1. Select varieties according to the above series according to the purpose and requirements of use Note that the main circuit load type is strictly differentiated, whether it is DC or communication. The communication contactor is different from the DC contactor, and is only suitable for DC-1 to DC-5 loads when used for DC loads.

1. Direct launch The universal inverter insists on starting at the beginning of the time according to the set starting frequency and starting frequency, and then accelerates to a given frequency according to the selected acceleration time Second, the speed of the tracking start Universal inverter ...

Compared with the motor driven by the inverter, the power factor and efficiency of the motor will deteriorate and the temperature rise will increase because the output waveform of the inverter contains the influence of higher harmonics. On the other hand, when the frequency conversion is driven, the same torque should be obtained as when the power frequency power supply is driven, ...

The high-voltage inverter has been designed with the safety of the user in mind. However, due to the energy storage capacitor installed inside the power unit of the inverter, it may still carry a high voltage after disconnecting the power supply, and some parts generate a lot of heat, so contact is prohibited. When working on or near the inverter, please ...

Common troubleshooting methods for Reynolds soft starters. 　　During the debugging process of the soft starter, the fault light is on, the motor is unresponsive, and the cause of the fault is analyzed: When the starting mode adopts the live mode, the operation sequence is wrong (the correct operation sequence must first deliver the main power supply, and then the control ...

1) Query and query fault phenomena. The fault phenomenon of the inverter is varied, for example, the same type of problem may have different problem phenomena, and different types of problems may have the same kind of problem, which brings difficulties to find the problem. However, the problem phenomenon is the fundamental basis for repairing the inverter ...

Installing a variable-frequency drive (VFD) on the power frequency motor can complete the precise control and speed regulation of the motor, and improve the power and accuracy of the progressive motor. However, if it is not properly used and used, the following damages may occur: ...

According to the different degrees of short circuit, the inverter can display the short circuit of the SCF1 motor; SCF2 has an impedance short circuit; SCF3 is short-circuited to ground. Causes of the problem: insulation problems with the cable from the motor or inverter to the motor; current transformer fault; ...

JJR8000 series of intelligent motor soft starter is the use of power electronics skills, microprocessor skills and modern control theory skills to produce today's international first-class starting equipment, the product can constrain the starting voltage of the asynchronous motor when starting, can be used in fans, water...

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% ...

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 ...

1. See if it is energy-saving. When selecting equipment products, many business managers will take into account the energy-saving embodiment, which is due to the excellent energy-saving embodiment of the product, which can save a lot of money and resources.

That is, the upper and lower amplitudes of the output frequency of the inverter. Frequency is a maintenance function to avoid misoperation or failure of the external frequency setting signal source, which causes the output frequency to be too high or too low, so as to prevent damage to the equipment. You can set it according to the actual situation in the app. This function can also be used as a speed limit, so that ...

1. Energy consumption braking: The energy consumption braking method uses the braking resistance set in the DC circuit to absorb the regenerative electric energy of the motor through the chopper and braking resistor, so as to realize the rapid braking of the inverter. 2. Feedback braking: feedback system ...

The motor itself: 1) The inner and outer rings of the bearing are too tightly cooperated. 2) There are problems with the shape and position tolerance of parts, such as the coaxiality of parts such as machine base, end cover, shaft and other parts is not good. 3) Improper selection of bearings. 4) The bearing is not smooth or the bearing is not clean, and there are impurities in the smooth grease. ...

1. FUN button; Press the FUN button to enter the settings menu F00; 2. Press and hold the up button or down button to scroll to the code that needs to be set; 3. Press the FUN button to confirm at this moment, and adjust the entry parameters to the required value; 4. After the adjustment is completed, press the WR storage button, and then the panel will display the ...

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 drop from the high frequency to 0. Usually, the inverter uses the frequency setting signal to rise and fall to confirm the acceleration and deceleration time. When the motor accelerates, the rise of the frequency setting must be constrained ...

Take the RNB2000 series inverter as an example. The model number of the RNB2000 series 37kW inverter is: RNB2037-U RN: on behalf of Reynolds; B: low-voltage frequency conversion governor; 2: 2000 series; ...

Overload can be different Servo drives generally have 3 times the overload ability, which can be used to overcome the inertial moment of the inertial load at the moment of start-up, while the frequency converter generally allows 1.5 times the overload. Handling precision Servo control ...
