[RS485 Interface] The converter provides a RS485 communication interface, and uses standard communication protocol. Users can read and write parameters, control commands, etc. [Brake Unit] The inverter has built in brake unit, which can be connected with an external brake resistor for emergency stop braking. [Easy to Use] The frequency converter adopts humanized keyboard design, digital display, easy to operate, simple and clear. [Cooling Fan] The heavy duty inverter has a built in cooling fan, which improves the stability of the machine, reduces the noise and improves the service life.[Excellent Component] The VFD inverter adopts original chip, excellent capacitor, the circuit board uses special protective paint, which is dust, dirt and alkali resistant, making the performance more stable. Item Type: Variable Frequency Drive Material: Flame Retardant ABS Power: 22KW Applicable Motor Power: 22KW Input: AC 3PH 380V 5060Hz 50A Output: AC 3PH 380V 0-300Hz 45A.
1 x Variable Frequency Drive. Before wiring, please confirm whether the input power supply is powered off.
The wiring operation shall be carried out by professional electrical engineering personnel. The grounding terminal must be grounded. After the emergency stop circuit wiring is completed, be sure to check whether the action is effective. The output line of the frequency converter must not be connected with the housing, and the output line must not be short circuited.
Please confirm whether the voltage of AC main circuit power supply is consistent with the rated voltage of frequency converter. Do not carry out voltage withstand test on the frequency converter. Please connect the braking resistor according to the wiring diagram. Do not connect the power cord to the output U, V, W terminals.
Do not connect the contactor to the output circuit. Be sure to install the protective cover before powering on. When removing the cover, be sure to disconnect the power supply.Select the frequency converter with reset and retry function, and keep away from mechanical equipment. Because the alarm will suddenly restart when it stops. The alarm can be reset only after confirming that the operation signal is cut off. When the alarm is reset under the operation signal state, the converter may start suddenly.
Do not touch the terminals of the converter. There is high voltage on the terminals, which is very dangerous. Do not change wiring and terminal disassembly during power on. Cut off the power supply of the main circuit before inspection and maintenance. Do not modify the frequency converter without authorization.
