Technical Parameters for NJ301-1100 Homing Configuration

Understanding Homing Parameters for NJ301-1100 Servo Motor

When configuring homing for your NJ301-1100 Omron Servo Motor, it is essential to understand the technical parameters that influence the process. The NJ301-1100 is designed to operate within specific parameters to ensure accurate and reliable homing. Key parameters include the homing speed, homing sensitivity, and homing offset. These parameters can be adjusted in the Sysmac Studio software to match the specific requirements of your application.

The homing speed determines how quickly the motor moves to the home position. A higher speed can reduce the time required for homing but may also increase the risk of overshooting the home position. Conversely, a lower speed can provide more precise homing but may take longer. The homing sensitivity controls the motor’s ability to detect the limit switches accurately. Proper sensitivity ensures that the motor stops precisely at the home position without missing the limit switch. The homing offset allows for fine-tuning the home position to account for any discrepancies between the physical limit switches and the motor’s zero position.

Setting Up Homing Without External Signal in Sysmac Studio

To set up homing without an external signal in Sysmac Studio, you need to configure the system to use the limit switches as the reference points. This method, known as “Solo Ingressi Limite,” relies on the internal limit switches of the NJ301-1100 servo motor. Begin by navigating to the Configuration Control Assi section in Sysmac Studio and selecting Impostazione Asse. Choose the axis you want to configure and access the Impostazioni Ricerca d’Origine option.

In the Impostazioni Ricerca d’Origine section, select the Metodo Ricerca d’Origine – Solo Ingressi Limite option. This method uses the internal limit switches to determine the home position. Set the research method to posizione zero preimpostata (pre-set zero position) in the research origin section. This setting ensures that the motor does not move during the homing process but sets the Homed status to high once the limit switches are detected.

Configuring Pre-set Zero Position for Accurate Homing

Configuring the pre-set zero position is crucial for accurate homing. The pre-set zero position is the point where the motor is considered to be at the home position. To configure this, ensure that the limit switches are properly installed and calibrated. The limit switches should be set to trigger at the desired home position, which should be aligned with the motor’s zero position.

In Sysmac Studio, you can set an offset if needed to fine-tune the home position. This offset allows for adjustments to account for any discrepancies between the physical limit switches and the motor’s zero position. After setting the offset, save and apply the settings to your axis. It is recommended to verify the homing status and motor position to ensure that the homing process is accurate. If necessary, revisit the Impostazioni Ricerca d’Origine section and adjust the parameters as needed.

Note: Refer to the FB MCHome function’s specific guide for detailed information on the homing process. Access the guide by selecting the function from the list and pressing F1.

Common Troubleshooting

Issue: Homing Not Executing

Symptoms:

The servo motor does not perform the homing process even after issuing the MCHome or MCHomeWithParameter functions.

Solution:

Ensure that the “Solo Ingressi Limite” method is correctly selected in the Configuration Control Assi -> Impostazione Asse section. Verify that the “Impostazioni Ricerca d’Origine” option is set to “Metodo Ricerca d’Origine – Solo Ingressi Limite.” Additionally, check if the “posizione zero preimpostata” (pre-set zero position) is correctly configured in the research origin section. If the issue persists, consult the FB MCHome function’s specific guide by selecting the function and pressing F1. Refer to section 14 for detailed operational principles.

Issue: Incorrect Axis Selection

Symptoms:

The system does not recognize the selected axis for homing, leading to errors or no response.

Solution:

Double-check the axis selection in the Configuration Control Assi -> Impostazione Asse section. Ensure that the correct axis is chosen and that it is properly configured for homing. Verify the axis settings and make sure there are no conflicts with other axes or parameters. If the problem continues, review the startup guide for axis configuration.

Issue: Homing Offset Not Applied

Symptoms:

The homing offset is not being applied correctly, causing the motor to be positioned incorrectly after homing.

Solution:

In the “Impostazioni Ricerca d’Origine” section, ensure that the offset is set correctly. If the offset is not applied, verify that the parameter is not disabled or overridden by another setting.

Symptoms:

After performing the homing process, the Homed status does not change to high, preventing further operations.

Solution:

Confirm that the “posizione zero preimpostata” (pre-set zero position) is correctly configured in the research origin section. This setting should set the Homed status to high without moving the motor. If the status remains low, check for any errors in the system logs and ensure that the homing process is completed successfully. Refer to the FB MCHome function’s specific guide for troubleshooting steps.

Issue: Homing Function Not Responding

Symptoms:

The homing function does not respond to commands, and the motor does not move or perform any action.

Solution:

Verify that the servo drive is properly connected and powered. Check the communication settings between the servo drive and the control system. Ensure that the firmware of both the servo drive and the control system is up to date. If the issue persists, reset the servo drive and reconfigure the homing settings. Consult the Omron technical support for further assistance if needed.
