IGBT Over-temperature (Hardware)

¿Qué significa 31 ?

The IGBT Inverter Bridge's over-temperature protection has activated, indicating excessively high short-term overload current. This typically points to the motor drawing too much current, potentially due to incorrect sizing or heavy load conditions, causing the inverter's power semiconductors to overheat.

• The temperature of the Insulated-Gate Bipolar Transistors (IGBTs) has exceeded the hardware limit.
• Inadequate cooling (fan failure, blocked heatsink) causing IGBT overheating.
• Overcurrent or overvoltage stress on the power electronics.

1. 1

   Inspect the motor's current loading and reduce if exceeding nominal values.

2. 2

   Verify the motor's nominal current and power against the AC drive's rating to ensure proper sizing.

3. 3

   Perform an identification run to optimize motor parameters and drive control.
