If one preset speed isrequired, one logic input must be assigned. Two logic inputs must be assigned ifthree preset speeds are required.The preset speeds are adjustable from 0.1 to 72 Hz. The actual running speed islimited to the setting of High Speed. The programmed values must increaseconsecutively from speeds 1, 2, and 3. If both logic inputs are low, the speed willbe the speed reference, if present, or low speed. The factory preset value for onePreset Speed is 5 Hz, for three Preset Speeds 5, 10, and 15 Hz.Table 29 gives input states for activation of 3 Preset Speeds. If 1 Preset Speed hasbeen selected, the speed is active when the assigned input is high.78 © 1996 Square D All Rights Reservedηττπ://νιχοντρολσ.χοm
