8.2.3 Speed polarity
The polarities (sign) of the speed data stated can be changed in parameter S-0-0043 to
suit the application. The polarities are not changed inside a control loop, but outside (at
the input and output). If the speed reference value difference is positive and the polarity
is not inverted, the rotation is clockwise looking at the motor shaft.
