Group 12: Constant Speeds - Daikin ACS320 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 and Fan Alternation) is active
NOTE: Parameter 1208 CONST SPEED 7 acts also as a so-called fault speed which may be activated if the control signal is
lost . For example, see parameters 3001 AI<MIN FUNCTION, 3002 PANEL COMM ERROR and 3018 COMM FAULT
FUNC .
Table 28: Group 12: Constant Speeds
Code Description
1201 CONST SPEED SEL
Defines the digital inputs used to select Constant Speeds. See general comments in the 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...5 = DI2...DI5 – Selects Constant Speed 1 with digital input DI2...DI5 . 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
• Can be set up as a so-called fault speed, which is activated if the control signal is lost . Refer to parameter 3001 AI<MIN function and parameter 3002
PANEL COMM ERR .
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 .
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 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
13 = DI3,4,5 – Selects one of seven Constant Speeds (1...7) using DI3, DI4 and DI5 .
• See above (DI1,2,3) for code .
15...18 = TIMER 1...4 – Specifies the timer used to select a Constant Speed as the reference. The reference selection depends on the state of the selected
timer, and the value of 1209 TIMED MODE SEL . See table . To enable and set timers, see Group 36, Timer Functions .
1201 = 15 16
Timer: 1
Timer State
15...18 = TIMER FUNCTION 1...4 – Selects Constant speed 1 when Timer Function is active . See Group 36, Timer Functions .
19 = TIMER 1 & 2 – Selects a constant depending on the state of Timers 1 & 2 .
See parameter 1209 .
