Provisions
In order to make the commissioning procedure easier and uniform, the system contains a clause referring to the
speed and torque directions to be respected:
As a general rule the winder speed and the torque direction are considered positive with a upper winding side.
All the possible system configurations stated in the examples below refer to this clause.

The polarity of the line speed reference is not important, because the system states the output
reference polarity only according to the parameters

and

Figure 6.17.13: Drive used as a winder – winding side = up
If the speed demand function is used, the system creates a positive speed reference; it is therefore necessary to
connect the motor so that, with this polarity, the coil winds the material starting from the upper side. The wind

ing torque is positive.
