Group 12: Constant Speeds
This group defines a set of constant speeds. In general:
• You can program up to 7 constant speeds, ranging from 0…500 Hz or 0…30000 rpm .
• Values must be positive (No negative speed values for constant speeds) .
• Constant speed selections are ignored if:
—
The torque control is active, or
—
The process PID reference is followed, or
—
The drive is in local control mode, or
—
PFA (Pump-Fan Alternation) is active .

Defines the digital inputs used to select Constant Speeds. See general comments in introduction.
0 = NOT SEL – Disables the constant speed function .
1 = DI1 – Selects Constant Speed 1 with digital input DI1 .
• Digital input activated = Constant Speed 1 activated .
2…6 = DI2…DI6 – Selects Constant Speed 1 with digital input DI2…DI6 . See above .
7 = DI1,2 – Selects one of three Constant Speeds (1…3) using DI1 and DI2 .
• Uses two digital inputs, as defined below (0 = DI de-activated, 1 = DI activated):
DI1

• See above (DI1,2) for code .
9 = DI3,4 – Selects one of three Constant Speeds (1…3) using DI3 and DI4 .
• See above (DI1,2) for code .
10 = DI4,5 – Selects one of three Constant Speeds (1…3) using DI4 and DI5 .
• See above (DI1,2) for code .

13 = DI3,4,5 – Selects one of seven Constant Speeds (1…7) using DI3, DI4 and DI5 .
• See above (DI1,2,3) for code .
14 = DI4,5,6 – Selects one of seven Constant Speeds (1…7) using DI4, DI5 and DI6 .
• See above (DI1,2,3) for code .
15…18 = TIMED FUNC 1…4 – Selects Constant Speed 1, Constant Speed 2 or the external reference, depending on the state of the Timed Function (1…4)
and constant speed mode . See parameter 1209 TIMED MODE SEL and
on page 35
.
19 = TIMED FUN1&2 – Selects a constant speed or the external reference, depending on the state of Timed Functions 1 & 2 and constant speed mode . See
parameter 1209 TIMED MODE SEL .
-1 = DI1(INV) – Selects Constant Speed 1 with digital input DI1 .
• Inverse operation: Digital input de-activated = Constant Speed 1 activated .
-2…- 6 = DI2(INV)…DI6(INV) – Selects Constant Speed 1 with digital input . See above .
