[Power sequence board] Temperature inside the control cabinet too high. (for E0x series controllers)

Error handling: Motor power OFF.
Error reset: Possible.

Description: The thermostat contact on the power sequence board that monitors the controller's internal temperature has activated (70°C).

Main causes:

1. The rotational speed of the cooling fan inside the controller has decreased.

2. The ambient temperature around the controller has risen to 45°C or higher.

3. A problem with the power sequence board.

Countermeasures:

1. If “W1053 (FANXX) Fan rotational speed decreased. (Servo board XX)” appears at the same time, refer to the countermeasures for W1053.

2. Check that the controller ambient temperature is 45°C or lower.

3. Replace the power sequence board.
