Cause : Motor temperature model 1 overtemperature comes when the thermal I2t motor model for synchronous motors identified that the alarm threshold was exceeded.

See also: r0034 (Motor utilization), p0605 (Mot_temp_mod 1/2 threshold), p0611 (I2t motor model thermal time con- stant), p0612 (Mot_temp_mod activation)

- check the motor load and if required, reduce.
- check the motor ambient temperature.
- check the thermal time constant (p0611).
