This is a new series of articles in which we will use OMRON’s R88D-1SN -ECT AC servo system to perform various validations. We start by setting up the servo and running the tool.
Come on, let’s enjoy FA.
Foreword
Thank you from the bottom of my heart for visiting my technical blog and YouTube channel.
We are currently running the “Takahashi Chris” radio show with Full-san (full＠桜 八重 (@fulhause) / X) which I deliver every Wednesday night.
Sharing, not hoarding, technical knowledge
We publish technical information related to factory production technology and control systems for free, through blogs and videos.
With the belief that “knowledge should be accessible to everyone,” we share practical know-how and real-world troubleshooting cases from our own field experience.
The reason we keep it all free is simple: to help reduce the number of people who struggle because they simply didn’t know.
If you’ve ever thought:
- “Will this PLC and device combination actually work?”
- “I’m having trouble with EtherCAT communication—can someone test it?”
- “I want to try this remote I/O, but we don’t have the testing environment in-house…”
Feel free to reach out!If lending equipment or sharing your configuration is possible, we’re happy to verify it and share the results through articles and videos.
(We can keep company/product names anonymous if requested.)
How can you support us?
Currently, our activities are nearly all unpaid, but creating articles and videos takes time and a proper testing environment.If you’d like to support us in continuing and expanding this content, your kind help would mean a lot.

Technical knowledge shouldn’t be kept to ourselves.
Implementation
wiring
This is an example of wiring for OMRON’s R88D-1SN series.
USB connection to the servo
Connect the PC to the OMRON R88D-1SN using a USB cable.
Start Sysmac Studio and click Online>Connect to Device.
The Connec to device configuration screen is displayed and ‘Drive’ is set from the drop-list.
Next, select Direct connect via USB and connect to the Servo Drive with Connect.
Done!
The Sysmac Studio automatically switches to the configuration and commissioning screen.
Mode
Device Group>Double-click on the servo to be commissioned, you can now set the operating mode of the servo.
initialisation
To initialise the OMRON servo, right-click on the servo>Initialize to reset the device.
This is the servo initialisation setting screen.
- Area to restore sets Parameters and Safety to reset all parameters.
- Drive restart is set to Yes to automatically restart the servo.
Setup and Tuning
Now we will set up the servo, so right-click on the servo>Setup and Tuning.
This is the OMRON servo setup screen.
Quick Parameter And I/O Monitor
Click on the orange button in the diagram below to set up the servo.
Proceed with Yes.
Motor and Encoder Setting
Here you can set the motor and encoder settings screen, including forward and reverse rotation and the encoder type to be used, depending on the application.
When all settings are complete, proceed with Next>.
Input Signal
This sets the use of each input terminal of the servo.
Set IN1/IN2/IN3 to None as you are not wiring error inputs etc. again in this article.
Once all settings have been completed, transfer the parameters via Transfer to Drive.
Yes to restart the servo.
Test Run
On the right-hand side of the Input Signal Settings screen is the Test Run screen, where Servo ON changes the servo to Test Run mode.
Proceed with Yes.
Done!The servo is currently set from Sysmac Studio to Servo On.
Configuration
In the Configuration area, set the Operation Mode and speed, etc., then click Apply to apply the settings.
Start Run
Click on the button with the orange frame in the diagram below to start the servo moving.
Button 1 is a counter-clockwise command and Button 2 is a clockwise command.
Once you have completed the Test Run operation, proceed with Next>.
Output Signal
Set the servo output signal also according to the application and proceed with Next>.
Finish
Finally, check all parameters and complete the configuration with Finish.
Status Monitor
Use the Status Monitor command to monitor the servo status.
Current servo signals etc. can be checked.
Motor And Encoder
The OMRON servo used in this article is not new, so the encoder and other components need to be reset. The “Motor and Encoder” command is used for this purpose.
Click on ‘Reset Motor Replacement Detection error’ in the Encoder Properties.
Troubleshooting
Use the “Troubleshooting” command to check the servo error status.
You can check the current servo error messages and other information on this screen.
Damping Control
Use the Damping Control command if you want to test drive a servo, such as Jog.
This is the servo operation screen.
Servo ON
Servo ON first.
Jog
To make the servo jog, open the Jogging Tab, set the appropriate speed etc. and apply the settings using the Apply button.
The button with the orange frame can now be pressed and the servo can be rotated forward or reverse by clicking it.
Signle Step
To let the servo do constant speed and positioning, open the Single Step tab.
Set the speed and other parameters required for Single Step operation and click on the button with the orange frame to move the servo.
Forward and reverse rotation can be changed from the Movement Direction drop-list.
Parameters
All servo parameters can be set via the tool.
Data Trace
The last feature we want to introduce is the trace function, and to use it, click Data Trace Settings>Add>Data Trace.
This is the data tracing screen.
Add the data you want to monitor and click on the red circle record. Then click the square button next to it when the data collection is complete.
Next, click on the Play button and you can check the trace you have just recorded.
Done!
