PN Pipe network
PS Pressure sensor
Fig. 11-1: Automatic constant pressure water control system
● The set value of pressure is set by analog value digital setting E3.01.
The pressure feedback from output VR2 corresponds to a value of
0...10 V.
● [E3.00] = 2, [E3.03] = 4. E3.04, E3.05, E3.06, and E3.07 are set de‐
pending on actual conditions.
11.1.2 Closed-loop Speed Control System
Fig. 11-2: Closed-loop speed control system
● Conditions and requirements:
PGP2 is connected to the operational power supply of pulse encoder, and
the set value of speed is set by rotation speed digital setting E3.02. [E3.00] =
4, S2.12 is set according to the specification of the feedback encoder.
