Cause : I2t motor comes when the parameterized limit value for the I2t monitoring of the motor has been exceeded. This means the temperature of the motor connected to the drive has reached a pre-defined threshold but is still below the critical trip point.

The A029 alarm in siemens master drive a motor temperature alarm. This means the motor temperature is exceeding its normal operating range.

Motor duty cycle is exceeded, check the following parameters:

• P362 motor cooling.
• P363 mot. temp. T1.
• P364 mot. load limits.
