What should I do if a Delta robot shows the alarm “EC015 NAND Flash data checksum error"?

This alarm indicates a bad block in the internal memory of the robot controller. For a robot with firmware version v7402_033 or above, the system will automatically repair when the controller starts up. Users only need to clear the alarm.

For earlier firmware versions (below v7402_033), please refer to the following steps.

To manually trigger NAND Flash repair:

1. Launch Delta Robotic Automation Software DRAStudio > Parameter > Controller > Setting Parameters

2. Fill in “0x4E41434C” to the value column of P1-08 and “1” to P1-09

3. Restart the robot controller to complete the repair
