Control Terminal Connections
For standard applications and operation, the basic control of the drive and functions of all drive input terminals can be configured using just
two parameters, P-12 and P-15. P-12 is used to define the source of all control commands and the primary speed reference source. P-15 then
allows fast selection of Analog and Digital Input functions based on a selection table.
