Group 13: Analog Inputs - Daikin ACS320 Operation Manual

Group 13: Analog Inputs

This group defines the limits and the filtering for analog inputs and are only needed for units shipping without MicroTech controllers
but need field controls installed.
Table 29: Group 13: Analog Inputs
Code Description
1301 MINIMUM AI1
Defines the minimum value of the analog input.
• Define value as a percent of the full analog signal range. See example below.
• The minimum analog input signal corresponds to 1104 REF1 MIN or 1107 REF2 MIN .
• MINIMUM AI cannot be greater than MAXIMUM AI .
• These parameters (reference and analog min . and max . settings) provide scale and offset adjustment for the reference .
• See figure at parameter 1104.
Example: To set the minimum analog input value to 4 mA:
• Configure the analog input for 0...20 mA current signal.
• Calculate the minimum (4 mA) as a percent of full range
(20 mA) = 4 mA / 20 mA * 100% = 20%
1302 MAXIMUM AI1
Defines the maximum value of the analog input.
• Define value as a percent of the full analog signal range.
• The maximum analog input signal corresponds to 1105 REF1 MAX or 1108 REF2 MAX .
• See figure at parameter 1104.
1303 FILTER AI1
Defines the filter time constant for analog input 1 (AI1).
• The filtered signal reaches 63% of a step change within the time specified.
1304 MINIMUM AI2
Defines the minimum value of the analog input.
• See MINIMUM AI1 above .
1305 MAXIMUM AI2
Defines the maximum value of the analog input.
• See MAXIMUM AI1 above .
1306 FILTER AI2
Defines the filter time constant for analog input 2 (AI2).
• See FILTER AI1 above .
