Product Description

Engineering Cabinet Variable Frequency Inverter Drives Dedicated Engineering Cabinet VFD

•Stable operation with low frequency and high torque: 0.5Hz/150% rated torque is output smoothly, ensuring smooth and trouble-free startup of the ball mill;
•The convenient man-machine operation interface (touch screen) can conveniently set the multi-segment running time and the running frequency of each time period, and can conveniently check the current and voltage operation information through the man-machine interface;
•Excellent current limiting ability: ensure that the control cabinet does not trip when the load fluctuates frequently;
•Wide voltage input range, automatic voltage stabilization: to ensure that when the grid voltage drops, the output can still meet the torque output requirements of the lifting equipment;
•Wide range of speed adjustment: meet the requirements of light-load high-speed and heavy-load low-speed lifting equipment, and improve the working efficiency of the equipment;
•The Modubus communication interface is used to check the working status of the inverter;
•Instantaneous power failure non-stop function, can automatically feed back electric energy to ensure a certain torque output;
•The frequency converter and the motor are adapted to use with the same power, and there is no need to enlarge the capacity of the frequency converter;

Product Description

Product Parameters

Steps					Operation content
Installation					Check the power of the special frequency conversion control cabinet for the ball mill, and install the special frequency conversion control cabinet for the ball mill as required.
Wiring of special frequency conversion control cabinet for ball mill					Wiring as required
Check before power on					Confirm that the input power supply is correct, the input power supply circuit has been connected to the circuit breaker; the special frequency conversion control cabinet for ball mills has been grounded; the power cord is correctly connected to the R, S and T power input terminals of the special frequency conversion control cabinet for ball mills; the motor is correctly connected to the U terminal of the special frequency conversion control cabinet for ball mills. , V, W output terminals; the control circuit wiring is correct, the external switch is in the correct position; the motor is unloaded, and the mechanical load has been disengaged from the motor
Power-on check					Whether there is abnormal sound, peculiar smell, smoke, etc. in the dedicated frequency conversion control cabinet for ball mills; the power indicator light is on, the operation panel displays normal, and there is no fault alarm message; if there is any abnormality, please disconnect the power immediately for inspection
Parameter settings					In the case of the initial operation of the special frequency conversion control cabinet for ball mills, repairs, or replacement of motors, please restore the parameters to the factory values before performing subsequent operations
Enter the motor nameplate parameters correctly					Please enter the nameplate parameters of the driven motor correctly and check carefully, otherwise serious problems may occur during operation
Protection parameter setting of special frequency conversion control cabinet for motor and ball mill					Correctly set the limit parameters, protection parameters and protection methods of the special frequency conversion control cabinet and motor for ball mills, mainly including: maximum frequency, upper limit frequency, lower limit frequency, lower limit frequency running time, fault retry control, relay fault output, etc.
Motor parameter self-identification					Before selecting the vector control mode to run for the first time, the motor parameter self-identification needs to be carried out to obtain the accurate electrical parameters of the controlled motor. If the motor load cannot be disengaged, you can select the motor static self-identification; if the motor is still rotating, do not perform the motor parameter self-identification operation
Set control parameters			General parameters		According to the working conditions of the drive system, correctly set the direction of rotation, forward and reverse control, acceleration and deceleration time, drive mode, start and stop mode, input mode, etc.
			V/F Control		Set V/F curve, torque boost, slip compensation, AVR function and other parameters according to load requirements
			Vector control		Set regulator parameters and torque control and setting parameters according to load conditions.
No-load test run inspection					The motor is empty, use the keyboard or control terminals to start the special frequency conversion control cabinet for the ball mill to run, check and confirm the running status of the drive system; Motor: stable operation, normal rotation, correct steering, normal acceleration and deceleration process, no abnormal vibration and noise, no abnormal smell; Special frequency conversion control cabinet for ball mill: the operation panel displays normal data, the fan operates normally, the relay operates normally, no vibration, no peculiar smell. If there is any abnormal situation, immediately shut down and check the power
Load test run inspection					After the no-load inspection is normal, connect the drive system load Start the special frequency conversion control cabinet for the ball mill through the terminal or keyboard, gradually increase the load, and observe whether the system is running normally under the load; If there is any abnormal situation, immediately shut down and check
Normal Operation	Basic operation				The special frequency conversion control cabinet for the ball mill can perform normal start, run, stop, forward and reverse and other basic operating functions. If there is any abnormality, please check whether the input and start-stop function codes are set correctly
	Advanced operation	Speed control		Program running	Set the program to run the code. After setting, it can drive the system to run in a single cycle or repeatedly. If there is any exception, please check the program running code
				PID Running	Users can set the PID process control channel and PID regulator parameters according to the requirements of the drive system to realize the control of industrial processes.
		Torque control			The output torque of the motor can be controlled according to the input torque command value
	Performance settings	Speed tracking			When starting, the special frequency conversion control cabinet for the ball mill will automatically detect the current rotation of the motor, so as to smoothly cut into the operation and reduce the start-up impact
		S curve acceleration and deceleration			It is mostly used in drag systems with relatively large inertia and occasions sensitive to acceleration to reduce mechanical shock and avoid system oscillation.
		DC braking			Before starting or when stopping, direct current can be applied to the rotating motor to generate braking torque, so that the motor can stop rotating quickly
		Special terminal control			Provide multiple programmable input and output ports, which can be used in combination with external controllers to solve various applications
