PLUS+1® Compliant S7 PVE Function Block with SP Option
S7 PVE Function Block with Spool Position (SP) Option
This function block controls the output of Danfoss Series 7 valve actuators configured for a spool position
(SP) option.
An analog voltage signal on the dedicated SP output pin lets you derive the position of the main spool.
The spool position output is derived from the LVDT spool position.
Inputs
Inputs to the function block are described.
Item Type Range Description
Sp_Pin Bus —— Analog input from the valve actuator to notify the valve actuator’s status – error warning or spool
position.
Outputs
Outputs of the function block are described.
Item Type Range Description
Fault U16 —— This signal indicates if input values are valid. It’s a bitwise code, so multiple items can be reported at a
time.
0x0000 There is no fault.
0x8001 Input value too high.
0x8002 Input value too low.
When there is an error, the output Sp_Pos is set to 0.
Sp_Pos S16 -700 to 700 Spool position.
Fault Logic
Fault logic detects problems that can occur in the function block.
Fault Hex Cause Response Delay Latch Correction
Input too low. 0x8001 Input value < 400 mV Sp_Pos set to 0 No No Check wire harness for open or
Input too high. 0x8002 Input value > 4750 mV Sp_Pos set to 0 No No Check wire harness for short circuit.
