Description
Selects timed function activated speed into use when parameter
CONST SPEED SEL selection is TIMED FUN1&2.
External speed reference or constant speed selection with TIMED FUNC 1
and TIMED FUNC 2. 1 = timed function active, 0 = timed function inactive.

Analog input signal processing
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
Note: MINIMUM AI value must not exceed MAXIMUM AI value.
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%
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
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%
