4.3.2 Current ratings
Power losses cause the drive to increase its temperature according to:
As power losses have a positive correlation with the motor RMS current, when the ambient temperature rises, the
output current must be limited to avoid an excessive drive temperature (T
P
< 110 ºC). The threshold temperature
where the current derating should start mainly depends on the DC bus voltage.

Notes
Maximum absolute power
stage
temperature
110
ºC
Measured on the PCB (not the heatsink) and accessible via
register.
Thermal resistance from
power stage to the heatsink
0.01
7
ºC/W
Does not consider the thermal resistance of the heatsink, but
assumes
the cold plate is a thermal conductor, not the thermal
dissipator.
Thermal resistance from
power stage to air
5
ºC/W
Considering the drive is vertical and free air convection with is
allowed on the cold plate surface (> 30 cm clearance around
the drive).
Mounting the drive without heatsink could only be done for
very low load applications or debugging purposes, otherwise,
over-temperature alarm will occur after a few minutes of
operation.
