Method of controlling DC speed motor with frequency converter

The frequency converter is a device that can change the power supply frequency of the motor. By controlling the frequency and voltage output by the frequency converter, the speed regulation and control of the DC speed-adjustable motor can be achieved. The specific control methods are as follows:

1.Set the parameters of the inverter

First, the parameters of the inverter need to be set, including power supply voltage, power, motor type, etc. Set according to the rated current and rated voltage of the DC motor, and ensure that the output voltage range of the inverter is within the tolerance range of the motor.

2. Wiring

Wire the output port of the frequency converter and the input port of the DC motor. Generally, a ground wire, a three-phase power wire and an output wire are required. When wiring, you need to pay attention to protecting the equipment to avoid accidents such as short circuits.

3.Control parameter settings

Set the control parameters of the frequency converter according to actual needs, including speed setting, acceleration and deceleration time, etc. By controlling the frequency converter output frequency and voltage, the speed regulation and control of the DC speed-adjustable motor can be achieved.

4. Debugging

Before actual control, the frequency converter needs to be debugged and tested. By adjusting the output frequency and voltage of the frequency converter, the speed changes of the DC motor can be observed, and the control parameters can be gradually adjusted to achieve the optimal control effect.

Safesav SN300 series satisfies high performance requirements by using a unique control method toachieve high torque, high accuracy and wide speed-adjusting range. Its anti-tripping function andcapabilities of adapting severe power network, temperature, humidity, and dusty environmentexceeds those of similar products made by other companies, which improves the productsreliability noticeably
