Features and benefits:

• Integrated Class C2 EMC filter reduces external filtering requirements in most installations.
• Multiple asynchronous motor control profiles: sensorless flux vector (standard and energy saving), U/f 2-point, U/f 5-point, and quadratic U/f energy saving; sensorless vector control also available for synchronous motors.
• Built-in STO, SS1, and SLS safety functions enable compliant machine safety integration without additional safety relays.
• Integrated braking resistor with 4-quadrant operation supports dynamic braking to standstill via DC injection.
• Compact 140 x 184 x 158 mm, 2.1 kg format simplifies panel installation in space-constrained enclosures.

Applications:

• Variable speed control of three-phase induction and synchronous motors in complex industrial machines.
• Packaging lines, conveyors, and material handling equipment requiring precise speed and torque regulation.
• Pump and fan drives where energy-saving quadratic U/f control reduces power consumption.
• Safety-critical machinery requiring certified STO and SS1 functional safety compliance.
