Control mode

The core feature of the Siemens 6SE70 inverter is the use of advanced full digital control technology and IGBT voltage source pulse width modulation (PWM) technology, which ensures efficient operation and high-precision control of the equipment. This inverter has two main control modes: vector control and motion control.

Vector control

Vector control can provide precise torque control and fast dynamic response, suitable for applications with high precision requirements, such as motor positioning and servo control.

Motion control

Encoderless vector control is suitable for simple applications such as fans and water pumps, and controls the motor speed by adjusting the U/f ratio.

Application scenarios

6SE70 inverters are widely used in various industrial automation fields, such as metallurgy, chemical industry, electric power and building materials, providing users with high-performance and high-reliability drive solutions.

Vector control (VC): Achieve highly accurate torque control and dynamic response, suitable for applications requiring precision control, such as equipment with encoders.

Motion control (MC): Vector control for servo systems, which can support advanced process functions and is suitable for occasions with strict requirements on dynamic performance.

Full digital control technology: Combined with advanced IGBT voltage source PWM technology, it provides high-speed, high-precision and high-reliability AC variable frequency transmission.

Structural composition

The hardware of the 6SE70 inverter includes the main control board (CUVC board), power board and DP communication board, with rich I/O interfaces and communication functions. This modular design not only improves the flexibility of the equipment, but also facilitates maintenance and upgrades.

Energy-saving effect

Siemens 6SE70 inverter can effectively control the speed and output power of the motor, realize load regulation, and thus achieve energy-saving effect. Compared with the traditional resistance or reducer speed regulation method, it can save energy.

Stable and reliable

With high-performance motor control and protection functions, it can monitor the working status and load conditions of the motor in real time, and automatically adjust the output power to ensure the stability and reliability of the motor operation. In addition, it also has multiple safety protection functions such as overload protection, overheating protection, and short circuit protection, which effectively extend the service life of the equipment.

Control function

Adopting digital control technology, it can realize speed regulation and position control. Through current and voltage control, it can realize smooth start and fast stop of the motor, improve production efficiency and product quality.

Versatility

Supports multiple working modes and control methods, and can adapt to different working environments and needs. Parameters can be set and adjusted through programming software to realize the switching and combination of multiple functions to meet the requirements of different application fields.

Convenient maintenance

With a friendly human-machine interface and simple operation method, it can intuitively display the working status and fault information of the equipment. It also supports remote monitoring and diagnosis functions, and can obtain equipment operation data and fault information in real time through the network, facilitating timely repair and maintenance.
