Installation/Wiring 1-27
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 - A054 [Digital Inx Sel] is
set to option 2, 4, 5, 6, 11, 12, 13, 14, 15 and the digital input is active, or if A132 is not set to
option 0, the speed reference commanded by P038
[Speed Reference] will be overridden. See
the chart below for the override priority.
