Forced ventilation (FV) units
In some applications the fan built on to the motor
shaft do not give sufficient cooling for operation at
low speed (see drawing on page 84). That problem
is solved by mounting a FV unit.
Typical applications are for example conveyors,
spindles and other contant torque (CT) applications
where the customer wants a wide control range
down to low speed.
The FV unit is available in 2 versions. The
characteristics of the two versions are the same.
The variable factors are the length and the placing
of the terminal box.
The VLT Drive Motor yields full continuous torque
down to low speed with FV built on.

The VLT Drive Motor can be delivered with an electo
mechanical brake, which is controlled by the
frequency converter. See parameter 138 and 139
for adjustment.
