I/O modules do not have the fault-checking feedback signals that are needed by these function
blocks. Applications that use these function blocks to control an I/O module do not compile.
For more about these function blocks’ connections and signals, see Function Block Connections.
If you are using more than one of these function blocks in your application, see Using the Name Space
Feature.
Inputs
The inputs of the function block are described.
Item Type Range Description
Pwr Bus —— Reports controller power supply voltage.
The function block uses this voltage when it calculates the measured resistance of the control circuit.
Fdbk_A Bus —— Reports the status of the MFOut (Multifunction Output) block that receives the function block’s Out_A
bus.
(Each MFOut block in the Outputs page has a corresponding MFOut block in the Inputs page that
reports on its status through a Status bus.)
Fdbk_B Bus —— Reports the status of the MFOut (Multifunction Output) block that receives the function block’s Out_B
bus.
(Each MFOut block in the Outputs page has a corresponding MFOut block in the Inputs page that
reports on its status through a Status bus.)
Setup Bus —— Allows common configuration values to be applied to multiple function blocks.
See Configuration Values for more information.
Enable BOOL —— Enables the OutputValue signals in the Out_A and Out_B buses.
•
True = OutputValue signals follow the CmdIn signal.
•
False = Holds both OutputValue signals at zero.
•
False/True = Clears latched faults if CmdIn is zero.
CmdIn S16 ±11,000 Specifies the requested speed and direction.
•
+10,000 = Requests the maximum Out_A output.
•
0 = Requests neutral (stop).
•
–10,000 = Requests the maximum Out_B output.
+10,000 = +100.00%.
-10,000 = -100.00%.
If you want to override the command to the pump, use a value greater than 10,000.

Function Block Parameters
This topic describes function block parameters that are stored in the controller’s non-volatile memory.
W
Warning
Using the PLUS+1
®
Service Tool to download new parameter values to an application can result in
unexpected and sudden machine movements.
Unexpected and sudden machine movements can result in personal injury and equipment damage.
Always secure your machine against unexpected and sudden movements before you use the PLUS+1
®
Service Tool to download new parameter values.
You can change these values by:
•
Execution of the calibration process.
•
Direct access to parameters stored in non-volatile memory through the PLUS+1
®
Service Tool.
•
Recalling default values.
Function Block Parameters
Parameter Type Range Description
NV_A_Thld
NV_B_Thld
U16 CalThldMin to CalThldMax Calibrated threshold values for Out_A and Out_B.
1000 is 1,000 mA.
NV_A_EndCrnt
NV_B_EndCrnt
U16 Thld + 1 to MaxCurr Calibrated end current values for Out_A and Out_B.
1000 is 1,000 mA.
NV_A_CalFlg
NV_B_CalFlg
U8 —— Calibration flags for Out_A and Out_B.
•
Bit 1 = 1 (0x0001)—Threshold is not calibrated.
•
Bit 2 = 1 (0x0002)—End current is not calibrated.
The CalFlg signal in the Diag bus contains both pairs of flags,
with the Out_B bits shifted to positions 3 and 4.
These parameters determine the values used as threshold and end current for each direction during
normal operation. However, the values actually applied might be different because:
•
Thld and EndCrnt are both subject to range limits.
•
Thld is modified by the ThldMult value.
The following intermediate values represent the values that are actually applied:
•
EndCrntApplied = MIN (NV_EndCrnt, MaxCrnt).
•
ThldApplied = MIN ((NV_Thld × ThldMult), EndCrntApplied).
This assures that:
•
EndCrntApplied never exceeds MaxCurr.
•
ThldApplied never exceeds EndCrntApplied.
Also note that, while the CalTask value is set to select a calibration task:
•
EndCrntApplied = MaxCurr.
•
ThldApplied = 1.
The applied values are available in the Diag bus as Thld_A, Thld_B, EndCurr_A, and EndCurr_B.

A delayed fault gets reported if the detected fault condition persists for a specified delay time. A delayed fault cannot be cleared until the fault
condition remains undetected for the delay time.
‡
A latched fault report maintains until the latch is released. A release is attempted each time that Enable becomes True while CmdIn is 0.
§
The nominal Ω value is an internal constant of each function block. It can be viewed, with other defined constants, in the Define sub-bus of the Diag
bus. The other constants specify the maximum current and the range limits for configuration values.
Configuration Values
The default Config page contains constant values that set the function block’s operating characteristics.
Typically, you do not have to change any of these values for the correct operation of the function block.
Optionally, you can:
•
Modify the constant values on this page.
•
Replace some or all of the constant values on this page with signals brought in on the Setup bus,
which is connected to the function block’s Setup input. For more information, see Modify the Config
Page.

