Various ways to meet different needs

Various ways to meet different needs

1. V/F control: It is used for all variable speed controls that do not require fast response and high-precision speed control, and where multiple motors are connected with one inverter.
2. No PG vector control: used for all variable speed control, especially when high-precision speed control is required, the torque response is fast and the motor can also obtain a larger torque when running at low speed.

Reliable strength, provide control strategy

1. It has two self-learning methods of static/rotating to obtain accurate electrical parameters of the motor.
2. Under light load, one inverter can start with multiple motors to track and start, optimize the tracking function of software and hardware, and the accuracy of speed tracking is higher.
3. Effectively reduce the noise of the motor and suppress the interference of the inverter to external equipment.
4. There is no need to add peripheral braking resistors and other accessories to achieve a rapid braking effect, which can effectively suppress the rise of bus voltage during deceleration and avoid frequent overvoltage faults.

Rich functions, covering industry applications

1. The new generation of energy-saving operation can realize the operation of the induction motor, and calculate the output voltage according to the load to achieve the purpose of energy-saving. It is mostly used on the occasion of energy-saving transformation.
2. The standard swing frequency is suitable for occasions where the swing frequency control is required for textiles and chemical fibers. The swing frequency amplitude, speed, and frequency can be set freely.
3. A variety of PID control, divided into ordinary PID and pressure closed-loop dedicated PID, wider application scope, and stronger industry pertinence.
