\r\n\t\t\t\tBefore connecting my S100 device to the motor on the production line, I gave electricity. Output voltage drops during acceleration when testing the inverter without a motor. I need to test whether the inverter is working before using it on the production line. <\/i><\/i><\/span>\r\n\t\t\t\t
\r\n\t\t\t\t\t

The problem is that the output terminal (motor) is not connected to the inverter. This is a normal result as software is programmed this way for security measures. The problem can be fixed by connecting the motor to the inverter. But the same situation can be encountered when the motor is connected. The safety program is activated according to the amount of output current produced from the inverter. The output voltage may drop if the motor capacity is small compared to the inverter causing very small output current. If this program makes it difficult to use and there are requests by end users, please contact us. <\/span><\/span><\/p><\/div><\/div>\t\t\t\t<\/div>\r\n\t\t\t<\/div>\r\n\t\t\t\t\t\t

\r\n\t\t\t\tWhat is 3-wire work? <\/i><\/i><\/span>\r\n\t\t\t\t
\r\n\t\t\t\t\t

3-wire operation seals the signal input (the signal remains closed even after the button is pressed) and is also used to start the inverter with a push of a button. To enable 3-wire operation it is necessary to follow the circuit sequence. The minimum input time (t) for 3-wire operation is 1 ms and operation stops if forward and reverse operation commands are entered simultaneously. <\/span><\/span><\/p><\/div><\/div>\t\t\t\t<\/div>\r\n\t\t\t<\/div>\r\n\t\t\t\t\t\t

\r\n\t\t\t\tWhat is the difference between QuickStart-1 and QuickStart-2? <\/i><\/i><\/span>\r\n\t\t\t\t
\r\n\t\t\t\t\t

When the motor starts idling the inverter, the quick start function estimates and calculates the idle speed and helps the motor to run safely. This function can be used as a start function by selecting Quick Start-1 or Quick Start-2 depending on the application used. Quick Start-1 is a function that allows stable operation in the low speed range (10 Hz or less) if the direction of the start command is the same when the engine is idling and restarting. Normal speed may not be found if the direction of the run command is reversed when the engine is idling and restarting. The Quick Start-2 function is a function that performs stable speed seeking work regardless of engine idling direction or driving instructions. If the engine idle speed is low (below 10-15 Hz), the speed may not be correct as a possible disadvantage. <\/span><\/span><\/p><\/div><\/div>\t\t\t\t<\/div>\r\n\t\t\t<\/div>\r\n\t\t\t\t\t\t

\r\n\t\t\t\tWhat parameters should be entered into the inverter when establishing the connection between EtherCAD, PLC and S100? <\/i><\/i><\/span>\r\n\t\t\t\t
\r\n\t\t\t\t\t

In EtherCAD connection, synchronized data connection is provided via Process Data Object (PDO). Process data includes TxPDO sent from the inverter to the EtherCAD Master and RxPDO sent from the EtherCAD Master to the inverter. There are two types of profiles such as CiA402 and LS device profile. With the LS device profile(PDO3), the user can randomly match the data defined in the object dictionary of the inverter via COM31-COM38 and COM51-COM58. For the CiA402 profile, the control word is fixed with target speed, status word and speed actual value. <\/span><\/span><\/p><\/div><\/div><\/div><\/div>\t\t\t\t<\/div>\r\n\t\t\t<\/div>\r\n\t\t\t\t\t\t

\r\n\t\t\t\tWhat is sensorless vector control? <\/i><\/i><\/span>\r\n\t\t\t\t
\r\n\t\t\t\t\t

Sensorless vector control is the process of performing vector control without rotational speed feedback from the motor but with the estimated rotational speed of the motor calculated by the inverter. Compared to V\/F control, sensorless vector control can produce larger torque at a lower current level. For high performance operation , the characteristic of the motor connected to the inverter output should be measured. Before running the sensorless vector operation, you can use autotuning(AUTOUN) to measure the parameters. To run high performance sensorless vector control, inverter and motor capacities must be the same. If the motor capacity is more than two levels smaller than the inverter capacity, the control may be faulty. If you encounter this situation, change the control mode to V\/F control. When working with sensorless vector control, do not connect more than one motor to the inverter output.<\/span> <\/span><\/span><\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\t\t\t\t<\/div>\r\n\t\t\t<\/div>\r\n\t\t\t\t\t\t

