ZFeng variable frequency drive Green Solution
Easy to implement automated control
Principle: The frequency converter has standard communication
interfaces and rich control functions, which can seamlessly connect
with automation equipment such as programmable logic controllers
(PLCs) and industrial computers, facilitating the automation
control of the production process. Through programming, remote
monitoring, fault diagnosis, and parameter setting of the motor can
be achieved.
Case: In an automated production line, a frequency converter is
used in conjunction with a PLC to automatically adjust the motor
speed and operating status according to production process
requirements, achieving automated control of the production
process. At the same time, through the communication interface of
the frequency converter, the operating parameters of the motor can
be transmitted in real time to the monitoring center, making it
convenient for management personnel to monitor and manage the
production process.
The starting process of the frequency converter is as follows:
When the frequency converter receives a high-level signal from the
RUN terminal, it will start running. For simple application
scenarios, a self-protection button switch can meet the
requirements. When the button is pressed, its internal self-locking
mechanism will keep the circuit closed, providing a continuous
high-level signal to the RUN terminal of the frequency converter,
thereby starting the frequency converter.
The starting of the frequency converter can achieve soft starting
of the motor, gradually increasing from low frequency and low
voltage, significantly reducing the starting current, minimizing
the impact on the power grid, and reducing the electrical stress on
the motor winding.
The frequency converter can provide a large starting torque during
startup, which is particularly advantageous for heavy-duty
starting, ensuring that the motor can start smoothly even under
heavy loads.
Starting the frequency converter can smoothly accelerate the motor,
reduce noise and vibration during the starting process, and improve
operational comfort.
