The cause of overheating of servo motor bearings - Reynolds

Low pressure issues The VFD reports a low voltage issue when the drive's DC link voltage drops below 62% of the nominal level at the high setting (480 Vac) and 50% of the nominal value at the low setting (400 Vac). The +10% and -15% voltage tolerances in most manuals are the ones that claim to be ...

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. After 200-300 hours of operation, the first oil change should be carried out, and the quality of the oil should be checked regularly in the subsequent use, and the oil mixed with impurities or deteriorated oil must be replaced in time. Under normal circumstances, the reducer for long-term continuous operation should be replaced after 5000 hours of operation or once a year.

The fulfillment device commonly used in the industrial field of Reynolds inverter has good speed regulation performance and simple and convenient operation method.

In order to measure stable harmonics, it is necessary to meet the following two conditions: At the top of the list, the signal is a stable periodic signal. Second, it is necessary to perform harmonic analysis according to the integer multiple of the period of the stable periodic signal. ...

Energy storage elements are different, the voltage type energy storage element is a capacitor, and the current type is an inductor. In fact, the general inverter uses power electronic circuits, which is a process of communication to DC - DC energy storage - DC to communication. It is also often said that the rectifier link --〉 energy storage link --〉 inverter ring ...

A frequency converter is a power electronic device that can change the frequency of an AC power source to control the speed and output power of a motor. Inverters are widely used in industry, aviation, metallurgy, petroleum, chemical industry, electric power and other fields.

1. The output of the inverter for overvoltage maintenance has the function of voltage detection, and the inverter can actively adjust the output voltage, so that the motor does not bear the overvoltage, and the motor runs within the set voltage range. 2. Undervoltage maintenanceWhen the voltage of the motor is lower than 90% of the normal voltage (some are set to 85% ...

The output of the inverter is controlled by PWM (pulse width modulation, similar to high-speed switching), so a high frequency leakage current will occur, if you want to install a general leakage disconnect switch on the primary side of the inverter, it is recommended to select a sensitivity current of more than 200mA for each inverter and the action time is 0.1 seconds ...

The inverter is composed of many electronic parts, such as semiconductor components, etc., in the application and protection involves the replacement of a related component, because of the composition or physical characteristics of the inverter, it will deteriorate in a certain period of time, which will reduce the characteristics of the inverter, and even ...

(1) Inverter three-phase communication input terminal (R, S, T) The power input terminal is connected to the three-phase communication power supply through the circuit breaker of the circuit breaker for line protection, regardless of the connection phase sequence. It should be noted here that the three-phase communication power supply must not be directly connected to the inverter output ...

Soft Starter Repair Problem: F 04 (Input Phase Loss): There are several factors that cause this problem, some of which are listed below: (1) Check whether the wiring between the incoming power supply and the motor is loose; (2) Whether the output is connected to the load, and whether the load is matched with the motor; (3) ...

According to the requirements of the operating conditions, the appropriate load inertia accounting formula is selected to calculate the load inertia of the organization. According to the load inertia and servo motor inertia, the appropriate servo motor standard is selected. Combined with the inertia and load inertia of the primary servo motor, the acceleration torque and deceleration are calculated.

1. What are the factory parameters of inverter rehabilitation? N600 = 100 (often press the WR button for 3-5 seconds), it is necessary to be in the shutdown state to be effective. 2. In the parameters of the N308 motor of the inverter, [motor leakage inductance reactance] is the specified sub...

Recently, in the "2012 National Torch Program Project" issued by the Ministry of Science and Technology of the People's Republic of China, the "RNB6000 Frequency Conversion Governor" independently developed by Reynolds was included in the "2012 National Torch Program Project" with its domestic leading skills and efficient energy-saving conversion power.

In the process of daily use of soft starters, it is inevitable to encounter some improper use or failure of soft starters in the process of use 1. The user starts ...

Inverters are widely used in all walks of life, in a variety of applications, inverters will inevitably encounter rainy and humid climate, resulting in internal wetness, or accidentally into the water, in fact, as long as it is found in time, it can still be rescued. If it is in the unpowered state ...

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 ...
