+3.3V Power Supply Fault

What does P3.3V mean?

The P3.3V (Green) LED indicates that the internal power supply circuit of the servo amplifier is normally outputting +3.3 V. If this LED does not light, it signifies a failure in the +3.3V power supply within the servo amplifier, which is critical for its internal logic.

• Internal +3.3V power supply within the servo controller or related module has failed.
• Short circuit on a +3.3V power line.
• Overload condition on the +3.3V power rail.
• Faulty voltage regulator for the +3.3V supply.
• Component failure on the power supply board.
