3. Power board fault judgment

Use the DCIN and DCOUT indicators to judge whether the power board is faulty.

4. Power board fault phenomenon and countermeasures

A. The PSEMG (red) indicator on the power board is on

The emergency stop button connected to the EMG is valid, or the EMG connector is disconnected to release the emergency stop button, or check the EMG connector.

Note: Emergency stops are divided into external emergency stops and internal emergency stops. When the PSEMG indicator is on, it can be judged as an external emergency stop.
