Reynolds drives RNB1000 series fault code resolution

The acceleration time of the Reynolds inverter is the time required for the output frequency to rise from 0 to the high frequency, and the deceleration time is the time required to decrease from the high frequency to 0. Generally, the frequency converter uses the frequency setting signal to rise and fall to confirm the acceleration and deceleration time. The rise of the frequency setting must be limited when the motor accelerates.

1. If the bearing is in good continuous rotation condition, it will emit a low whining or humming sound. Sharp hissing, squeaking and other irregular sounds often indicate that the bearing is in a bad continuous rotation condition. The sharp squeaky noise can be due to the formation of an inappropriately smooth ...

When the differential pressure flowmeter (V-cone flowmeter) is used in the field, it often encounters such and such problems, but the reason for it is investigated, as long as it is installed correctly, the primary problem is on the secondary surface differential pressure transmitter, and the following is the first to introduce these problems to us ...

1. Overpressure leads to brake pipe breakdown. The so-called overvoltage of the inverter refers to the fact that the inverter voltage composed of various reasons exceeds the additional voltage, which is reflected in the DC voltage of the inverter DC bus. Overvoltage alarm generally appears when the machine is shut down, and its main ...

1. The acceleration moment is too short. Theoretically, the longer the acceleration time, the stronger the load lifting capacity. If the acceleration time is set too short, some VFDs will show an overcurrent or overload, overtemperature alarm, while others will not, and will only be stuck in a certain frequency band. 2.The V/F ratio is too large Some of this ...

Voltage level: The voltage level should match the voltage level of the power supply and motor to ensure electrical safety and normal operation of the equipment. Current level: The current level should match the rated current of the motor to ensure electrical safety and normal operation of the equipment. Cable Specification: Cable ...

a. Output frequency scale. The output frequency scale that can be controlled by the general inverter, the lowest starting frequency is generally 0.1Hz, and the highest frequency is different according to the functional indicators of the inverter, generally 400Hz, and some models are 650Hz. No matter how high the output frequency is, it depends on the scale of the high-frequency inverter. ...

The fundamental principle of vector control is to control the excitation current and torque current of the asynchronous motor according to the principle of magnetic field orientation through the measurement and control of the stator current vector of the asynchronous motor, and then to achieve the purpose of controlling the torque of the asynchronous motor. Specifically, it is to ...

1. The cause of the leakage problem Some sites use frequency converters to control the motor, which will present the problem of leakage, and the leakage voltage ranges from tens of volts to 200 volts. In view of this problem, the reasons for this shortcoming are theoretically expounded and stated as follows. Depend on...

Undervoltage is also a problem that we often encounter in application. Mainly because the voltage of the main circuit is too low (220V series is lower than 200V, 380V series is lower than 400V), the main reason: a certain way of the rectifier bridge is damaged or there is abnormal operation in the three ways of the thyristor, which may lead to the appearance of undervoltage problems, ...

Because inverters are widely used, there are many differences in the corresponding types and specifications. We are broadly divided into two categories: voltage and current. The current type of inverter products is characterized by the use of a large inductor as the energy storage link in the middle DC link, and the reactive power will be buffered by this inductor. ...

1. In order to save power, the inverter is selected Many manufacturers and salesmen praise how high the power-saving rate of the inverter is, and the user also believes that it is true, and the inverter is selected at a high cost simply in order to save electricity, but the results are greatly disappointed. Whether the inverter can save power after using it is determined by the load driven by it.

1. The inverter itself has a strong electromagnetic disturbance, which will disturb the work of some equipment, so we can add a cable sleeve to the output cable of the inverter. 2. The control line in the inverter or control cabinet is at least 100mm away from the power cable, etc. ...

Each type of servo motor has additional torque, maximum torque and servo motor inertia and other parameters in the standard items, each parameter and load torque and load inertia must have a relevant connection, the output torque of the servo motor should meet the requirements of the movement conditions of the load organization, such as the speed of the acceleration ...

International electrical safety standards: The requirements are in line with international electrical safety standards, such as CE standards in Europe and UL specifications in United States. These specifications specify the requirements for electrical safety functions, mechanical safety functions, EMC functions, etc. ...

The first step is to check whether the appearance of the inverter is defective, including whether the indicator light is in normal operation, whether the mission control function of the operation panel is complete, and carefully observe the appearance of the inverter under the operating condition, and do the corresponding recording operation; When repairing the inverter, check whether the voltage value and current value exceed the ...

Causes of inverter failure: 1. The grid voltage is too low 2. The rated current of the motor is set incorrectly 3. The motor stall or load abrupt change is too large 4. Large horse-drawn trolley Inverter solutions: 1 ...
