Error 8060 on Bosch Rexroth IndraDrive indicates an overcurrent in the power section. To resolve this issue for five machines, follow these steps for each machine:

1. Check the Load and Connections – Verify that the motor and power connections are correct and not causing excessive current draw.
2. Inspect the Power Section – Look for any visible damage or overheating signs in the power section.
3. Restart the System – Power off the drive, wait for the DC bus to discharge below 50V, and restart.
4. Adjust Parameters if Needed – Ensure that the drive’s current limits and motor settings are correctly configured.
5. Replace Faulty Components – If the issue persists, the power section may be defective and require replacement.

Repeat these steps for all five machines to ensure proper operation.
