EM618 Series Engineering Cabinet


•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;

StepsOperation   content
InstallationCheck   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   millWiring   as required
Check before power onConfirm   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 checkWhether   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 settingsIn   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 correctlyPlease   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 millCorrectly   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-identificationBefore   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 parametersGeneral   parametersAccording   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 ControlSet   V/F curve, torque boost, slip compensation, AVR function and other parameters   according to load requirements
Vector controlSet   regulator parameters and torque control and setting parameters according to   load conditions.
No-load test run inspectionThe   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 inspectionAfter   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 OperationBasic   operationThe   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 operationSpeed   controlProgram   runningSet   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 RunningUsers   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 controlThe   output torque of the motor can be controlled according to the input torque   command value
Performance settingsSpeed   trackingWhen   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 decelerationIt   is mostly used in drag systems with relatively large inertia and occasions   sensitive to acceleration to reduce mechanical shock and avoid system   oscillation.
DC brakingBefore   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 controlProvide   multiple programmable input and output ports, which can be used in   combination with external controllers to solve various applications
