72ACS 400 User’s ManualGroup 12: Constant SpeedsThe ACS 400 has 7 programmable constant speeds, ranging from 0 to 250 Hz. Negative speedvalues cannot be given for constant speeds.Constant speed selections are ignored if the process PID reference is followed, the drive is in localcontrol mode or PFC (Pump-Fan Control) is active.Note! Parameter 1208 CONST SPEED 7 acts also as a so-called fault speed which may be activated ifthe control signal is lost. Refer to parameter 3001 AI< MIN FUNCTION and parameter 3002 PANEL LOSS .Code Description1201 CONST SPEED SELThis parameter defines which digital inputs are used to select Constant Speeds.0 = NOT SELConstant speed function disabled.1...5 = DI1...DI5Constant Speed 1 is selected with digital inputs DI1-DI5. Digital input activated = Constant Speed 1activated.6 = DI1,2Three Constant Speeds (1 ... 3) are selected with two digital inputs.Constant Speed selection with digital inputs DI1,2.Table 13 Constant Speed selection with digital inputs DI1,2.0 = DI deactivated, 1 = DI activated7 = DI3,4Three Constant Speeds (1 ... 3) are selected with two digital inputs as in DI1,2.8 = DI4,5Three Constant Speeds (1 ... 3) are selected with two digital inputs as in DI1,2.9 = DI1,2,3Seven Constant Speeds (1 ... 7) are selected with three digital inputs.Table 14 Constant Speed selection with digital inputs DI1,2,3.0 = DI deactivated, 1 = DI activated10 = DI3,4,5Seven Constant Speeds (1 ... 7) are selected with three digital inputs as in DI1,2,3.1202-1208CONST SPEED 1...
