Drive unit without /DI option

The following derating applies for operating the drive unit without "/DI" option in the ambient temperature range from +40 °C to +60 °C:

The thermal speed/limit torque characteristic curve is re-scaled towards the origin (minimized). The thermal operating point based on rms torque and thermally effective speed of the application must be below the re-scaled characteristic curve.

TU	Ambient temperature [°C]
M0	Standstill torque under nominal conditions
M0(TU)	Standstill torque at increased temperature 40 °C < TU < 60 °C
nN	Rated speed
nN(TU)	Rated speed at increased temperature 40 °C < TU < 60 °C
Ke	Transmitter factor = 1