CalTask S16 –2 to +3 –2 to +3 CalTask (Calibration Task) selects a calibration process.
•
–2 = Calibrate the B end current.
•
–1 = Calibrate the B threshold.
•
0 = Not in the calibration mode.
•
+1 = Calibrate the A threshold.
•
+2 = Calibrate the A end current.
•
+3 = Applies default calibration values for both outputs on a
transition to +3. The default value of +3 applies default
values each time the controller powers up, and allows normal
operation.
StoreCalVal BOOL —— —— While calibration is active, a StoreCalVal (Store Calibration
Value) False/True transition writes the selected calibration value
to memory and sets the CalFlg to indicate this value as
calibrated.
The CalFlg in the Diag bus reports the status of each calibration
value.
•
True = Not calibrated.
•
False = Calibrated.
SetCalReqd BOOL —— —— A False/True transition sets all CalFlg bits to 1 to mark all
calibration values as uncalibrated.
ClrCalReqd BOOL —— —— A False/True transition clears all CalFlg bits to 0 to mark all
calibration values as calibrated.
CalThldMin U16 0–7,199 0–3,679 Sets the lower limit of the valid range for the threshold
parameters.
10,000 = 1,000 mA.
CalThldMax U16 7,200–10,800 3,680–5,520 Sets the upper limit of the valid range for the threshold
parameters.
10,000 = 1,000 mA.
ThldMult U16 0–10,000 0–10,000 The function block multiplies the Out_A and Out_B thresholds
by the ThldMult (Threshold Multiplier) to calculate the applied
threshold.
Enter a value of less than 10,000 to reduce the applied
threshold. For example, a value of 7,500 reduces both the
Out_A and Out_B thresholds by 25%.
10,000 = 100.00%.
DfltThld_A U16 CalThldMin to CalThldMax CalThldMin to CalThldMax When the CalTask becomes +3, the Out_A threshold

10,000 = 1,000 mA.
DfltThld_B U16 CalThldMin to CalThldMax CalThldMin to CalThldMax When the CalTask becomes +3, the Out_B threshold parameter
resets to equal the DfltThld_B(Default Threshold B).
10,000 = 1,000 mA.
DfltEndCrnt_A U16 0–1,800 0–920 When the CalTask becomes +3, the Out_A end current
parameter resets to equal the DfltEndCrnt_A (Default End
Current A).
10,000 = 1,000 mA.
DfltEndCrnt_B U16 0–1,800 0–920 When the CalTask becomes +3, the Out_B end current

Input Type 12V Range 24V Range Description
EnFltDet BOOL —— —— The EnFltDet (Fault Detection) signal enables detection of open
and short conditions, based on the measured resistance of the
EDC control circuit.
•
True = Enable fault detection.
•
False = Disable fault detection.
FltDetectTm U16 100–2,000 100–2,000 Sets the time before the fault detection logic reports or clears
fault conditions.
This value specifies how long a fault condition must be
detected before it is reported. It also specifies how long the
fault condition must remain undetected before the report can
be cleared.
1,000 = 1,000 ms.
ResFltCurr U16 —— —— For each direction, the open and short faults are only detected
while the OutputValue exceeds the Resistance Fault Current.
Typically, set this value below the Out_Aand Out_B threshold
values.
If you set the value:
•
Too low, you get nuisance faults.
•
Too high, you turn off fault detection for some or all of the
output range.
1,000 = 100.0 mA.
NegCrntThld U16 —— —— Negative feedback current in an uncommanded direction must
be greater than the NegCrntThld (Negative Current Threshold)
value to set a fault.
Typically, this fault results when the A and B outputs drive coils
that share a common ground and their connection to the
controller ground is lost.
1,000 = 100.0 mA.
FdbkFltrTime U16 —— —— Sets the time constant for the exponential filtering applied to
the current measurement used to detect a fault caused by
negative feedback in an uncommanded direction.
1,000 = 1,000 ms.
Modify the Config Page
You can modify the Config page to control the configuration process with signals routed into the
function block from an application.

