Why does an ATV12 not power up or display anything on the screen?

Troubleshooting Steps

1. Verify the incoming mains voltage at terminals L1, L2, and L3.
2. Measure the DC bus voltage to confirm the drive is receiving and converting power correctly.
3. Check the control terminal DC power supplies for the correct voltage levels.
4. Inspect the +24 VDC supply on the control terminals. If external devices are connected, disconnect them temporarily and check whether one of them is pulling down the power supply.
5. If the drive remains inoperative after these checks, the ATV12 may have an internal hardware failure.

Note: Replacement parts are not available for the ATV12 drive. If the unit is confirmed to be faulty, the recommended solution is to replace the drive.
