Function:
No external fan is required, that is
the motor is derated at low speed.
Applies an external motor fan
(external ventilation), so no
derating of the motor is required at
low speed. The upper curve in

lower than nominal motor current
(see parameter 1-24 Motor Current).
If the motor current exceeds
nominal current, the operation time
still decreases as if no fan was
installed.

The maximum value depends
on the rated motor current.
Avoid 100% current for too
long. It may damage the
motor.
Low values of DC hold
produce larger than expected
currents with larger motor
power sizes. This error
increases as the motor power
increases.
Enter a value for holding current as
a percentage of the rated motor