\r\n\t\t\t\tLet's explain the MMC Function. <\/i><\/i><\/span>\r\n\t\t\t\t
\r\n\t\t\t\t\t
MMC stands for Multiple Motor Control and it uses an inverter to control multiple motors. This function is used to secure the flow from the auxiliary motor when the inverter is installed in the pump plant when insufficient flow rate cannot be transmitted to the main motor. For HVAC only, the H100 product contains five parameter elements on the multi-function relay output terminals: one to five relay outputs allowing the use of up to five auxiliary motors. The main motor controls the primary PID with a power supply from the inverter output, feedback from the pump pressure values and starts\/stops the secondary motor according to the set frequency. Route the input power to the inverter so you can use it as a power source to start the auxiliary motor. The H100 internal system has a series of sequences in which the auxiliary motor is started, which signals a relay to signal the motor to start the secondary motor. Parameters that affect this sequence include AP1-43: Starting Aux, AP1-49: Aux On\/Off Seq, AP1-55: Auto Ch Mode available.<\/span><\/span><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\t\t\t\t<\/div>\r\n\t\t\t<\/div>\r\n\t\t\t\t\t\t
\r\n\t\t\t\tHow to avoid mechanical resonance frequencies? <\/i><\/i><\/span>\r\n\t\t\t\t
\r\n\t\t\t\t\t

Use frequency hopping to avoid mechanical resonance frequencies. The inverter will avoid certain frequency ranges during acceleration and deceleration. The operating frequencies cannot be adjusted within the preset frequency hopping band.<\/span> When the operating frequency is increased while the frequency parameter setting value (voltage, current, RS-485 communication, keypad setting, etc.) is within the frequency jump band, the frequency is maintained at the lower limit value of the frequency band.<\/span> Then, the frequency will rise when the frequency parameter setting exceeds the frequency range used by the frequency skip band.<\/span><\/span><\/p>\t\t\t\t<\/div>\r\n\t\t\t<\/div>\r\n\t\t\t\t\t\t

\r\n\t\t\t\tAnalogue Input\/Output Setting <\/i><\/i><\/span>\r\n\t\t\t\t
\r\n\t\t\t\t\t
Q: There is a problem with the analog input output signal because the inverter does not recognize the input output correctly. For example, the controller gives 100% input speed, but the inverter only runs at 57 Hz. At the same time, when the inverter is operating at 30 Hz, the output frequency display shows only 29 Hz. Is there any solution to this problem? <\/span><\/span><\/div>
\u00a0<\/div>
A: Many unexpected situations can be encountered when the system is installed in the field, and analog input-output status is one of them. The main reason for analog is signal noise generated from existing systems of other devices integrated together. The following instructions may be a solution to running the inverter in the full speed range. First, for the input mismatch, you will need to change the analog input scaling. In the above case, it can be seen that the inverter only works up to 57Hz. It will be 9.5V recognized by the inverter. Input voltage can be controlled in IN-05. Whatever the reason, the maximum input is 9.5V. So, if the input voltage recognition scaling at IN-10_V1 Voltx2 is changed to 9.5V, the inverter will only receive analog input up to 9.5V. Second, for output mismatch, you will need to change the output scaling. Output scaling can be changed with the Gain and Bias parameter in OUT-02 & 03.<\/span><\/span><\/div><\/div>\t\t\t\t<\/div>\r\n\t\t\t<\/div>\r\n\t\t\t\t\t\t

\r\n\t\t\t\t\t

Please find the following two methods when applying the copy and history feature using the iS7 digital installer. 1) System without fieldbus communication When the control panel is a system without any fieldbus communication, it is correct to use CNF-46 to read parameters from CPU and CNF-47 to write to a new drive. Reading is copying from the CPU to the keypad and writing is pasting the settings from the current inverter to a new one. 2) System using fieldbus communication (options such as CC-link, CANopen, Profibus-DP) When an option card is connected to the inverter, all the settings made via the keypad are entered and the option card is saved in the CPU. It is therefore recommended to always go over a Comm. It is the update process using COM-94 to apply the fieldbus settings to the main control card of the inverter. Additionally, when copying and pasting the settings on the keypad, follow these steps: 1) CNF-48=Saving Parameters: This operation saves the dialog group settings to the main control board. 2) CNF-46= Parameter Reading and CNF-47=Parameter Writing: It is exactly the same process as non-fieldbus option type. 3) COM-94= Comm. Update: Applies the copied communication settings to the new inverter.<\/span> <\/span><\/span><\/p><\/div><\/div>\t\t\t\t<\/div>\r\n\t\t\t<\/div>\r\n\t\t\t\t\t\t

Obviously, \u201cTorque limit\u201d and \u201cStall prevention\u201d are similar because both functions limit the output current.<\/span> But they have different working conditions.<\/span> \u201cTorque limit\u201d operates based on peak current and \u201cStagnation prevention\u201d operates on RMS (Root Mean Square) value of current.<\/span> The current value displayed on the keypad is the RMS value.<\/span> Therefore, the output current appears to be limited below the torque limit.<\/span> The peak value can be obtained by multiplying the RMS current by the root of two.<\/span><\/span><\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/div>\t\t\t\t<\/div>\r\n\t\t\t<\/div>\r\n\t\t\t\t\t\t
