Threshold Detector 1 Source; Threshold Detector 1 Level; Threshold Detector 1 Hysteresis; Threshold Detector 1 Output Invert - Control Techniques Commander SK Advanced User's Manual

Menu 12 Introduction Parameter x.00
Menu 12 includes two threshold detectors which produce logic signals depending on the level of a variable value with respect to a threshold, and two
variable selectors which allow two input parameters to be selected or combined to produce a variable output. A function is active if one or more
sources are routed to a valid parameter.
12.01 Threshold detector 1 output indicator
12.02 Threshold detector 2 output indicator
Bit SP
Coding
1
Range 0 or 1
Update rate 21 ms
These parameters indicate whether the threshold input variable is above (1) or below (0) the programmed threshold.
12.03

Threshold detector 1 source

Bit SP
Coding
1
Range Pr 0.01 to Pr 21.51
Update rate Read on drive reset
This parameter and Pr 12.23 define the parameter to be input to the programmable threshold.
The absolute value of the source variable is taken as input to the threshold comparator. Only non-bit parameters can be programmed as a source. If
a non valid parameter is programmed the input value is taken as 0.
12.04

Threshold detector 1 level

Bit SP
Coding
Range 0.0 to 100.0 %
Update rate 21 ms
This parameter and Pr 12.24 are the user defined threshold levels entered as a percentage of the source maximum.
12.05

Threshold detector 1 hysteresis

Bit SP
Coding
Range 0.0 to 25.0 %
Default 0.0
Update rate 21 ms
This parameter and Pr 12.25 define the band within which no change will occur on the output.
The upper limit for switching is:Level + Hysteresis/2
The lower limit for switching is:Level - Hysteresis/2
12.06

Threshold detector 1 output invert

Bit SP
Coding
1
Range 0 or 1
Default 0
Update rate 21 ms
This parameter and Pr 12.26 are used to invert the logic states of the threshold output if required.
12.07 Threshold detector 1 destination
Bit SP
Coding
Range Pr 1.01 to Pr 21.51
Default Pr 0.00
Update rate Read on drive reset
This parameter and Pr 12.27 define the parameter which is to be controlled by the threshold parameter. Only bit parameters which are not protected
can be set up as a destination. If a non valid parameter is programmed the output is not routed anywhere.
