This setting has no effect when the analog source data is forced.

4.6.5

Force Percentage

When the analog source data is set to forced, the analog output voltage is controlled by the force 

percentage configuration value. It indicates the percentage of analog full scale to output. For example, if the
analog output range is –10 to 10V, a force percentage of 35.4 will cause an output voltage of -2.92V.

This setting has no effect when the analog source data is position or velocity.
