An active constantspeed overrides the drive speed reference. See sectionConstant speeds on page 61.26.01 Const speed func Determines how constant speeds are selected, and whetherthe rotation direction signal is considered or not whenapplying a constant speed.No. Name/Value Description FbEqBit Name Information0 Const speedmode1 = Packed: 7 constant speeds are selectable using the three sourcesdefined by parameters 26.02, 26.03 and 26.04.0 = Separate: Constant speeds 1, 2 and 3 are separately activated bythe sources defined by parameters 26.02, 26.03 and 26.04 respectively.In case of conflict, the constant speed with the smaller number takespriority.1 Dir ena 1 = Start dir: To determine running direction for a constant speed, thesign of the constant speed setting (parameters 26.06…26.12) ismultiplied by the direction signal (forward: +1, reverse: -1). For example,if the direction signal is reverse and the active constant speed isnegative, the drive will run in the forward direction.0 = Accord Par: The running direction for the constant speed isdetermined by the sign of the constant speed setting (parameters26.06…26.12).
