Analog to Digital<\/strong>.<\/p>\n\n\n\nIts purpose is to convert an analog electrical signal into a digital value that can be processed and displayed by the controller.<\/p>\n\n\n\n
Within ESTUN E315P System Diagnostics, AD Diagnostics is used to determine whether the analog input status is correct. The interface can also be used for voltage calibration.<\/p>\n\n\n\n
This function is useful when a machine component provides an analog feedback signal and technicians need to verify whether the E315P is receiving the expected voltage.<\/p>\n\n\n\n
How to Perform AD Diagnostics<\/h2>\n\n\n\n
Before testing, connect the motor or related component according to the requirements shown in the machine’s wiring diagram.<\/p>\n\n\n\n
After the motor runs, observe the corresponding AD value displayed on the System Diagnostics interface.<\/p>\n\n\n\n
According to the manual, the interface displays the voltage value fed back by the potentiometer on the motor<\/strong>.<\/p>\n\n\n\nThe diagnostic process can therefore be understood as:<\/p>\n\n\n\n
Motor potentiometer \u2192 Analog voltage feedback \u2192 E315P AD input \u2192 Displayed voltage value<\/strong><\/p>\n\n\n\nIf the displayed voltage corresponds with the expected feedback condition, the analog input signal is being detected.<\/p>\n\n\n\n
If the value is missing or does not correspond with the actual machine condition, technicians should inspect the related signal and wiring before changing unrelated parameters.<\/p>\n\n\n\n
Why Is AD Voltage Calibration Important?<\/h2>\n\n\n\n
The AD Diagnostics interface also supports voltage calibration.<\/p>\n\n\n\n
Because the controller uses analog voltage as input information, the displayed value should correspond accurately with the actual feedback voltage.<\/p>\n\n\n\n
When checking an analog input problem, technicians should therefore distinguish between two situations: whether the signal is physically reaching the controller and whether the displayed voltage correctly represents that signal.<\/p>\n\n\n\n
This distinction can make ESTUN E315P System Diagnostics more useful when troubleshooting analog feedback problems.<\/p>\n\n\n\n
What Is DA Diagnostics?<\/h2>\n\n\n\n
DA<\/strong> means Digital to Analog<\/strong>.<\/p>\n\n\n\nWhile AD converts an analog input into information the controller can process, DA works in the opposite direction. It converts a controller-generated digital value into an analog output signal.<\/p>\n\n\n\n
DA Diagnostics is therefore used to determine whether the E315P’s analog output is correct.<\/p>\n\n\n\n
The basic test involves setting a target output voltage in the controller and then measuring the corresponding physical output with a multimeter.<\/p>\n\n\n\n
How to Perform DA Diagnostics<\/h2>\n\n\n\n
Open the DA section of the ESTUN E315P System Diagnostics interface and select DA01 Voltage Value U1<\/strong>.<\/p>\n\n\n\nEnter the required target voltage value.<\/p>\n\n\n\n
The controller should then generate the corresponding analog voltage at the selected output port.<\/p>\n\n\n\n
Use a multimeter to measure the actual voltage at the output terminal.<\/p>\n\n\n\n
Compare:<\/p>\n\n\n\n
Target voltage set in the E315P<\/strong> avec Actual voltage measured by the multimeter<\/strong><\/p>\n\n\n\nThe two values should correspond within the expected system condition.<\/p>\n\n\n\n
This comparison provides a direct method for determining whether the analog output is responding to the controller command.<\/p>\n\n\n\n
What If the DA Output Does Not Match the Set Value?<\/h2>\n\n\n\n
If the measured voltage does not correspond with the target value, avoid immediately changing unrelated machine parameters.<\/p>\n\n\n\n
First confirm that the correct DA channel and output terminals are being measured. Check the wiring diagram and verify that the multimeter is connected to the intended output.<\/p>\n\n\n\n
Then compare the controller setting with the actual measurement again.<\/p>\n\n\n\n
The key purpose of the DA test is to separate the commanded value<\/strong> from the physical output value<\/strong>. This makes it easier to determine whether further inspection should focus on the analog output circuit or another part of the machine.<\/p>\n\n\n\nHow Does Encoder Diagnostics Work?<\/h2>\n\n\n\n
