JSPVREL Function Block
Overview
The JS
PVREL function block configures the output of a Sauer-Danfoss JPVREL joystick.
This joystick has a single three-point y-axis in its base with an optional neutral position
switch.
See:
• Connections and Signals Overview
on page 6 for an overview of the JSPVREL function
block’s connections and signals.
• Name Space
on page 21 if your application uses more than one of these function
blocks.
Inputs
JSPVREL Funct
ion Block Inputs
Input Type Range Description
Para —— —— The Para (Parameter) input applies joystick parameters from an external source.
Use this input to apply common parameters to two or more JSPVREL function blocks.
In the GUIDE template, route the bus that carries the common configuration parameters to this input.
To use this input, you must change the configuration of the JSPVREL page to accept parameters from an external
source. See Para Input
on page 18 for more about how to use this input.
Snsr Pwr —— 0–30000 The Snsr Pwr (Sensor Power) input reports the voltage that a PLUS+1 controller applies to the supply voltage pin
on the joystick.
In the GUIDE template, route the Snsr Pwr bus to this input.

JSPVREL Function Block Inputs
Input Type Range Description
Neut Sw —— —— The Neut Sw (Neutral Switch) input applies a Boolean neutral position signal that is output from the joystick’s
optional neutral position switch.
The neutral position signal is T whenever the joystick base is in its mechanically neutral position. A T input causes
the function block to check that the Y input is also in its electrically neutral position. The Y input must fall within a
window defined as
SnsrPwr
± 10%
2
. The function block sets a fault if the
Y input does not fall within this window.
In the GUIDE template, route a bus from the
DigIn or MFIn that inputs the neutral position signal to the Neut Sw
input.
To use this input, you must change the configuration of the
JSPVREL page to apply the neutral position signal to
the function block. For more information, see
Configure to Use the Neut Sw Input on page 20.
If you are using an
MFIn input, you must change its configuration o accept a Boolean signal from the neutral
position switch and avoid a compiler error. For more information, see
Configure an MFIn Input to Accept a Boolean
Input
on page 17.
Y —— 0–30000 Inputs voltage from the joystick that indicates the position of its Y axis.
The default
CalLow (Calibration Low) value for the Y input is 25% of Snsr Pwr. At this input voltage, the function
block outputs
Y_Axis_Psn command of -100%.
The default
CalMid (Calibration Middle) value for the Y input is 50% of Snsr Pwr. At this input voltage, the function
block outputs
Y_Axis_Psn command of 0%.
The default
CalHi (Calibration High) value for the Y input is 75% of Snsr Pwr. At this input voltage, the function
block outputs
Y_Axis_Psn command of +100%.
In the GUIDE template, route a bus from the
AnIn or MFIn that inputs the Y-axis position signal to the Y input.
You must change the configurations of
AnIn and MFIn inputs to accept a voltage input from the joystick and avoid
a compiler error. For more information, see
Configure MFIn and AnIn Inputs to Accept Voltage Inputs on page 15.)

Input Type Range Description
CalMode —— 0–3 Selects the CalMode (Calibration Mode) that sets the CalHi, CalMid, 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 position 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.

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
Out signal that is related to the abnormal parameter.
The
LatchPFlt (Latch Parameter Fault) determines 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) determines 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 three calibration windows.
These windows center on the default
CalHi, CalMid, and CalLow calibration values.
For more information, see
Calibration Windows and Default Calibration Values on page 11.
The default calibration values are set in the
Memory page. They are the Default inputs to the three Non-Volatile
Memory Dynamic with Default
components in this page.
During autocalibration (
CalMode = 1), input voltages must fall 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%
CalDetectTm —— 0–65535 The CalDetectTm (Calibration Detect Time) sets the time, during autocalibration, that input voltages must stay
within each calibration window before the function block can capture them as valid calibration values.
1000 = 1 s
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
CalMid calibration values.
For more information, see
Calibration Values and Deadbands on page 13.
1000 =10%
Dband_Mid —— 0–4999 The Dband_Mid (Deadband Middle) sets the width of a middle deadband.
An input voltage within this band produces a 0% output.
This deadband has an upper and lower half. The upper half extends above the
CalMid calibration value. The
lower half extends below the
CalMid calibration value.
The function block sets the width of the upper half of
Dband Mid as a percentage of the difference between the
CalHi and CalMid calibration values.
The function block sets the width of the lower half of
Dband Mid as a percentage of the difference between the
CalMid and CalLow calibration values.
