Operation of VMX series soft starter of hottest mo

The operation of VMX series of motor soft starter

the setting of ramp time, starting torque and ramp type shall meet the motor's operation under full load. The factory settings can meet the motor use and basic protection conditions of most users. If there are special requirements, it can be adjusted appropriately, and the adjustment is often operated by using the digital operation interface, that is, the commonly known "panel" or "operation keyboard"

(I) operation interface

vmx series soft starter control interface includes: 8 high brightness LED, 7 function setting keyboard, 4 seven segment nixie tube display modules. Its functions are listed in the table

Press the [fn] key to enter the programming mode. If you enter the programming mode for the first time, the number [f001] will flash after power on. If the VMX has been set and the power is turned on, the last viewed or changed function will be displayed. Use the arrow keys to change the display

(1) browse programmable functions and parameters

each programmable function can be viewed without changing (parameters can also be viewed without changing in the running state). Each function is preceded by the letter "F". Press the read/enter key to display the parameters

[f001] the letter "F" indicates function; [0000] represents the set value of the current function, and the display may have a decimal point due to the different range of function parameter settings and the minimum increase

note: if the password is set, the operator needs to set the parameters according to the password

(2) password protection/parameter locking

figure programming mode

vmx series can select password protection through [f070]. If parameters need to be protected, passwords can be set in [f070]. If pressing re is attractive, the ad/enter key displays [err] indicating that the parameter is locked

(3) change the parameter setting

when the read/enter key is pressed, the function parameters will be displayed, and a digit will flash (usually the rightmost digit). A flashing number indicates that the current number can be changed. Use the up and down direction keys to increase or decrease the value, and use the left and right keys to change the next value to be changed. The value can be adjusted within the adjustment range

when the parameter is changed to a predetermined value, press the read/enter key to save the parameter. The screen displays end and changes to function number

note: if the equipment is powered off before pressing the read/enter key, the parameters will not be saved

3. Fault display mode

fault display mode displays fault information, and users can also view fault records. The fault code is three letters, the first two are the English abbreviations of the fault, and the last one is a, C or D. "A" indicates the acceleration phase, "C" indicates the operation class, and "d" indicates the deceleration phase

as shown in the figure, please read the status display

check the fault record, [pla.] Indicates phase failure in acceleration phase, and decimal point indicates recent fault

press the up arrow, [ibc] indicates the phase to phase imbalance during operation

press the up arrow, [olc] indicates overload during operation

press the reset key, [rst] flashes once, indicating that the recent fault has been successfully reset. If it cannot be reset, it will display [inh]

[0000.] Return to the default display surface, indicating that the soft starter can be restarted

fault records are only generated when faults occur. You can use the up and down arrows to view the history records. You can check the failure time and date through f085 to f093

(1) fault reset

after troubleshooting, press the reset key, and the screen will return to the status display mode. Press the [reset] key on the panel to reset the fault. Most faults will reset automatically when the soft starter is powered on again. Unless there is enough time for the thermal overload relay to recover to the ability to restart, it cannot be started

(2) remote reset

most faults will reset automatically when the soft starter is powered on again. A dynamic breaking contact (or button) can be connected to the control circuit of A1 or A2 for remote reset

this function, such as the minimum time interval between two starts and the limit of starts per hour, is based on the internal real-time clock (RTC). When the soft starter is powered off, the RTC information is quickly saved, and the timer will automatically update according to the RTC. If the locking time is not up, the soft starter does not
