0…17,

1 1 (AI1)

Selects the signal source for external reference REF1.
0 = KEYPAD – Denes the control panel as the reference source.
1 = AI1 – Denes analog input 1 (AI1) as the reference source.
2 = AI2 – Denes analog input 2 (AI2) as the reference source.
3 = AI1/JOYST – Denes analog input 1 (AI1), congured for joystick operation, as the
reference source.
• The minimum input signal runs the drive at the maximum reference in the reverse
direction. Dene the minimum using parameter 1104.
• The maximum input signal runs the drive at maximum reference in the forward
direction. Dene the maximum using parameter 1105.
• Requires parameter 1003 = 3 (REQUEST).
WARNING! Because the low end of the reference range commands full reverse
operation, do not use 0 V as the lower end of the reference range. Doing so means
that if the control signal is lost (which is a 0 V input) the result is full reverse operation.
Instead, use the following set-up so that loss of the analog input triggers a fault,
stopping the drive:
• Set parameter 1301 MINIMUM AI1 (1304 MINIMUM AI2) at 20% (2 V or 4 mA).
• Set parameter 3021 AI1 FAULT LIMIT to a value 5% or higher.
Does not apply to
Daikin MicroTech III applications.
• Set parameter 3001 AI<MIN FUNCTION to 1 (FAULT).
4 = AI2/JOYST – Denes analog input 2 (AI2), congured for joystick operation, as the reference source.
• See above (AI1/JOYST) description.
5 = DI3U,4D(R) – Denes digital inputs as the speed reference source (motor potentiometer control).
• Digital input DI3 increases the speed (the U stands for “up”).
• Digital input DI4 decreases the speed (the D stands for “down”).
• A Stop command resets the reference to zero (the R stands for “reset”).
•
Parameter 2205 ACCELER TIME 2 controls the reference signal’s rate of change. Does not apply to Daikin MicroTech III applications.
6 = DI3U,4D – Same as above (DI3U,4D(R)), except:
• A Stop command does not reset the reference to zero. The reference is stored.
• When the drive restarts, the motor ramps up (at the selected acceleration rate) to the stored reference.
7 = DI5U,6D – Same as above (DI3U,4D), except that DI5 and DI6 are the digital inputs used.
8 = COMM – Denes the eldbus as the reference source.
9 = COMM+AI1 – Denes a eldbus and analog input 1 (AI1) combination as the reference source. See Analog input reference correction below.
10 = COMMAI1 – Denes a eldbus and analog input 1 (AI1) combination as the reference source. See Analog input reference correction below.
1
1 = DI3U,4D(RNC) – Same as DI3U,4D(R) above, except that:
• Changing the control source (EXT1 to EXT2, EXT2 to EXT1, LOC to REM) does not copy the reference.
12 = DI3U,4D(NC) – Same as DI3U,4D above, except that:
• Changing the control source (EXT1 to EXT2, EXT2 to EXT1, LOC to REM) does not copy the reference.
13 = DI5U,6D(NC) – Same as DI5U,6D above, except that:
• Changing the control source (EXT1 to EXT2, EXT2 to EXT1, LOC to REM) does not copy the reference.
14 = AI1+AI2 – Denes an analog input 1 (AI1) and analog input 2 (AI2) combination as the reference source. See Analog input reference correction below.
15 = AI1AI2 – Denes an analog input 1 (AI1) and analog input 2 (AI2) combination as the reference source. See Analog input reference correction below.
16 = AI1-AI2 – Denes an analog input 1 (AI1) and analog input 2 (AI2) combination as the reference source. See Analog input reference correction below.
17 = AI1/AI2 – Denes an analog input 1 (AI1) and analog input 2 (AI2) combination as the reference source. See Analog input reference correction below.
20 = KEYPAD(RNC) – Denes the control panel as the reference source.
• A Stop command resets the reference to zero (the R stands for reset.).
• Changing the control source (EXT1 to EXT2, EXT2 to EXT1) does not copy the reference.
21 = KEYPAD(NC) – Denes the control panel as the reference source.
• A Stop command does not reset the reference to zero. The reference is stored.
• Changing the control source (EXT1 to EXT2, EXT2 to EXT1) does not copy the reference.
Analog Input Reference Correction
Parameter values 9, 10 and 14…17 use the formula in the table at the right.
Where:
• C = Main reference value ( = COMM for values 9, 10 and = AI1 for values 14…17).
• B = Correcting reference ( = AI1 for values 9, 10 and = AI2 for values 14…17).
Example:
The gure shows the reference source curves for value settings 9, 10 and 14…17, where:
• C = 25%.
• P 4012 SETPOINT MIN = 0.
• P 4013 SETPOINT MAX = 0.
• B varies along the horizontal axis.

Value setting Calculation of the AI reference
C + B C value + (B value - 50% of reference value)
C * B C value · (B value / 50% of reference value)
C - B (C value + 50% of reference value) - B value
C / B (C value · 50% of reference value) / B value
