JS120_2Pt Function Block
Overview
The JS120_2Pt function block configures the output of a Sauer-Danfoss JS120 Single Axis
Fingertip Joystick. This joystick has a single two-point y-axis in its base.
The JS120 Joystick uses a spring to return its lever to one end of its travel.
Using the default values supplied in this function block, an input equal to:
• 10% of sensor power voltage causes this joystick to output a value of 0%.
• 90% of sensor power voltage causes this joystick to output a value of 100%.
See:
• Connections and Signals Overview on page 5 for an overview of this function block’s
connections and signals.
• About the Name Space Feature on page 21 if you are using more than one of these
function blocks in your application.
Inputs
JS120_2Pt Function Block Inputs
Input Type Range Description
Para —— —— Allows common parameters to be applied to multiple joystick function blocks.
See About the Para Input on page 19 for more information.
Snsr Pwr —— 0–5260 mV Inputs the sensor power voltage (reference voltage) that the controller applies to the joystick’s sensor power pin.
Y —— 0–5260 mV The voltage on this input indicates the position of the joystick on its y-axis.
The default:
– CalLow calibration value for Y is 10% of the SnsrPwr voltage. A Y input at 10% of the SnsrPwr voltage
outputs a Y_Axis_Psn signal of 0%.
– CalHi calibration value for Y is 90% of the SnsrPwr voltage. A Y input at 90% of the SnsrPwr voltage outputs
a Y_Axis_Psn signal of 100%.

Configuration Settings
Enter the JS120_2Pt page to change the JS120_2Pt function block’s configuration
settings.
When working with configuration settings for PLUS+1 compliant joysticks, note that:
• Configuration inputs with a _Base suffix configure the joystick base.
• Configuration inputs with a _Grip suffix configure the joystick grip.
JS120_2Pt Function Block Configuration Settings
Input Type Range Description
CalMode —— 0–3 Selects the CalMode (Calibration Mode) that sets the CalHi and CalLow values.
– 0—download values with the PLUS+1 GUIDE Service Tool.
– 1—capture values using autocalibration or directly download values with the PLUS+1 GUIDE Service Tool.
In autocalibration, you operate the joystick and the block captures values that fall within defined windows.
– 2—the controller uses the Default calibration values in the Memory page.
– 3—erases all calibration values.
RturnToNeut BOOL —— RturnToNeut (Return to Neutral) sets when the function block enables its Out signals after a controller startup,
calibration, or a Fault or Status condition.
– T—the block enables its Out signals only after all its inputs return to neutral.
– F—the block immediately enables its Out signals.

JS120_2Pt Function Block Configuration Settings
Input Type Range Description
LatchPFlt BOOL —— The function block sets a Status condition when it receives an invalid setup or calibration parameter.
The block disables the signal on the Out pin that is related to the abnormal parameter.
The LatchPFlt (Latch Parameter Fault) sets when the block enables the signal after the condition clears.
– T—the block enables the Out signal only after you repower the controller.
– F—the block immediately enables the Out signal.
LatchInFlt BOOL —— The function block sets a Fault condition when it receives an invalid input.
The block disables the Out signal that is related to the abnormal input.
The LatchInFlt (Latch Input Fault) sets when the block enables the signal after the condition clears.
– T—the block enables the Out signal only after you repower the controller.
– F—the block immediately enables the Out signal.
CalWindow —— 0–3000 The CalWindow (Calibration Window) sets the width of two calibration windows.
These windows center on the default CalHi and CalLow calibration values.
For more information, see About Calibration Windows and Default Calibration Values on page 10.
The default calibration values are set in the Memory page. They are the Default inputs to the two Non-Volatile
Memory Dynamic with Default components in this page.
During autocalibration, input voltages must be within these windows for the function block to capture them as
valid calibration values.
The CalWindow value is set as percentage of SnsrPwr.
1000 = 10.00%.
CalDetectTm —— 0–65535 The CalDetectTm (Calibration Detect Time) sets the time during autocalibration that input voltages must remain
in each calibration window for the function block to capture them as valid CalHi and CalLow calibration values.
1000 = 1000 ms.
Dband_Hi —— 0–4999 The Dband_Hi (Deadband High) sets the width of an upper deadband.
An input voltage within this band produces a 100% output.
This deadband extends below the CalHi calibration value.
The function block sets the width of the Dband_Hi as a percentage of the difference between the CalHi and
CalLow calibration values.
For more information, see About Calibration Values and Deadbands on page 12.
1000 =10.00%.

Input Type Range Description
Dband_Low —— 0–4999 The Dband_Low (Deadband Low) sets the width of a lower deadband.
This deadband extends above the CalLow calibration value.
An input voltage within this band produces a –100% output.
The function block sets the width of the Dband_Low as a percentage of the difference between the CalHi and
CalLow calibration values.
For more information, see About Calibration Values and Deadbands on page 12.
1000 = 10.00%.
FltDetectTm —— 0–65535 The FltDetectTm (Fault Detect Time) sets the time before an abnormal condition causes the function block to set
a Status or Fault condition.
1000 = 1000 ms.

About Calibration Windows and Default Calibration Values
The following graph shows the relationship between the default calibration values and the
windows in which the function block captures calibration values during autocalibration.
• The JS120_2Pt function block’s SnsrPwr is 5000 mV.
• The JS120_2Pt function block’s default:
− CalLow calibration value is 1000, or 10% (500 mV) of SnsrPwr.
− CalHi calibration value is 9000, or 90% (4500 mV) of SnsrPwr.
• The JS120_2Pt function block’s CalWindow (Calibration window) is 1000, or 500 mV
wide (10% of SnsrPwr).
(The Default values for CalLow and CalHi are set in the Memory page. The
CalWindow value is set in the JS120_2Pt page.)
• The 500 mV wide calibration windows center on the Default values for CalLow and
CalHi.

MC Controller—Input Configuration
If you have an SC controller, see SC Controller—Input Configuration on page 17.
You can route the voltage needed by a joystick input though:
• A MFIn (Multifunction Input) on your controller.
• An AnIn (Analog Input) on your controller.
• A DigAn (Digital/Analog input) on your controller.
You must configure the input that you use to accept a voltage input.
MC Controller—How to Configure a MFIn
1. In the GUIDE template, enter the Inputs page.
2. Enter the MFIn page that routes voltage to the input.
3. Delete the route as shown in the preceding figure.

About the Para Input
Use the Para input to apply a common set of parameters to multiple function blocks.
The preceding figure shows a Parameters page that outputs common, shared parameters
to identical function blocks.
The preceding figure shows the contents of the Parameters page that applies the
common, shared parameters to the function blocks.
You create this Parameters page yourself. How you implement parameter sharing
determines the inputs, outputs, contents, and name of this page.
