Only if <1> are not met.
<3> Only if p0612.8 = 1.
<4> p0605 also defines the target temperature for p0034 = 100 %. Therefore, p0605 has no influence on the time up to alarm A07012.
<5> If p0610 = 12.
<6> The lower p0611 and the lower the reference current of the motor temperature model 1 (I2t), the faster A07012 is reached.
