Overview

User Manual
S90_EDC Function Block
The output of an S90_EDC function block interfaces between your application and a
Sauer-Danfoss S90 EDC (Electronic Displacement Control). The output of this function
block drives the coils that control flow direction and magnitude through a pump’s A and B
ports.
T PLUS+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 9 for an overview of this function block’s
connections and signals.
• About the Name Space Feature on page 25 if you are using more than one of these
function blocks in your application.
Inputs
S90_EDC Function Block Inputs
Input Type Range Description
Pwr —— —— Reports controller power supply voltage.
The function block uses this voltage when it calculates the measured resistance of the control circuit.
Fdbk_A —— —— Reports the status of the MFOut (Multifunction Output) block that receives the function block’s Out_A (Output 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. The Inputs bus on the Application page contains these Status buses.
Fdbk_B —— —— Reports the status of the MFOut (Multifunction Output) block that receives the function block’s Out_B (Output 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. The Inputs bus on the Application page contains these Status buses.

S90_EDC Function Block Inputs
Input Type Range Description
Setup —— —— Allows common configuration to be applied to multiple function blocks.
See About Modifying the Config_Data Page on page 15 for more information.
Enable BOOL —— Enables the OutputValue signals in the Out_A and Out_B buses.
– T = OutputValue signals follow the CmdIn signal.
– F = Holds both OutputValue signals at zero.
– F/T = Clears latched faults if CmdIn is zero.
CmdIn S16 ±10000 Specifies the requested speed and direction.
– +10000 = Requests maximum Out_A speed.
– 0 = Requests neutral (stop).
– –10000 = Requests maximum Out_B speed.
Function Block Internal Constants
The following table lists constant values that are provided in the function blocks for
setting limits. These constants cannot be edited.
S90_ED
Constant Value Description
MaxCrnt 100 mA The maximum current for displacement or proportional control.
Nominal Ω 18.0 Ω The resistance of the load normally connected to Out_A and Out_B.

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.

Parameter Type Range Description
A.EE_Thld,
B.EE_Thld
A.EE_EndCrnt
B.EE_EndCrnt
A.EE_CalFlg,
B.EE_CalFlg
Function Block Parameters
U16 CalThldMin to CalThldMax Calibrated threshold values for Out_A and Out_B.
U16 Thld + 1 to MaxCurrent Calibrated end current values for Out_A and Out_B.
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.

S90_EDC Function Block
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.
