A frequency converter is a device that converts industrial frequency power sources (50Hz or 60Hz) into AC power sources of various frequencies. Siemens frequency converters are used for maintenance to achieve variable speed operation of motors. The control circuit completes the control of the main circuit, the rectification circuit converts AC power into DC power, the DC intermediate circuit smooths and filters the output of the rectification dgjrie4366 circuit, and the inverter circuit converts DC power back into AC power. For inverters such as vector controlled inverters that require large calculations, sometimes a CPU for torque calculation and some corresponding circuits are also required. Siemens frequency converter maintenance variable frequency speed regulation is achieved by changing the frequency of power supply to the stator winding of the motor to achieve speed regulation

Motor and frequency converter protection
On the basis of PID control (motor grading), * can control up to 3 additional drives
Connect to the main power supply (with external bypass circuit) to run the drive
Low energy interior mode
Check the dry running status of the pump (belt fault detection)
Advantages of variable frequency speed regulation in motor operation
1) Variable frequency speed regulation is easy to achieve forward and reverse rotation of the motor. Simply changing the switching sequence of the inverter tube inside the frequency converter can achieve output commutation, and there is no problem of burning the motor due to improper commutation.
2) The start-up of variable frequency speed control systems mostly starts at low speeds and has a lower frequency. The acceleration and deceleration time can be set arbitrarily, so the acceleration and deceleration time is relatively gentle, the starting current is small, and higher frequency start and stop can be carried out.
3) When the variable frequency speed control system brakes, the frequency converter can use its own braking circuit to consume the energy of the mechanical load on the braking resistor, and can also feed back to the power supply grid. However, adding accessories to feed back to the power grid requires significant investment. In addition, the frequency converter also has a DC braking function. When braking is required, the frequency converter adds a DC voltage to the motor for braking, so there is no need to add another braking control circuit.
4) A frequency converter can replace a DC engine, and an induction motor is used at this time. Similar to DC engines, it does not require brushes, slip rings, etc., and has maintenance and environmental resistance.
5) Control several engines in parallel with one frequency converter
6) The frequency converter can be soft started and soft shut down, and the acceleration/deceleration time of the engine can be adjusted arbitrarily.
7) Reduce the starting current. Through the soft start and soft shutdown of the frequency converter, the starting current can be reduced to 1.5-2 times the rated current of the motor when starting. When starting directly, a starting current of 6 times the rated current flows, therefore
It will bring load to the frequent operation/stop of the motor.
8) The rebound braking of the frequency converter facilitates electric braking.
