Features and benefits:

• Multiple motor control modes - sensorless flux vector, U/f (2- and 5-point), and Energy Saving variants - for both asynchronous and synchronous motors
• Integrated braking resistor and DC injection braking enable controlled stopping without external braking hardware
• Built-in STO, SS1, and SLS functional safety reduces wiring and eliminates the need for additional external safety relays
• Four-quadrant operation with transient overtorque up to 200% of rated torque suits demanding machine cycles
• Integrated Class C2 EMC filter and optional fieldbus communication modules for Profinet, EtherCAT, and Ethernet/IP simplify panel design

Applications:

• Variable speed control of small three-phase motors on complex industrial and OEM machines
• Conveyor, pump, and fan systems requiring precise speed and torque regulation
• Compact automation panels where wall-mount installation and integrated fieldbus connectivity are required
• Safety-critical machinery where STO or SLS must be implemented without additional external components
