Parameter
Number
P0761
Width of deadband
Defines width of deadband on analog input.
Please see following diagrams for explanations of use;
Example 1 – 2 to 10V 0 to 50Hz
P0760 Y2 (100%)
ASPmax
P0758 Y1 (0%)
ASPmin
e above example provides a 2 to 10V, 0 to 50Hz analog input.
P0757 = 2V
P0761 = 2V
P2000 = 50Hz
Example 2 – Center Zero (0 to 10V = - 50 to +50Hz)
ASPmax
P0760 Y2 (100%)
ASPmin
P0758 Y1 (-100%)
The above example provides 0 to 10V, -50Hz to +50Hz with center zero and a "holding
point" 0.2V wide.
P0758 = -100%
P0761 = 0.1 (0.1V either side of center)
P2000 = 50Hz
Note:
Fmin (P1080) should be zero when using center zero setup.
There is no hysteresis at the end of the dead band
