Festo VPPI D Series User Manual

9.1.3 Contents of the Menu
Menu Level 2 "Input"
Menu option Contents Description
"Input type" "Analog"/"Digital" Appears only for voltage variants. For current vari-
ants, "Input type" = "Analog".
– "Analog": An analogue voltage / current value
via setpoint value (+) and setpoint value (-)
determines the setpoint pressure.
– "Digital": One of 8 setpoint values is specified
via three digital 24 V inputs. For this, the three
inputs are interpreted as a binary number with
3bit.
The assignment is as follows:
– Setpoint value (+): DI0 or least significant bit
– Setpoint value (-): DI1
– Actual value output: DI2 or most significant bit
The value 000 means 0bar and cannot be edited;
the remaining 7 values can be set in "Input values".
There is no actual value output in this mode.

Appears only if "Input type" ="Analog."
Determines the unit in which the setpoint value is
displayed on the main screen.
"Input max" E.g.5V Appears only if "Input type" = "Analog".
Upper limit of the analogue setpoint value range
"Input min" E.g.0V Appears only if "Input type" = "Analog".

Setpoint jumps upwards are filtered with a low-pass
filter. The set value is the time constant (tau) in milli-
seconds.
"Ramp-down-time" "Off"/Xms
X=
75/125/250/500/
750/1000/1500/
2000
Setpoint jumps downwards are filtered with a low-
pass filter. The set value is the time constant (tau) in
milliseconds.
