The fault protection if no motor is detected
is a combination of parameters Pr.31-33.
The drive will carry out the action set in
parameter Pr.31 whenever the current
flowing within the motor does not exceed the
value defined in parameter Pr.32 during the
time defined in parameter Pr.33.

As the cooling fan is
connected to the motor
axis, the cooling effect
varies based on motor
speed. Most universal
induction motors have
this design.

FORCED
Additional power is
supplied to operate the
cooling fan. This
provides extended
operation at low speeds.
Motors designed for
drives typically have this
design.
