Derating for increased ambient temperature
The following derating applies for operating the drive unit 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.
