| 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 | ||||
