6.5 Start and Speed Reference Control
The drive speed command can be obtained from a number of
different sources. The source is normally determined by P038
(Speed Reference). However, when A051 or A052 (Digital Inx
Select) is set to option 2, 4, 5, or 6, and the digital input is active,
A051 or A052 will override the speed reference commanded by
P038 (Speed Reference). See figure 6.2 for the override priority.
