H1 EDC Angle Sensor Function Block

The H1_EDC_Ang_Snsr function block monitors the angle sensor output from an H1 EDC Angle Sensor installed in an H1 EDC pump.
The output of this function block provides your application with the pump's:
Swash plate angle position in percent.
•
Direction of pump flow.
•
See:
Function Block Connections for more about this function block's connections and signals.
•
Identical Function Blocks Need Different Namespace Values to Successfully Compile if you are using more
•
than one of these function blocks in your application.

Inputs

The following section describes input signals to the H1 EDC Angle Sensor function block.
This function block ships with its NV_Cal_Min, and NV_Cal_Max values set at 0.
Item Type Range Description [Unit] Para Bus —— Input for external parameter values.
See Para Input for more information.
Cal Task U8 0–5 Controls the function block's calibration process:
•
0 = Disable calibration.
•
1 = Calibrate the percentage of Snsr Pwr that the SIG1 input must reach for the pump to output its minimum displacement. Store this percentage as the NV_Cal_Min value.
For example, if the pump outputs its maximum reverse displacement with SIG1 input at 1000 mV and a Snsr Pwr of 5000 mV, then the function block stores an NV_Cal_Min value of 2000 (20.00%).
•
2 = Calibrate the percentage of Snsr Pwr that the SIG1 input must reach for the pump to output its maximum displacement. Store this percentage as the NV_Cal_Max value.
For example, if the pump outputs its maximum forward displacement with SIG1 input at 4000 mV and a Snsr Pwr of 5000 mV, then the function block stores an NV_Cal_Max value of 5000 (50.00%).
•
3 = Set NV_Cal_Min and NV_Cal_Max to their default values.
•
4 = Clear calibration values.
Snsr Pwr Bus —— Voltage supplied to the swash plate angle sensor.
The function block uses the Snsr Pwr and SIG1 signals and the NV_Cal_Min and NV_Cal_Max values to make a ratiometric calculation of the swash plate angle sensor's position and its faults. The function block receives this value through either a Volt signal or a Voltage signal:
•
On Legacy MC controllers, the value inputs through the Volt signal.
•
On SC and Non-Legacy MC controllers, the value inputs through the Voltage signal.
