（2） Key Function Analysis

Encoder free control technology

Core principle: By utilizing the electrical salient pole characteristics of IPM motors, speed, steering, and rotor position can be detected without the need for a motor encoder, achieving high-precision positioning control.

Functional value: Reduce encoder hardware costs and installation complexity, lower failure points, and adapt to applications with limited space or harsh environments.

Supporting tools: Through DriveWorksEZ visual programming, it is easy to create custom position control sequences without the need for additional controllers.

Braking and Parking Technology

Built in braking capability: 30kW and below models come standard with a braking transistor, which can be directly connected to an external braking resistor to achieve strong braking; Models above 30kW can expand the braking unit through the tab.

Braking mode: Supports overexcitation deceleration (achieving quick stop without braking resistance), high slip braking (braking torque of about 40%), and DC injection braking (auxiliary braking during start/stop phases).

Power failure protection: KEB (Keep Energy Braking) function can use the regenerative energy of the motor to achieve controllable shutdown within 2 seconds after power failure, avoiding safety risks caused by free sliding of the load.

Self tuning and optimization functions

Motor self-tuning: supports rotation self-tuning (high-precision matching of motor parameters), static self-tuning (used when the motor cannot be disconnected from the load), and wire resistance self-tuning (recalibrated after cable length changes).

Load self-tuning: Inertial self-tuning optimizes deceleration performance, ASR gain self-tuning automatically matches frequency reference to ensure stable operation under different loads.

Energy saving self-tuning: Real time optimization of motor voltage and load matching, always maintaining the highest operating efficiency.

Energy saving control technology

Induction motor energy saving: dynamically adjust the output voltage through Energy Saving control, automatically optimize according to speed and load, and reduce no-load losses.

Energy saving synchronous motor: Paired with the EMR1 series ultra efficient synchronous motor, the efficiency is improved by 8.2% -13% compared to traditional induction motors, and the application effect of fans/pumps is particularly significant.

Harmonic suppression: Models of 22kW and above are equipped with built-in DC reactors, reducing the harmonic distortion rate of the power grid from 88% to 40% and minimizing interference with the power grid.
