Pressure and flow control system SYDFE1 series 2X, 3X
35/96
Circuitry of SYDFE1 with control electronics with power limitation
(VT 5041-3X/3-...)
Fig. 13: Circuitry of SYDFE1 for master/slave and independent individual operation
Notes:
• Set the pressure transducer input on the slave axis to 0...10 V.
• The connection for the position transducer of the pump is not drawn here.
• The coupling element (relay, analog switch) can be optionally installed to
control both pumps independently of one another. With the proposal shown
here, both, swivel angle and pressure control are possible with the slave
pump.
• For the master/slave operating mode, the signal p
comm
(II) must be set to
maximum (+10 V).
• If closed-loop pressure control is to be realized also in the master/slave
operating mode, only the pressure transducer of the master is evaluated for
controlling purposes. If hydraulically separated operation should be possible,
too, a separate pressure transducer is required for the slave.
