7.2.3  Velocity polarity
In parameter S-0-0043 the polarities (preceding signs) of the specified velocity data 
can be inverted according to the application. The polarities are not inverted within a 
controlled system, but outside of it (at the input and output). A positive velocity setpoint 
difference with non-inverted polarity means the direction of rotation is clockwise, look-
ing at the motor shaft.
