Proportional Valve Driver Mode
Selection from Menu ->
Control Logic-> Valve Control Mode
This mode allows you to adjust the coil
current based on the command input. This
method is typically used in situations
where the output current needs to be
controlled directly using a joystick.
The valve driver can operate in either dual
coil or single coil mode. Figure A shows
the characteristics of the valve driver mode
in dual coil mode which is ideal for
directional valve control or for pump swash
control.
Figure 8 shows single coil characteristic
which is ideal for flow or pressure control
operation.

Valve Driver Mode with dual coils
Figure B Coil Current vs. Command Voltages in
Valve Driver Mode with single coil
IMPORTANT NOTE – DUAL COIL OPERATION:
The output of either ‘A’ or ‘B’ output will go from the respective ‘I Min’ setting to ZERO (0mA ) when
crossing through command mid-point. The valve outputs do NOT jump from one I Min to the other.
