Performance description
An SvP Sytronix system features open-loop flow control with alternating closed-
loop pressure control (p/Q control). It can also be operated as a pure, highly
precise hydraulic pressure supply.
The pressure command value for the drive controller ctrlX DRIVE is set by the
higher-level machine control. A pressure transducer senses the actual pressure
value in the hydraulic system and feeds it back to the drive controller ctrlX
DRIVE. The drive controller ctrlX DRIVE controls the speed of the servo motor
so that the hydraulic pump driven by it delivers exactly the oil volume required
for reaching the set pressure. Alternatively, a speed limitation value can be
provided for the drive controller ctrlX DRIVE for controlling the flow. The drive
controller ctrlX DRIVE then adjusts the speed of the servo motor so that the
hydraulic pump driven by it delivers exactly the oil volume that corresponds to
the set value.
