
