Group 12: Constant Speeds - Daikin MD5 Operation Manual

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 .

Code Description
1201 CONST SPEED SEL
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 DI2 Function
0 0 No constant speed
1 0 Constant speed 1 (1202)
0 1 Constant speed 2 (1203)
1 1 Constant speed 3 (1204)
8 = DI2,3 – Selects one of three Constant Speeds (1...3) using DI2 and DI3 .
• 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 .
11 = DI5,6 – Selects one of three Constant Speeds (1...3) using DI5 and DI6 .
• See above (DI1,2) for code .
12 = DI1,2,3 – Selects one of seven Constant Speeds (1...7) using DI1, DI2 and DI3 .
• Uses three digital inputs, as defined below (0 = DI de-activated, 1 = DI activated):
DI1 DI2 DI3

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
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 .
