Daikin MD5 - Group 12: Constant Speeds

Group 12: Constant Speeds
This group denes 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.

Denes 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 dened 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 dened below (0 = DI de-activated, 1 = DI activated):
DI1 DI2 DI3 Function
0 0 0 No constant speed
1 0 0 Constant speed 1 (1202)
0 1 0 Constant speed 2 (1203)
1 1 0 Constant speed 3 (1204)
0 0 1 Constant speed 4 (1205)
1 0 1 Constant speed 5 (1206)
0 1 1 Constant speed 6 (1207)
1 1 1 Constant speed 7 (1208)
1 1 0 Constant speed 4 (1205)
0 1 0 Constant speed 5 (1206)
1 0 0 Constant speed 6 (1207)
0 0 0 Constant speed 7 (1208)
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.
