Group 12: Constant Speeds
The ACS 160 has 7 programmable constant speeds, ranging from 0 to 250 Hz. Negative speed
values cannot be given for constant speeds.
Constant speed selections are ignored if the process PID reference is followed, the drive is in local
control mode.
Note! Parameter 1208
CONST SPEED
7 acts also as a so-called fault speed which may be activated if
the control signal is lost. Refer to parameter 3001

Code Description
1201 CONST SPEED SEL
This parameter defines which digital inputs are used to select Constant Speeds.
0 =
NOT SEL
Constant speed function disabled.
1...5 = DI1...DI5
Constant Speed 1 is selected with digital inputs DI1-DI5. Digital input activated = Constant Speed 1
activated.
6 = DI1,2
Three Constant Speeds (1 ... 3) are selected with two digital inputs.
Constant Speed selection with digital inputs DI1,2.
Table 1 Constant Speed selection with digital inputs DI1,2.
0 = DI deactivated, 1 = DI activated
7 = DI3,4
Three Constant Speeds (1 ... 3) are selected with two digital inputs as in DI1,2.
8 = DI4,5
Three Constant Speeds (1 ... 3) are selected with two digital inputs as in DI1,2.
9 = DI1,2,3
Seven Constant Speeds (1 ... 7) are selected with three digital inputs.
Table 2 Constant Speed selection with digital inputs DI1,2,3.
0 = DI deactivated, 1 = DI activated
10 = DI3,4,5
Seven Constant Speeds (1 ... 7) are selected with three digital inputs as in DI1,2,3.
