Functional features:
1. The varispeed G7 frequency converter has successfully greatly reduced the adverse effects on the motor and power supply. Solve the potential problems of the frequency converter while improving the level of mechanical equipment.
2. Use high-performance and multi-functional varispeed G7 to fully meet the high technical requirements of users. It has user-specific functions and rich software memory, which can quickly respond to users' special requirements. From parameter setting to maintenance, the user pursues ease of use.
3. For the first time in the world, the 3-level control method is applied to the 400V universal frequency converter, so that the output voltage of the frequency converter is closer to the sine wave. It completely solves the problem of motor insulation damage caused by impulse voltage and electrical corrosion of motor spindle caused by shaft voltage. Therefore, even without a surge suppression filter, the variable frequency drive can be used with confidence through motors and existing motors. Significantly reduces leakage current noise. (Half less than the original)
Specialization of frequency converters
通过用户专用型功能，在变频器内部记忆区域内置用户机械所需要的特殊功能（专用软件），为客户提供专用变频器
Crane control, elevator control, energy-saving control (motor maximum efficiency operation), PID control, etc
LCD display with 5 lines shows the operator, and if an extension cable is used (optional), the operator can be operated away from the machine for long-distance operation
Easy to replace components, equipped with a computer inverter service tool, can manage the parameters of each inverter in one place to ensure reduced maintenance work

High level of control performance
1. Outstanding torque characteristics: The torque characteristics in the low-speed area are further improved (150%/3Hz without PG vector 2 control) to achieve strong power for all machinery. If PG is installed, it can operate from zero speed to high torque of more than 150%.
2. Outstanding responsiveness: Equipped with model tracking control, it can achieve high-speed response (more than 2 times faster than our original product) even without PG, and with PG control, it can quickly track changes in speed instructions (speed response 40Hz/motor unit) even if it relies on the original high-speed current vector control, and can also maintain a constant speed for sudden changes in load.
3. Simple self-learning mode: On the basis of the existing rotational self-learning mode, a new "stop self-learning mode" has been added. Self-learning made easy to maximize the efficiency of your motor. Precise Torque Limiting: A precise torque limiting feature that precisely limits the output torque. Machinery is also protected in the event of sudden load imbalances
4. Fast speed search (patent): Using the new speed search function, the first officer shortens the re-start time after stopping and returning (less than half of the company's original product), and realizes re-operation regardless of the direction of rotation
