An inversion internally inverts the sign of the analog setpoint at this terminal. The motor direc-
tion of rotation is reversed.

No inversion

Inversion
There is the following assignment between inversion, direction of rotation, and setpoint:
Without inversion, the motor rotates clockwise for a positive setpoint
With inversion, the motor rotates anti–clockwise for a positive setpoint
Definition of the direction of rotation:
When viewing the output shaft, the shaft rotates counter–clockwise
The motor direction of
rotation is counter–clockwise
When viewing the output shaft, the shaft rotates clockwise
The motor direction of rotation
is clockwise

If the motor still continues to turn even with a speed setpoint of 0 V, and this is not desired, then
this parameter can be used to enter a voltage offset to adjust the analog input for zero output.
