Overview
The S45_Angle_Sensor function block monitors the angle sensor output from an S45 Angle Sensor
installed in a Series 45 pump. The output of this function block provides your application with the S45
pump's:
•
Swash plate angle position in percent.
•
Output in cubic centimeters.
See:
•
About Function Block Connections on page 6 for more about this function block's connections and
signals.
•
About the Name Space Feature on page 12 if you are using more than one of these function blocks in
your application.
Inputs
This function block ships with its EE_Cal_Min and EE_Cal_Max values set at 0.
Function Block Inputs
Item Type Range Description
Para Bus —— Input for external parameter values.
See About the Para Input on page 8 for more information.
Min Displ U16 0–200 The minimum displacement of the pump.
100 = 100 cc
Max Displ U16 0–200 The maximum displacement of the pump.
100 = 100 cc
Cal Task U8 0–4 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 EE_Cal_Min value.
For example, if the pump outputs its minimum displacement with SIG1 input at 2500 mV and a Snsr
Pwr of 5000 mV, then the function block stores an EE_Cal_Min value of 5000 (50.00%).
•
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 EE_Cal_Max value.
For example, if the pump outputs its maximum displacement with SIG1 input at 4000 mV and a Snsr
Pwr of 5000 mV, then the function block stores an EE_Cal_Max value of 8000 (80.00%).
•
3 = Set both the EE_Cal_Min and the EE_Cal_Max to their default values.
•
4 = Clear calibration values.

Function Block Inputs (continued)
Item Type Range Description
Snsr Pwr Bus —— Voltage supplied to the swash plate angle sensor.
The function block uses the Snsr Pwr and SIG1 signals and the EE_Cal_Min and EE_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 an MC controller, the value inputs through the Volt signal.
•
On an SC controller, the value inputs through the Voltage signal.
Volt
U16 4,750–5,250 Voltage supplied to the swash plate angle sensor.
1,000 = 1,000 mV.
Voltage

1,000 = 1,000 mV.
SIG1 Bus —— Signal from the swash plate angle sensor that indicates, through voltage, the position of the pump
swash plate.
The function block uses the Snsr Pwr and SIG1 signals and the EE_Cal_Min and EE_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 an MC controller, the value inputs through the Volt signal.
•
On an SC controller, the value inputs through the Voltage signal.

Voltage U16 0–5,250 Signal from the swash plate angle sensor that indicates the position of the pump swash plate.
1,000 = 1,000 mV.
SIG2 Bus —— A second signal from the swash plate angle sensor that indicates, through voltage, the position of the
pump swash plate.
The function block monitors the SIG2 signal to ensures the integrity of the SIG1 signal.
The function block declares a fault whenever the difference between the SIG1 and SIG2 signals
becomes:
•
Greater than 600 mV.
•
Less than 400 mV.
The function block receives this value through either a Volt signal or a Voltage signal:
•
On an MC controller, the Volt signal inputs this value.
•
On an SC controller, the Voltage signal inputs this value.

Figure Details
Item Description
1. The EE_Cal_Min value sets the percentage of Snsr Pwr at which the SIG1 input to the function block produces threshold Displ and Pct
outputs.
In this example:
•
The Snsr Pwr is 5000 mV.
•
The EE_Cal_Min value is 5000 (50.00%).
(50% of 5000 mV is 2500 mV).
•
A 2500 mV SIG1 input to the function block produces threshold Pct and Displ outputs.
2. The EE_Cal_Max value sets the percentage of Snsr Pwr at which the SIG1 input to the function block produces maximum Displ and Pct
outputs.
In this example:
•
The Snsr Pwr is 5000 mV.
•
The EE_Cal_Min value is 8000 (80.00%).
(80% of 5000 mV is 4000 mV).
•
A 4000 mV SIG1 input to the function block produces maximum Pct and Displ outputs.

With a Deadband Value
Figure Details
Item Description
1. The Dband value sets the width of a lower deadband that extends above the SIG1 input that produces the threshold pump output.
The function block calculates this deadband as a percentage of the difference between the SIG1 input voltage that produces threshold Pct
and Displ outputs and the SIG1 input voltage that produces maximum Pct and Displ outputs.
In this example, with Snsr Pwr at 5000 mV:
•
The Dband value is 2000 (20.00%).
•
The difference between the threshold SIG1 and the maximum SIG1 voltages is 1500 mV (4000-2500 = 1500).
•
The lower deadband is 300 mV wide.
(20.00% of 1500 mV is 300 mV.)
2.
The Dband value also sets the width of an upper deadband that extends below the SIG1 input that produces the maximum pump output.
The function block calculates this deadband as a percentage of the difference between the SIG1 input voltage that produces threshold Pct
and Displ outputs and the SIG1 input voltage that produces maximum Pct and Displ outputs.
In this example, with Snsr Pwr at 5000 mV:
•
The Dband value is 2000 (20.00%).
•
The difference between the threshold SIG1 and the maximum SIG1 voltages 1500 mV (4000-2500 = 1500).
•
The upper deadband is 300 mV wide.
(20.00% of 1500 mV is 300 mV.)

About the Name Space Feature
If you use this function block more than once in an application, you must change each function block’s
Name Space value to avoid compiler errors.
This function block contains one or more components that allocate memory using memory names
(“aliases”). Identical function blocks have identical memory names. Identical memory names cause
compiler errors.
The Name Space value adds a unique prefix to each component name to avoid errors. Keep each Name
Space value short to save controller memory.
How to Enter a Name Space Value
1. In the PLUS+1 GUIDE menu bar, click the Query/Change button.
2. Click the function block’s page name to display the Edit Page window.
3. In the Edit Page window, enter a meaningful Name Space value.
4. Press Enter.
5. Repeat these steps to enter unique Name Space values for other identical function blocks.
