Emerson unidrive m200 - Threshold Detector 1 Output; Threshold Detector 2 Output; Threshold Detector 1 Source; Threshold Detector 1 Level

Menu 12 − User Functions 2 and Brake Control
Mode: Open‑loop
Menu 12 provides parameters for the following features:
1. Threshold detectors
2. Variable selectors
3. Mechanical brake controller
Parameter 12.001 Threshold Detector 1 Output
Short description Displays the output of threshold detector 1
Mode Open‑loop
Minimum 0 Maximum 1
Default Units
Type 1 Bit Volatile Update Rate 4ms write
Display Format Standard Decimal Places 0
Coding RO, ND, NC, PT
The threshold detector functions are always active even if the source and destination are not routed to valid parameters. If the source is not a valid parameter then the source value is taken as 0. The
update rate for each of the threshold detector functions is always 4ms.
The following description is for threshold detector 1, but threshold detector 2 operates in the same way. The level of the parameter defined by ThresholdDetector1Source (12.003) is converted to a
percentage and compared to ThresholdDetector1Level (12.004) with hysteresis to give ThresholdDetector1Output (12.001) as follows:
Source Threshold Detector 1 Output (12.001)
Source < Lower threshold 0
Lower threshold ≤ Source < Upper threshold No change of state
Source ≥ Upper threshold 1
Lower threshold = ThresholdDetector1Level (12.004) - (ThresholdDetector1Hysteresis (12.005) / 2)
Upper threshold = ThresholdDetector1Level (12.004) + (ThresholdDetector1Hysteresis (12.005) / 2)
The output value can then be inverted with ThresholdDetector1OutputInvert (12.006) before being routed to the destination defined by ThresholdDetector1Destination (12.007).
