1209 TIMED MODE SEL Selects timed function activated speed into use when parameter 1201
CONST SPEED SEL selection is TIMED FUN1&2.
CS1/2/3/4
EXT/CS1/2/3 External speed reference or constant speed selection with TIMED FUNC 1
and TIMED FUNC 2. 1 = timed function active, 0 = timed function inactive. 1
CS1/2/3/4 Constant speed selection with TIMED FUNC 1 and TIMED FUNC 2.
1 = timed function active, 0 = timed function inactive. 2
13 ANALOGUE INPUTS Analog input signal processing
1301 MINIMUM AI1 Defines the minimum %-value that corresponds to minimum mA/(V) signal for
analog input AI1. When used as a reference, the value corresponds to the
reference minimum setting.
0...20 mA 0...100%
4...20 mA 20...100%
-10...10 mA -50...50%
Example: If AI1 is selected as the source for external reference REF1, this
value corresponds to the value of parameter 1104 REF1 MIN.
Note: MINIMUM AI value must not exceed MAXIMUM AI value.
1%
-100.0…100.0% Value in percent of the full signal range. Example: If the minimum value for
analog input is 4 mA, the percent value for 0…20 mA range is:
(4 mA / 20 mA) · 100% = 20% 1 = 0.1%
1302 MAXIMUM AI1 Defines the maximum %-value that corresponds to maximum mA/(V) signal
for analog input AI1. When used as a reference, the value corresponds to the
reference maximum setting.
0...20 mA 0...100%
4...20 mA 20...100%
-10...10 mA -50...50%
Example: If AI1 is selected as the source for external reference REF1, this
value corresponds to the value of parameter 1105 REF1 MAX.
100
-100.0…100.0% Value in percent of the full signal range. Example: If the maximum value for
analog input is 10 mA, the percent value for 0…20 mA range is:
(10 mA / 20 mA) · 100% = 50% 1 = 0.1%
