| Version Number | Description |
|---|---|
| 1.0 | Initial version, Explains how to setup a Full Closed Loop option card to enable an external encoder axis in iCE |
iC92XX firmware >= 2023.3
iCube Engineer >= 2023.3
1. Hardware and Software Components
| Component Name | Version |
|---|---|
| iCube Engineer | ≥ 2023.3 |
| SGDV Feedback Option card (SGDV-OFA01A) | |
| SGD7S | ≥ 002F |
| iC9226M-EC | ≥ 2023.9 |
2. Solution details
- Open a project in iCube Engineer
- Add the servo to which the option card is attached.
- In the Components window search for the SGDV Feedback Option Card and drag it to the Servopack in the plant that has the option card attached.
- An external servonet axis will appear in the Motion Axis section
- Open the settings section for the "Feedback Option Card module" in the PLANT
- Under the Feedback section set the Operation mode to "Semi-closed loop + external encoder monitoring"
- Notification will appear in iCube signifying that Pn00E.3 was adjusted.
- Open the parameter window of the SERVOPACK with the option card.
- Verify and write Pn00E.3 to the RAM of the SERVOPACK and then to the ROM, Then power cycle the system
- If the motor rotation for the forward direction needs to be changed Pn00E.3 may need to be changed as well
- Set the resolution of the external encoder in the Axis options page.
- User units for the External Encoder can be defined in the "Motion Axis" configuration menu.
- Motion on the external encoder axis can be verified using PLCopenPart1 FBs.
