Siemens inverter 6SE6440 MICROMASTER VFD
The domain of drives is forever influenced by forces that are difficult to control. It would hence take the most powerful of frequency inverters to meet the diverse challenges simultaneously. The MICRO- MASTER 440 has been specially designed for those applications which require broader functionality and a greater dynamic response than is usually the case. The sophisticated vector control system ensures a uniformly high drive quality, even when sudden load changes occur. Fast response inputs and positioning deceleration ramps allow movement to target positions even without an encoder. Due to an integrated brake chopper, it works with outstanding precision, even during braking and short declaration ramps. All this is possible within a power range starting at 0.12 kW (0.16 HP) and going up to 250 kW (350 HP).
Typical uses
Numerous applications in areas such as material handling systems, the textile industry, elevators, hoisting gear, mechanical engineering and the food, beverages and tobacco industries.
Strengths
- Compact housing
- Easy to install
- Sophisticated vector control (speed/ torque)
- Versatile inputs and outputs
- Guided commissioning
- High overload capacity
- Evaluation of motor pulse encoders (optional)
- Modular system of extension options
- Can be dimensioned for CT (con- stant torque) or VT (quadratic, i. e. variable torque)
- 3 selectable drive data
- Load torque monitoring
- Kinetic buffering against voltage dips
- Compound braking for controlled rapid braking
- Integrated brake chopper for power outputs up to 90 kW (125 HP)
- Free function blocks
- 4 skip frequencies
- Automatic restart
- Designed to Minimize stress on motor when connected to rotating motor
- Evaluation of motor temperature
- Customized for IT Networks
- Available with and without integrated EMC filter
