PLUS+1 Compliant S42 NFPE Control Function Block
User Manual
S42_12V_NFPE Function Block
Overview
The S42_12V_NFPE function block interfaces between your application and a SauerDanfoss S42 12 V DC NFPE (Non-Feedback Proportional Electric) control that is used with Sauer-Danfoss pumps. The output of this function block drives the coils that control flow direction and flow magnitude through the pump’s A and B ports.
TPLUS+1 I/O modules do not have the fault-checking feedback signals that are needed by this function block. An application that uses this function block to control an I/O module will fail to compile.
See:
•About Function Block Connections on page 10 for an overview of this function block’s connections and signals.
•About the Name Space Feature on page 26 if you are using more than one of these function blocks in your application.

Function Block Parameters
Warning
Using the PLUS+1 Service Tool program 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 download new parameter values.
The following table lists function block parameters that are stored in the controller’s nonvolatile memory.
You can change these values by:
•Execution of the calibration process.
•Direct access to serial EE memory using the PLUS+1 Service Tool.
•Recalling default values.

S42_12V_NFPE Function Block
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 (EE_EndCrnt, MaxCrnt).
•ThldApplied = MIN ((EE_Thld × ThldMult), EndCrntApplied).
This assures that:
•EndCrntApplied never exceeds MaxCrnt.
•ThldApplied never exceeds EndCrntApplied.
Also note that, while the CalTask value is set to select a calibration task:
•EndCrntApplied = MaxCrnt.
•ThldApplied = 1.
The applied values are available in the Diag bus as Thld_A, Thld_B, EndCrnt_A, and
EndCrnt_B.
