Signals and monitoring functions - Thermal motor model 1 (I2t)
<1> Only if there is a temperature sensor (p0601 = 2).
<2> Only if <1> are not met.
<3> Only if p0610.12 = 1.
<4> p0605 also determines the target temperature at r0034 = 100 %. Thus, p0605 does not influence the time up to warning A07012.
<5> If p0610 = 12.
<6> The lower p0611 and the lower the reference current of the thermal motor model 1 (I2t), the faster A07012 is reached.
Only for:
- Permanent-magnet synchronous motor (PMSM)
- Reluctance synchronous motor (RESM)
