Signal:u (Output Polarity) - WEST PQP-171-P Technical Documentation Manual

5.5.4 SIGNAL:U (Output polarity)

Command
SIGNAL:U
This command is used to define the type of output signal and its polarity.
Selectable are one solenoid or two solenoid control. Furthermore the direction of the output signal can be
switched. Using applications with one solenoid it means an inverted characteristic curve. If two solenoids are
used it effects the switching of the solenoids.

1S+: One solenoid standard
U = 0... 100% -> IA = 0... 100%
o

1S-: One solenoid inverted
U = 0... 100% -> IA = 100... 0%
o

2S+: Two solenoids standard
o
U > 0 -> Controlling IA
o
U < 0 -> Controlling IB

2S-: Two solenoids switched
o
U > 0 -> Controlling IB
o
U < 0 -> Controlling IA
