6.1 Thermal motor protection
Caution
The integrated temperature sensor protects the synchronous against an overload condition
Shaft height 11 to 48 to 2 • I
From shaft height 63 up to 4∙ I
For load applications that are critical from a thermal perspective - e.g. overload when
the motor is stationary or an overload of M
