Description: Sets the motor cooling system used.
Value: 0: Natural ventilation
1: Forced cooling
2: Liquid cooling
128: No fan
Dependency: For 1LA7 motors (p0300), the parameter is pre-set as a function of p0307 and p0311.
NOTICE
When selecting a catalog motor (p0301), this parameter is automatically pre-assigned and is write protected.
Information in p0300 should be carefully observed when removing write protection.
Note
The parameter influences the thermal 3-mass motor model.
1LA7 motors, frame size 56 are operated without fan.