Calibrate the Function Block
This topic describes how to calibrate the function block.
See Modify the Config Page for an example of a Config page that has been modified to allow an
application to control the calibration process.
1. Prepare to calibrate.
a) Set the SetCalReqd signal to False.
b) Set the ClrCalReqd signal to False.
c) Set the StoreCalVal signal to False.
d) Toggle the SetCalReqd signal from False to True.
Toggling sets the “not calibrated” bits in the CalFlg signal to 1.
2. Set the Enable signal to True.
3. Calibrate the Out_A threshold parameter.
a) Set the CalTask signal to +1.
b) Gradually modify the CmdIn signal in a positive (0 to +10,000) direction to find the minimum
command that causes motion.
In the Status signal, monitor bit 7—Value too low and bit 8—Value too high to make sure that
the OutputValue signal is within the valid threshold range.
c) Toggle the StoreCalVal signal from False to True to write the OutputValue to memory.
In the CalFlg signal, check that bit 1 clears to 0, to verify that the controller has written the Out_A
threshold parameter to memory.
4. Calibrate the Out_B threshold parameter.
a) Set the CalTask signal to –1.
b) Gradually modify the CmdIn signal in a negative (0 to –10,000) direction to find the minimum
command that causes motion.
In the Status signal, monitor bit 7—Value too low and bit 8—Value too high to make sure that
the OutputValue signal is within the valid threshold range.
c) Toggle the StoreCalVal signal from False to True to write the OutputValue to memory.
In the CalFlg signal, check that bit 3 clears to 0, to verify that the controller has written the Out_B
threshold parameter to memory.

b) Gradually modify the CmdIn signal in a positive direction to find the command that produces the
desired maximum pump flow.
c) Toggle the StoreCalVal signal from False to True to write the OutputValue to memory.
In the CalFlg signal, check that bit 2 clears to 0, to verify that the controller has written the Out_A
end current parameter to memory.
6. Calibrate the Out_B end current parameter.
a) Set the CalTask signal to –2.
b) Gradually modify the CmdIn signal in a negative direction to find the command that produces the
desired maximum pump flow.
c) Toggle the StoreCalVal signal from False to True to write the OutputValue to memory.
In the CalFlg signal, check that bit 4 clears to 0, to verify that the controller has written the Out_B
end current parameter to memory.
7. End the calibration process.
a) Set the CalTask signal to 0.
b) In the CalFlg signal, verify that all bits are now 0.
c) Verify that no Status or Fault conditions are reported.
d) Set the ThldMult signal to the desired value.
Calibrate an Individual Parameter
You can use the PLUS+1
®
Service Tool to manually calibrate the function block by downloading
calibration parameters.
Partial calibration allows you to calibrate an individual parameter while leaving the values of other
parameters unchanged.
1. Prepare to calibrate.
a) Set the SetCalReqd signal to False.
b) Set the ClrCalReqd signal to False.
c) Set the StoreCalVal signal to False.
d) Toggle the SetCalReqd signal from False to True.
Toggling sets all the “not calibrated” bits in the CalFlg signal to 1.
2. Set the Enable signal to True.
3. Use the CalTask signal to select the parameter to be calibrated.
4. Calibrate the parameter.
a) Toggle the StoreCalVal signal from False to True to write the OutputValue to memory.
b) In the CalFlag signal, check that the calibration bit for the selected parameter clears to 0; this
verifies that the controller wrote the parameter to memory.
5. End the calibration process.
a) Set the CalTask signal to 0.
b) Toggle the ClrCalReqd signal from False to True.
c) In the CalFlg signal, verify that all bits are now 0.
d) Verify that no Status or Fault conditions are reported.

Service Tool to manually calibrate the function block by downloading
calibration parameters.
W
Warning
Using the PLUS+1
®
Service Tool to download new parameter values to an application can result in
unexpected and sudden machine movements.
Unexpected and sudden machine movements can result in personal injury and equipment damage.
Always secure your machine against unexpected and sudden movements before you use the Service
Tool program to download new parameter values.
When you manually calibrate:
•
Make sure that the calibration parameters are valid. If the values are out of range for a given direction,
the block limits the values of ThldApplied, EndCrntApplied or both for that direction. This condition
is indicated by the “Parameters are corrupt” Status, but it can produce unintended output
commands.
•
Verify that the Status signal indicates normal status conditions.

Namespaces can help you successfully compile an application that uses the same function block more
than once.
Change each function block's namespace by setting its Name Space value to something unique. If you
do not change the Name Space value, you cannot compile the application.
The Name Space value adds a unique prefix to each component name.
Also, if you want to use these function blocks' companion Service Tool screens, you must include the
function block's advanced checkpoint with namespace in the application's compiled .lhx file. Use the
function block's Checkpoints page to include the checkpoint.
Change Name Space Value
To successfully compile your application, change the Name Space value for function blocks that are used
more than once in an application.
