Advanced vector control technology: The advanced vector control technology of Siemens 6SE7018-0EA61 can realize the precise control of the motor. The magnetic flux and torque of the motor are decoupled, respectively, so that the motor can still have good performance at different loads and speeds, and have rapid dynamic response and high speed regulation accuracy. It can be used for example in the spindle drive for machine tools that require high-precision speed control to ensure that the spindle runs at a stable speed to meet the precision requirements of the processing technology.

Multi-speed and PID control: Built-in 7-segment fixed frequency switching, support external analog/PID closed-loop control (such as constant pressure water supply, temperature regulation).

Integrated brake unit: Siemens 6SE7018-0EA61 has a built-in brake chopper, support external brake resistor, achieve rapid energy discharge, and the deceleration time is shorten by 40% compared with APP ordinary frequency converter.

Machine tool industry: Siemens 6SE7018-0EA61 can be applied to machine tool spindle drive and feed axis drive. The spindle drive can verify spindle speed and torque according to processing technology demand, so as to achieve high-speed cutting and precision processing; the feed shaft drive can enable accurate motion of workbench and tool to improve processing accuracy and surface quality.

Textile industry: In textile machinery like spinning machines, looms, etc, it is used to control the speed and tension of the motor. The uniformity of yarn and the quality of the fabric are ensured by the precise speed control; the tension control function is used to hold the yarn in the processing course stable. 

Elevator industry: Siemens 6SE7018-0EA61 is the drive device of the elevator, which can realize smooth operation and accurate parking of the elevator. The vector control technology can carry out automatic adjustment of the output torque and speed according to the load of the elevator, so that the elevator can maintain good performance in the start, operation and stop process, and ensure the comfort and safety of riding.

Fan and pump applications: For fan and pump equipment, the motor speed can sparingly be adjusted according to the actual flow and pressure requirements for energy-saving operation. When the load of the system is small, the speed of the motor is lowered to save energy; when the load changes, Siemens 6SE7018-0EA61 can respond quickly, which can ensure that the system works stability.
