This parameter sets the temperature at which a warning will occur for heat sink monitoring.
If this parameter is set at 110.0°C and the GS4 drive temperature reaches 110.0°C, the drive will
trigger an error and stop, instead of just warning. The heat sink FAULT level is 110°C and cannot be
changed.
For Frame C and above, when IGBT temperature reaches (P6.30 setting minus 15°C), the heatsink
fan will accelerate to the highest speed. When IGBT temperature is lower than (P6.30 setting
minus 35°C), and capacitor temperature is lower than (OH2 capacitor warning level minus 10°C),
the heatsink fan will return to its setting speed.
If this parameter is set lower than 35°C, the level will remain at 35°C.

* The over heating warning levels for OH1 and OH2 are 5°C less than the listed
fault temperatures.
CT = Constant Torque (normal duty).
VT = Variable Torque (light duty).
Related parameters: P6.39 & P6.40 determine the Motor Overheating Level (OH3)
