Parameter Description
1-91 Motor External Fan
Option: Function:
[0] No No external fan is required, i.e., the motor is derated at
3 3
low speed.
[1] Yes Applies an external motor fan (external ventilation), so
that no derating of the motor is required at low speed.
The upper curve in graph above (fout = 1 x fM,N) is
followed if the motor current is lower than nominal
motor current (see 1-24 Motor Current). If the motor
current exceeds nominal current, the operation time still
decreases as if no fan were installed.
