Configuration
February 2023
Enter here the limit value for functions with limit monitoring. The unit of the limit value for
the function output is in [rpm] for the speed and in [rpm/s] for acceleration. Parameter
Value 1 must always be smaller than Value 2.
Hysteresis
Enter here the hysteresis. The hysteresis shall avoid an undefined switching of the assigned
binary output, if the measuring value constantly moves around the limit value. The
hysteresis value does only have an effect, when a limit value has been violated.
The threshold for resetting the function output is the limit value minus hysteresis for
increasing switching characteristics and the limit value plus hysteresis at decreasing
switching characteristics.
Mode
Select the operating principle for the corresponding function output and the Channel OK
output from the list field.
Open-circuit mode
In Open-circuit mode the initial state of a function output means an output signal of 0
V and the active state (condition for the output is met) an output signal of +24 V.
Closed-circuit mode
In Closed-circuit mode the initial state of a function output means an output signal of
+24 V and the active state (condition for the output is met) an output signal of 0 V.
Example for function output configured for >= Limit Value and mode Closed-circuit
mode:
The initial state of the function output shows a level of +24 V. When the measuring value
exceeds the limit value, the condition is met and the function output switches to 0 V.
Test
Define and activate here the test values for testing the AMS 6300 SIS monitor. The test
values must be sent to the monitor before use. See
