Setting Polecount
Attention!
Before commissioning, it is absolutely essential to enter the number of poles of the motor that is
connected.
If the number of poles is set incorrectly, it is possible that the motor will be overloaded by too high a
rotational speed, thus resulting in damage to the motor.

Attention!
It is essential to check the direction of rotation of the fan during the initial commissioning.
To do this, note the direction of the arrow on the fan housing. We will not be responsible under any
circumstances for warrantee for damage caused because the direction of rotation is wrong!
Rolling direct.
The correct rotary direction depends on the type of fan.
The factory preset is rotary direction

.
Find the fan in the following table to determine the
correct rotary direction and to subsequently program. In
motors (MK.. or MW..), the rotational direction to be
programmed depends on the installation.

Information
If the direction of rotation is to be reversed and the speed of the motor is still greater than 30 rpm, the
brakes attempt to reduce the speed. If, after 60 sec, the speed is still greater than the threshold value,
braking is aborted and the error
“
Generator operation
”
is triggered. Also, the request for direction-
rotation reversal is deleted (and the parameter is overwritten with its old value).
