Festo P.BE−S PC200−EN en 0901d
The measured values are passed on from the axis interface to
the SPC200 Smart Positioning Controller. The SPC200 com
pares the nominal position with current position and calcu
lates from this value the positioning signal for the propor
tional directional control valve.
The proportional directional control valve controls the drive
by pressurizing one drive
chamber and exhausting the other.
In the mid−position the flow is blocked so that the drive stops
typically at the current position.