The third function within ESTUN E315P System Diagnostics is Encoder Diagnostics.<\/p>\n\n\n\n
Its purpose is to determine whether external encoder signals are functioning normally.<\/p>\n\n\n\n
Instead of comparing voltage values, this diagnostic function observes changes in the corresponding C-Pulse<\/strong> value.<\/p>\n\n\n\nWhen the encoder generates signals, the associated C-Pulse value should change.<\/p>\n\n\n\n
The diagnostic relationship can therefore be understood as:<\/p>\n\n\n\n
Encoder movement \u2192 Pulse signal \u2192 E315P detection \u2192 C-Pulse value change<\/strong><\/p>\n\n\n\nIf the expected C-Pulse value changes during encoder operation, the controller is detecting the encoder signal.<\/p>\n\n\n\n
How to Check an Encoder Signal<\/h2>\n\n\n\n
Open the Encoder section of the System Diagnostics interface and identify the encoder being tested.<\/p>\n\n\n\n
Operate or move the corresponding mechanism as required and observe the C-Pulse value.<\/p>\n\n\n\n
The important point is whether the value changes in response to the encoder signal.<\/p>\n\n\n\n
If the C-Pulse changes normally, the controller is receiving encoder feedback. If no change occurs, further inspection of the encoder signal path may be required.<\/p>\n\n\n\n
This provides a straightforward method for checking signal presence before proceeding with more detailed troubleshooting.<\/p>\n\n\n\n
How to Choose the Correct Diagnostic Function<\/h2>\n\n\n\n
Choosing the correct test is one of the most important parts of ESTUN E315P System Diagnostics.<\/p>\n\n\n\n
Utiliser AD Diagnostics<\/strong> when checking an analog signal entering the E315P, such as voltage feedback from a motor potentiometer.<\/p>\n\n\n\nUtiliser DA Diagnostics<\/strong> when checking whether the controller generates the expected analog output voltage.<\/p>\n\n\n\nUtiliser Encoder Diagnostics<\/strong> when checking whether an external encoder produces a signal that the controller can detect.<\/p>\n\n\n\nFollowing this signal-based approach helps technicians avoid mixing different diagnostic methods. By identifying whether the problem involves analog input, analog output, or encoder feedback first, the appropriate diagnostic function can be selected and the electrical signal path can be checked more efficiently.<\/p>\n\n\n\n
Frequently Asked Questions\uff08FAQ\uff09<\/h2>\n\n\n\n
\n
\n
What Should I Check Before Measuring an Analog Signal?<\/h3>\n\n\n
Confirm the correct diagnostic channel and terminal using the machine’s electrical diagram. Also verify that the measuring instrument is set for the expected voltage type and range. This helps prevent an incorrect measurement from being mistaken for a controller problem.<\/p>\n\n<\/div>\n<\/div>\n
\n
Why Should a Multimeter Be Used for DA Testing?<\/h3>\n\n\n
The value shown in the controller represents the commanded output, while a multimeter verifies the voltage physically present at the output terminal. Comparing these two values helps determine whether the expected analog command is actually being produced.<\/p>\n\n<\/div>\n<\/div>\n
\n
What Information Should I Provide When Requesting Technical Support?<\/h3>\n\n\n
Record the diagnostic function used, the selected channel, controller-displayed value, actual multimeter measurement where applicable, and the machine response during testing. For encoder problems, record whether the C-Pulse changes during movement. Photos or videos of the diagnostic screen can also make remote troubleshooting more efficient.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n
Conclusion<\/h2>\n\n\n\n
ESTUN E315P System Diagnostics provides dedicated methods for evaluating analog inputs, analog outputs, and external encoder signals. AD Diagnostics helps verify analog feedback and supports voltage calibration, while DA Diagnostics allows technicians to compare a commanded voltage with the actual output measured by a multimeter. Encoder Diagnostics uses C-Pulse changes to determine whether an external encoder signal is being detected.<\/p>\n\n\n\n
For effective troubleshooting, technicians should first identify the signal type and then select the appropriate diagnostic function. Measurements should always be compared with the actual wiring and machine response rather than relying on the controller display alone.<\/p>\n\n\n\n
